Full textAbstract:
Syfte: Syftet med denna studie är att undersöka:
- Lean filosofins påverkan på Banken X administrativa processer.
- Samt huruvida Lean Kan vara ett verktyg/process för att förbättra de administrativa Processerna.
Dessutom är våra frågeställningar dessa:
- Hur påverkar Lean de administrativa processerna i Banken X?
- Kan administration bli Lean?
- Hur kan Banken X arbeta för att implementera Lean på det mest effektiva sättet?
Metod: Denna studie har den kvalitativa metoden som ansats. Teorin för denna studie har hämtats från relevanta vetenskapliga teorier inom aktuellt ämne. Vidare genomfördes denna insamling av information i syfte för att underlätta förståelsen samt skapa en insikt i ämnet. I förfarande för denna studie har vi valt den deduktiva metoden att arbeta efter, resultatet är intervjuer av tre medarbetare från Banken X huvudkontor. Det empiriska underlaget har sedan sammanställts med den teoretiska materiellt där vi har skildrat likheter och olikheter.
Resultat & slutsats: Denna studie påvisar att Lean kan öka värdeskapande för de administrativa processerna, samt att administration kan bli Lean, men inte i samma omfattning och effektivitet som Lean faktiskt har haft på verkstadsindustrin. Vidare att det kanske svåraste i arbetet med Lean faktiskt är implementeringen och acceptansen av medarbetarna.
Förslag till fortsattforskning: Vi anser att det skulle vara intressant att om ett par år studera Banken X eller för den delen en annan administrativ organisation för att se huruvida Lean Administration har fått ett fäste eller inte och för att se om värde och värdeskapande har identifierats på ett mer effektivt sätt
Uppsatsens bidrag: Förhoppningen med denna studie är att belysa Lean konceptets påverkan på administrativa organisationers processer. Vi är övertygade om att dagens knivskarpa konkurrens bidrar till att fler och fler organisationer inte längre lyckas överleva på den tuffa marknaden. Dessutom är vi övertygade om att i den globala värld som vi lever i är det mycket viktigt och centralt att organisationer har tydliga och strukturerade processer i sitt dagliga arbete för att lyckas vidmakthålla sig.
Nyckelord: Lean, Muda, Värde, Värdeskapande & Kaizen
Aim: The purpose of this study is to investigate:
- The Lean philosophy’s impact on the Bank X administrative processes.
- And whether Lean Can be a tool/process to improve the administrative processes.
Further are our issues these:
- How does Lean affect the administrative processes in the Bank X?
- Can administration become Lean?
- How can Bank X work to implement Lean in the most efficient way?
Method: This study is the qualitative method approach. The theory of this study is taken from the relevant scientific theories in the current topic. Furthermore we took this collection of information in order to facilitate understanding and create an understanding of the subject. The procedure for this study, we have chosen the deductive method to work after, the result are from the interviews of three employees from the Bank X headquarters. The empirical basis has been compiled with the theoretical material which we have described the similarities and differences
Result & Conclusions: This study demonstrates that Lean can increase the value of administrative processes, and that the administration can become Lean, but not to the same extent and effectiveness of Lean actually has had on the engineering industry. Furthermore, it is perhaps most difficult in the work with Lean is actually the implementation and acceptance by the employees.
Suggestions for future research: We think it would be interesting to in a couple of years studying Bank X or, for that matter, a different administrative organization to see whether Lean Administration has received an attachment or not and to see if value and valuecreating have been identified in a more efficient manner
Contribution of the thesis: The hope of this study is to highlight the Lean concept's impact on the organizations' administrative processes. We are convinced today's sharp competition contributes to more and more organizations no longer manage to survive in the tough market. In addition, we are convinced that in the global world we live in, it is very important and crucial that organizations have clear and structured processes in their daily work in order to succeed in maintaining itself.
Key words: Lean, Muda, Value, Valueadding & Kaizen

Resumo: O lean thinking e o design thinking são modos de pensar aplicados ao desenvolvimento, produção e gestão de bens e serviços. O primeiro articula-se em função da atribuição de valor pelo cliente e é voltado para a redução do desperdício. O segundo tem suas ações centradas no usuário e é voltado para a inovação. Baseando-se na análise dos seus princípios, este trabalho de pesquisa identifica as aproximações teóricas e as relações entre as duas áreas. A metodologia envolve a revisão de literatura e a análise qualitativa da amostra constituída pelos textos com os princípios do lean thinking e do design thinking e cinco artigos sobre cada um dos dois temas. O tratamento qualitativo dos dados utiliza a estratégia de codificação e pauta-se na Teoria Fundamentada nos Dados (TFD). Para a operacionalização do trabalho de análise qualitativa por meio de codificação utiliza-se o software ATLAS.ti. Os diferentes níveis de codificação permitem identificar 12 aspectos de aproximação entre as duas áreas. Uma análise final desse conjunto leva aos cinco mais relevantes: cliente, experiência, iteração, inovação e valor. Desta análise também deriva uma convergência teórica que possibilita entender como estes aspectos se relacionam entre si em termos de identificação do agente, definição do processo e constituição do ativo. Também permite inferir que a atribuição de valor é o aspecto que estrutura as relações entre o lean thinking e o design thinking. Os resultados da pesquisa apresentam um novo olhar sobre a dinâmica das relações destas duas áreas e abrem horizontes para aplicação prática destas conexões assim como para novos estudos sobre o tema.
Abstract: Lean thinking and design thinking are ways of thinking applied to the development, production and management of goods and services. The first is articulated according to the value assignment by the client and is aimed at reducing waste. The second has its actions focused on the user and is geared towards innovation. Based on the analysis of its principles, this research identifies the theoretical approaches and the relationship between the two areas. The methodology involves a literature review and a qualitative analysis of two texts with the principles of lean thinking and design thinking and five articles on each of the two themes. The qualitative data processing uses the coding strategy and is referenced on the Grounded Theory. In order to implement qualitative analytical work through coding is used ATLAS.ti software. The different levels of coding allow to identify 12 aspects of rapprochement between the two areas. From this set, a final analysis led to the five most relevant: customer, experience, iteration, innovation and value. This analysis also derives a theoretical convergence that enables to understand how these aspects relate to each other in terms of agent identification, process definition and constitution of assets. Also allows to infer that the value assignment is the aspect that structures the relationship between lean thinking and the design thinking. The research results present a fresh look at the dynamics of the relationship of these two areas and open horizons for practical application of these connections as well as for further studies on the subject.

Mestrado em Engenharia e Gestão IndustrialAtualmente, o ambiente competitivo empresarial exige das organizações um esforço cada vez maior pela sobrevivência do negócio. As empresas procuram reduzir custos, aumentar as margens de lucro e diferenciar a sua oferta da concorrência. A filosofia Lean Thinking vai de encontro a estas necessidades, providenciando metodologias para a obtenção desses objetivos. Apesar da simplicidade dos princípios Lean, a sua implementação numa determinada organização nem sempre é fácil. É neste sentido que a formação na área do Lean Thinking assume uma elevada importância para a evolução das organizações, dotando os seus colaboradores de conhecimentos indispensáveis para atingir os padrões de produção desejados. Este projeto pretende desenvolver situações simuladas para demonstração das metodologias Lean, em sala de aula e em ambiente industrial. O objetivo destas simulações é a disseminação da filosofia Lean Thinking e a demonstração prática das suas metodologias e ferramentas, como por exemplo o sistema Pull, o mapeamento do fluxo de valor (VSM) e os 5S. Neste trabalho foram desenvolvidas duas simulações para sala, a linha de refrigerantes e a montagem de legos, e uma simulação para ambiente fabril.
Nowadays, the competitive business environment demands an increasingly effort from organizations for business survival. Companies seek to reduce costs, increase profit margins and differentiate their offering from the competition. Lean Thinking philosophy meets these needs by providing methodologies to obtain these goals. Despite the simplicity of Lean principles, its implementation in a particular organization is not always easy. This is why training in the field of Lean Thinking assumes a great importance for the evolution of organizations by providing their employees essential knowledge to achieve the desired production standards. This project aims to develop simulated situations to demonstrate the Lean methodologies, in the classroom and in industrial environments. The purpose of these simulations is the spread of Lean Thinking philosophy and practical demonstration of its methodologies and tools, such as Pull System, Value Stream Mapping (VSM) and 5S. In this work were developed two simulations for classroom, the soft drink line and assembling Lego’s, and a simulation for production environment.

Full textAbstract:
Software intensive systems are an increasing part of new products, which make the business impact significant. This is especially true for the automotive industry where a very large part of new innovations are realized through the use of software. The architecture of the software intensive system will enable value creation when working properly or, in the worst case, prevent value creation. Lean thinking is about focusing on the increase of customer value and on the people who add value. This thesis investigates how system architecting is performed in industry and how it can be improved by the use of Lean thinking. The architecting process does not create immediate value to the end customer, but rather create the architecture on which value in terms of product features and functionality can be developed. A Lean tool used to improve the value creation within a process is Value Stream Mapping (VSM). We present a method based on VSM which is adapted to enable analysis of the architecting process in order to identify improvements. A study of architecting at two companies shows what effect differences such as a strong line organization or a strong project organization has on the architecting process. It also shows what consequence technical choices and business strategy have on the architecting process. In order to improve the understanding of how architecting is performed a study including architects at six different internationally well-known companies have been interviewed. The study presents the practices that are found most successful. The context of the different companies as well as the architecting practices are compared and analyzed. The early design decisions made when developing software-intensive systems are crucial to the outcome of development projects. In order to improve the decision making process a method was developed based on Real Options. The method improves the customer focus of critical design decision by taking the value of flexibility into account. This thesis provides a toolbox of knowledge on how Lean thinking can be applied to system architecting and also presents how architecting is performed in industry today.

Full textAbstract:
In the new business economy, project management has become a central way for undertaking several of the business activities. One of the increasing and most significant concerns with projects is that, projects are behind schedule, over budget and show unsatisfactory performance in terms quality and customer satisfaction. In the last few decades the manufacturing industry successfully improved quality and productivity, by using the concepts of lean thinking. The thesis explores the relevance of lean concepts in project management and how lean concepts can improve project productivity. The qualitative method is used in this study. Further, a systematic approach was used to identify the relevance of lean concepts in project management. The qualitative data was collected using an interview with a project consultant. The results of the study reveal that all concepts of lean thinking are relevant to project management in specific kinds of projects. However, a greater degree of understanding and interpretation of each concept is needed when applying lean thinking in project management. Furthermore, some of the concepts have to be interpreted with caution when they are used in innovative projects. In general, it is found that, lean project management can improve project productivity. The findings suggest that the lean concepts can reduce cost and time which are two key measures of project success. The results of this study can be seen as a tentative framework intended to stimulate further discussion about integrating lean thinking in project and program management.

AGES är ett företag som pressgjuter produkter i aluminium med olika legeringar. De producerar främst till fordons- och verkstadsindustrin. De har i dagsläget låg total utrustningseffektivitet på två av sina maskiner och vill få reda på varför. De största tidsförlusterna är ställtiderna samt att operatörerna inte märker att maskinstopp har skett. Målet med examensarbetet var att identifiera och reducera slöseri i produktionsprocessen hos AGES och skapa en grund för framtida arbete med SMED och Lean Production. Genom olika mätningar kunde olika analyser utföras såsom värdeflödesanalys och OEE-analys. Analyserna resulterade i ett antal förbättringsförslag där vissa av dem planeras att implementeras. Vissa hamnade under utvärdering och vissa hamnade som framtida förbättringar. Studien har också bidragit till en ökad förståelse för varför maskinstopp sker och vilka åtgärder som bör vidtas. Ledningen på AGES är positiva till resultatet av studien och förbättringsförslagen. Inom SMED har det resulterat i en plan till hur verktygsbytet kan gå till för att minska ställtiderna samt hur mycket tid som kan besparas vid implementering.AGES is a company that die-cast aluminum products with various alloys. They mainly produce for the automotive and engineering industries. Currently they have a low total equipment efficiency on two of their machines and they want to find out why. The biggest time losses are the set-up times and that the operators are not noticing when a machine stop has occurred. The aim of the project was to identify and reduce waste in the production process at AGES and create a basis for future work with SMED and Lean Production. Through different measurements, different analyzes could be performed such as value flow analysis and OEE-analysis. The analyzes resulted in several improvement proposals, some of which are planned to be implemented. Some will be evaluated and will be implemented as future improvements. The study has also led to an understanding of why machine stops occur and what measures should be taken. The management at AGES is positive to the results of the study and the improvement proposals. Within SMED, it resulted in a plan for how the tool change can be done to reduce set-up times and how much time can be saved when implemented.

Full textAbstract:
A study has been conducted into improving construction design through the application of the lean thinking paradigm. Its objective was to identify the issues relating to design efficiency and how a lean thinking approach might address these issues. The investigation consisted of examining work already undertaken in the field by other researchers"to identify the state of the art. The change order request system was examined to gain first insights into waste in construction design, and to gauge the size of the opportunity for the application of lean thinking. An Electronic Data Gathering Tool (EDGT) was then developed to allow further exploration of the design decision making process at the system / sub-system level. The EDGT was used on three live construction projects. From the data recorded a design planning tool, Design Decision Planner (DDP), was created to help improve control of the design process and lead to a more standardised approach to construction design. Standardising the approach to product development is an important component of lean thinking. The main recommendations for making construction design lean are: Use DDP to plan and improve control of the design decision making process, assign design responsibility and to make the process more transparent. 2. Measuring progress against planned design is a useful process metric. 3. Improve the designer's cost and programme visibility when choosing between design options. 4. Redefine the role of the quantity surveyor from cost controller to value for money assessor. The role needs to be better integrated into the design process to reach its full potential. 5. Need to develop more rigorous methods of assessing the buildability of design options. This problem could be eased in the short-term by incorporating construction professionals into the early design phases. 6. Designers need to use more process reason drivers when choosing between design options, not just functional criteria. 7. The change order request system could be redesigned to identify the root causes of contract issue design changes and, hence, improve the design decision making process.

Full textAbstract:
Customer’ demands, higher quality, faster and safer deliveries are some reasons for unexpected changes in the organizations. It has incremented complexity and cost. Lean production is known as a methodology to make improvements in manufacturing areas such as mentioned above and it is focused on the process of a product. But, Lean Thinking is a management strategy to make improvements in the process of a product or service and it is based on five principles. It allows having the process close to the customer eliminates tasks that do not add value and produces with low costs and high quality. However, there are some concepts ambiguous to be applied effectively to the Radio Access Network area in wireless telecom industry as a service company. Radio Access Network area transmits Radio frequency (RF) signals from the Radio Base Station (RBS) to the user equipment (UE) or mobile phone and is an area to present dynamic changes by high technology innovation. Therefore, the aim of this study is to identify improvements through for the Radio Access Network area. This thesis was structured to know how the five Lean principles and Lean tools can be used in the Radio Access Network area and the benefits that it could have. The study was realized through a qualitative research and five semi-structured interviews. A manager, team leaders and engineers of wireless telecom industry vendor and operators were the participants for this study. The results of major impact for Lean principles and Lean tools were VSM and Flow principles and Waste as Lean tool found for the Radio Access Network area. Project definition, resource planning and VOC were some improvements revealed for VSM principle. Furthermore, faster and optimal tools, training for engineers, knowledge in software and employee empowerment were some improvements found for Flow principle. Waste Lean tool showed some improvements found on customer’s focus, clear communication and waiting time reduction. Cross functional teams were other aspects that provided quality performance in the projects. This study seemingly is a good start for making decisions and for the high technology innovation and dynamic changes for telecom service companies.

Efficient engineering processes are critically important for furniture manufacturers. Engineering impacts the production cost, design quality, product lead time, and customer satisfaction. This research presents a systematic approach to analyze a furniture engineering process through a case study. The research was conducted through a case study in a furniture plant located in China, producing American style furniture products. The first stage was to investigate the companyâ s current engineering process, identify non value-added activities, and analyze the engineering performance based on selected Key Performance Indicators (KPIs) such as lead time, document error rate, and engineering throughput. A survey questionnaire was sent out to the engineering group to determine the current engineering efficiency.
Results show that â product complexityâ and â engineer competencyâ are the two most influential factors that impact engineering lead time and quality. In the second stage, value stream mapping was used to analyze an upholstery furniture engineering process. The approach encompasses an analysis of the current state of the engineering process and the proposal of a lean future state value stream map (VSM).
Results from the current state VSM show, that the value-added ratio of the current engineering process is only 26%. Several engineering steps present deficiency such as the processes of creating drawings, compile mass production documents, check and sign-off engineering documents, create CNC programs, and generate packaging files. Based on current state VSM analysis, the researcher focused on transforming these processes to eliminate waste and to propose the best practices for the future state VSM.
From this research, it shows that current processes include a large amount of non-value adding activities such as waiting, extra processing, rework, excess motion, transportation, underutilized people, and inefficient information. These non-value adding activities are interfering with engineersâ ability to prepare engineering documents for downstream jobs and affecting the overall manufacturing process. The VSM is effective to provide the visual control over the engineering process for implementing lean transformations.Master of Science

Lean management is becoming the standard for systematic productivity improvement, but the majority of implementations fail to sustain. Hence, the critical success factors for lean were the focus of this work. Literature review showed that the causality for lean success was not empirically developed beyond case study contextualisation. A multifaceted work was developed with contextualisation studies, survey of lean knowledge (758 responses), and a comprehensive case-study questionnaire (1253 responses from 44 countries). The statistical methods included exploratory factor analysis and path analysis by structural equation modelling (SEM). The first questionnaire revealed two different understandings of lean, and the second explored the underlying causality for lean success, including contingency for business size and product variety.
Many contributions to the body of knowledge issued from this work. First of all, there was a methodological contribution, pioneering explorative structural modelling of full scope lean implementation. Second, SEMs of the lean knowledge-based view showed the profound positive effects of management knowledge on the primary factors for lean success. These factors were shown to be leadership and employee development. Third, the most beneficial lean methods were highlighted for specific scenarios. Fourth, the negligible and negative effects of a consultant-based approach to lean were uncovered. The results showed that the majority of consultants did not aid the long-term performance and sustainability of lean but significantly hindered it, except where masterful consultants acted as coaches. Fifth, a shortage of lean knowledge was observed in New Zealand; their participants averaged only half of what the USA�s did. Sixth, as culture has been emphasised in current literature, the present danger of overly focusing on it was discussed. Seventh was a conceptual contribution integrating lean and risk management, and a practical application with a risk analysis. This developed a risk matrix for the assessment and prioritisation of implementation components. Eighth, some adjustments to government lean strategies were proposed. And finally, the work integrated the findings in a tangible stage process model for implementation in SMEs.
The dissemination of this knowledge has the potential to enhance productivity and commercial success of industries in New Zealand and abroad through successful lean implementations. Lean is not a weak methodology but it has been misunderstood and misapplied.

The Supply Planning Operations team, in a large manufacturing firm, faced a future where their complexity of scope was increasing without an increase in resource levels. As an effort to improve both efficiency and effectively within the organization, they chose to adopt Lean Thinking as a method to streamline and simplify activities, connections and flows. Lean Thinking, while often viewed as a set of tools (value stream mapping, andon cords, kanbans, and others), involves the harmony between principles, culture and the appropriate application of tools. SPO has taken an approach focused on culture and deep understanding of Lean Principles before deploying the tools of Lean. It was important to examine why artifacts succeeded or failed in influencing cultural change. One common theme for successful artifacts was their portability. With a geographically diverse team, it was important that any artifact could be transported electronically. Although not all the actions have been successful in influencing the organization's culture, many actions have had a profound impact. Seeing members of the organization write about their personal experiences is just one example of how Lean Thinking has been adopted. By committing to "Rules before Tools," the group embarked upon a journey to change culture. This thesis used an Enacted Systems Analysis to identify Artifacts, Habits of Thought and Habits of Action. Several organizational barriers emerged along with possible levers to promote change. Even though the revolution is only in its infancy, SPO appears to be on a sustainable path toward a Lean Thinking transformation.

Full textAbstract:
Lean Thinking is a method of work organization that promotes the creation of value and elimination of waste. United States Department of Defense (DoD) acquisition organizations currently struggle with many non-Lean processes that inhibit cost-effective, on-time completion of projects. The author hypothesized that by applying Lean Thinking to Satellite Control and Network Systems Group (SCNG) processes, a dedicated project team would enhance unit productivity and reduce costs related to the Livelink file sharing database system. To do this, SCNG members formed a Lean project team, pursued Lean Thinking training, and applied Lean to Livelink processes. This resulted in improvements of 100% - 500% for file manipulation and data sharing processes, which saved the Government up to $8,960 per week. The project also demonstrated that Lean Thinking can successfully be applied to the acquisition program office environment.

Titel En kvalitativ fallstudie om hur företag förhåller sig till gapet mellan den operativa och den strategiska delen av Lean Nivå Kandidatuppsats Författare Igor Jovanović och Linnea Juhlin Handledare Stig Sörling och Tomas Källquist Datum Maj 2014 Problem Tidigare forskning har påvisat att det finns ett gap i företagens användning av styrverktyget, där företagen i stor utsträckning förbiser vikten av den strategiska delen av Lean. Detta har gjort att företag har haft svårigheter att uppnå sina mål med användandet av styrverktyget. Syfte Syftet är att skapa förståelse för hur tillverkande företag förhåller sig till gapet mellan den operativa och den strategiska delen av Lean, samt belysa de beståndsdelar gapet består av. Metod Studien har antagit ett hermeneutiskt och socialkonstruktivistiskt perspektiv där tematisering och ett deduktivt tillvägagångssätt har använts. Studien har genom kvalitativ metod med fallstudiedesign studerat fyra stora företag med hjälp av semistrukturerade intervjuer. Teori En genomgång av Lean-konceptet görs för att skapa förståelse för styrverktyget sedan fördjupar vi oss på den strategiska delen av Lean för att kartlägga de olika beståndsdelarna som kan överbrygga gapet. Bidrag Gapet framträder inte lika tydligt i vår studie, fallföretagen har i sitt tankesätt störst fokus på den strategiska delen av Lean. Kultur och ledarskap är huvudbeståndsdelar i jobbet med att överbrygga gapet där den strategiska delen ämnar skapa positiv energi hos medarbetarna. Studien indikerar på att svårigheter med att införliva de teoretiska kunskaperna i praktiken ökar risken för att gapet ska uppstå. Nyckelord: Lean Production, Lean Thinking, Lean kultur, Gap, operativ, strategisk, Dualism.Title A qualitative case study research on companies attitude towards the gap between the operational and the strategic part of Lean Level Bachelor thesis Authors Igor Jovanović and Linnea Juhlin Supervisor Stig Sörling and Tomas Källquist Date May 2014 Problem Earlier research has shown that there is a gap in how companies work with Lean where they largely overlook the importance of the strategic part of Lean. Due to this, companies have difficulties to achieve their goals with the use of the management tool. Purpose The purpose of this report is to create an understanding of manufacturing companies’ attitude towards the gap between the operational and the strategic part of Lean, and to highlight the components that the gap might consist of. Method The study adopts a hermeneutic and social constructionist perspective where thematisation and a deductive approach have been used. A qualitative approach with case study design has been used to study four large companies using semi-structured interviews. Theoretic frame A review of the Lean concept has been conducted to create an understanding of the management tool. The study has then focused on the strategic part of Lean to identify the different components that may help to bridge the gap. Contribution The gap is not as evident in our empirical study as in our theoretical framework. It appears as companies do have their focus on the strategic parts of Lean, at least in their way of thinking. Culture and leadership are essential components in the efforts towards bridging the gap. The strategic part of Lean intends to create positive energy among employees. The study indicates that a difficulty in incorporating the theoretical knowledge in practice increases the risk of creating the gap. Key words: Lean Production, Lean Thinking, Lean Culture, Gap, Operational, Strategic, Dualism

Full textAbstract:
As competitively tendering for work is becoming increasingly difficult, and with profit margins reducing, UK construction companies are looking to differentiate their offering to clients. Safely delivering on time, within budget and to the required quality standard is no longer a differentiator in a market where clients are demanding increased value, building information modelling and life cycle provision. Construction companies are therefore looking to extend their activities into business consulting, financing and operational services, which will provide new sources of revenue in addition to their core production activities. This holistic service should provide solutions that meet their client s business needs, not just their building needs, ultimately resulting in long-standing relationships that over time yield a more predictable, long-term return. Over half of the top 20 UK construction companies, by turnover, have stated their intent to provide solutions to their clients - the case study organisation in which this research has been carried out is one of those companies. Part of a group of companies, the case study company, Shepherd Construction Ltd (SCL), has a vision to deliver integrated solutions to their clients, with the ultimate aim being that companies across the group can pool their expertise and deliver a service offering unique to the industry. Existing literature states the characteristics that integrated solutions providers need to possess, and proposes models for how an organisation needs to structure itself to deliver a service. However, the applicability of these models to SCL was unknown, and along with current literature on how to enact the transition pathway being vague, highlighted an area for investigation. Since the aim of integrated solutions provision is the delivery of a service to the client that adds value, it was proposed that lean thinking could provide a means of enacting the P-S transition: the starting point for lean thinking is value (Womack & Jones, 2003). Lean thinking principles (Womack & Jones, 2003) state that value needs to flow through the value stream the series of actions that transform inputs into the completed output raising the further proposition that flow is required through the stages of the integrated solutions lifecycle (the value stream) in order to successfully deliver all aspects of the client s value proposition, i.e. the desired solution. As a long established main-contractor, or product provider, SCL s challenge to transition from products-to-services was set against a backdrop of inconsistent performance and loss of continuity of service at crucial pinch-points in the delivery process. The action research carried out therefore sought to understand these problems and develop practices based on lean thinking that could be implemented in the company to enable consistent delivery of integrated solutions, i.e. enable the products-to-service transition, and in doing so provide the basis for the wider group vision. An abductive approach was taken to the research strategy; the experiences of the participants involved in the changes prompted by the action research process were used to inform the development of new theories and practices, and evaluate them once implemented. The methods used for collecting data and accounting for the experiences of people in the company included observation, both participant and non-participant, semi-structured interviews and analysis of company records. The research findings show that lean thinking has a role to play in enabling an organisation to transition from the provision of products to services. Standard processes and tools, based on lean thinking and developed through the action research framework, are shown to be the basis for consistent and repeatable performance within the phases of the integrated solutions lifecycle. Flow of information through and between phases of the lifecycle is then shown to be essential to ensuring the client s value proposition is realised and information is not lost during the transitions between lifecycle phases. The operational framework for service delivery , one of the practices developed, itself a form of standardised work, draws on lean thinking to provide a structured, yet flexible, means of developing a plan for service delivery that is focused on the client and ensuring the client s definition of value flows through the integrated solutions value stream and is therefore continually understood, and ultimately delivered, by the whole team as the project progresses. The practices developed through the research the standard company management system, operational framework for service delivery , service delivery plan and maturity assessment are shown to have improved consistency and company performance, and to have contributed to improved customer satisfaction (the ultimate aim of delivering a service) such that the company is starting to be perceived in the marketplace as an integrated solutions provider. This research also contributes to existing theory by evidencing that the transition pathway from products-to-services isn t as smooth as current literature portrays. In trying to implement current models in a construction setting, the products-to-service transition has been problematised and deficiencies in existing characteristics and models identified. Along with showing that lean thinking provides a theoretical framework for enacting the products-to-service transition, the hybrid model of the integrated solutions lifecycle developed, along with the maturity assessment, provide new theoretical insights, such as the need for feedback loops between all phases of the lifecycle.

The application of Lean principles and practices has been shown to help aerospace companies reduce waste and maximize value to help meet the changing demands of the market. The most visible area of influence has been manufacturing, where great strides have been made in cost and cycle time reduction. Recently, the flight testing community has been faced with similar challenges. This paper investigates whether Lean principles can be applied to aircraft flight testing and evaluation to help meet these goals. Specific objectives are to identify opportunities for the implementation of Lean thinking and establish a framework for structured implementation of Lean principles and practices. This study focuses on seven aircraft programs: 737-NG, 767-400, Hawker Horizon, F-22, F/A-18E/F, C-130J, and the T-6A. The programs are analyzed from a programmatic viewpoint to identify where lean practices are currently being used and how lean thinking could further improve the overall flight testing process. Additionally, a detailed examination is performed on the day-to-day activities to identify the daily sources of waste and their impact on the program. The detailed analysis focuses on flutter testing as a surrogate for the entire testing program. A total of 90 flights were analyzed. Data collected from the case studies fits well into the value-creation framework established in Lean Enterprise Value. Each of the phases of the framework - value identification, value proposition, and value delivery - are discussed as they relate to flight testing. Many examples of the application of lean principles and practices as well as opportunities for implementation are presented in the value delivery phase. Opportunities were identified in: coordination of the systems engineering value stream, coordination with other test aircraft and necessary support functions, and management of the daily test operations. This preliminary study indicates that Lean thinking can be applied to flight testing. The guiding principles of well-run testing programs paralleled those of Lean. Additionally, there are many instances where Lean thinking would provide an opportunity to eliminate waste and improve efficiency.

Full textAbstract:
This research project aims to develop a novel A3 thinking approach to support knowledge driven design that aids the generation of decision making within a Lean Product and Process Development (LeanPPD) environment. This research comprises the development of a new A3 template as a technique of problem solving in product design, the adoption of a reflection practice structured in a new A3 template for knowledge capture and sharing, and the generation of the process of using the A3 thinking approach for effective implementation. Providing useful knowledge as a design reference to generate decision making at the initial stages of product development in product design helps the designers to prevent recurrence of the same problem, eliminate design mistakes and enhance design decision. In order to achieve a novel A3 thinking approach, a research methodology consisting of four phases was developed. The first phase synthesises the A3 best practice through literature and documentation reviews. The gap analysis and results from the reviews have identified several problem-solving approaches and learning cycles that have to be considered in the research. The second phase is to evaluate the approaches and their impacts and applications in product design. In order to complete this, several research methods are selected and performed (e.g. focus group and semistructured interview) within the collaborative companies. The third phase is to develop the A3 thinking approach by utilising the LAMDA learning cycle, developing a new A3 template or so-called A3LAMDA, adopting the reflection practice and generating the process of using the new A3 thinking approach. Finally, the validation of the new A3 thinking approach through industrial case studies and expert judgements have been performed. This approach has been implemented in the automotive sector and was applied to four industrial case studies and six A3LAMDA reports were collected. As a result of the findings of this research, the utilisation of the A3 thinking approach aided the generation of knowledge driven design in product design by integrating the knowledge management capabilities; knowledge creation, capture and sharing.

Mestrado em Engenharia e Gestão IndustrialLean Thinking é uma filosofia de gestão utilizada mundialmente, cujo objectivo é a eliminação de desperdício e a criação de valor. Na base deste pensamento está o conceito de melhoria contínua, conceito esse que parte do princípio que existe uma evolução gradual conjunta, resultante de procedimentos simples que aos poucos se traduzem em ganhos significativos. Neste relatório, o objectivo é identificar alguns dos desperdícios numa empresa do sector automóvel, para depois, utilizando algumas das mais importantes soluções Lean, apresentar melhorias. São apresentados conceitos que permitem uma melhor compreensão desta filosofia, tais como as técnicas Just-In-Time (JIT), o método SMED – Single Minute Exchange of Die – e conceitos Kaizen. As melhorias apresentadas baseiam-se essencialmente em métodos de eliminação de desperdícios, pelo que a ferramenta que teve mais impacto na implementação do Lean Thinking foi o método 5S´s,que se refere a um conjunto de práticas assentes na organização, arrumação e ordenação do local de trabalho. Todas as melhorias que contribuíram para um aumento de desempenho são demonstradas, bem como alguns dados que permitiram tirar algumas conclusões acerca das reduções nos tempos de setup.
Lean Thinking is a management philosophy used worldwide, whose goal is the elimination of waste and the creation of value. This thought is based on the continuous improvement concept, which means that there is an incremental improvement over time, resulting from simple steps that gradually translate into significant gains. In this report, the aim is to identify some of the waste in an automotive components company, and then, using some of the most important Lean solutions, show improvement in the light of their efficiency. Some of the concepts that allow a better understanding of this philosophy are presented, such as Just-In-Time (JIT), SMED - Single Minute Exchange of Die- and Kaizen concepts. All the improvements presented are based mainly on methods for reducing waste, and the tool that has had more impact on the Lean Thinking implementation was the 5S's method, which refers to a set of practices based on organization, storage and order in the workplace. All improvements which contributed to an increase in performance are reported, as well as some data that helped to draw some conclusions about the reductions in setup times.

Avsikten med denna rapport och undersökning är att belysa vikten av att införa Lean Thinking i företagets alla delar samt hur detta utförs på ett hållbart sätt. Med hållbart menas här att företaget ska ta vara på sina medarbetare och lyfta dem samtidigt som de lyfter verksamheten och effektiviserar processerna. Syftet med studien är att studerar hur Lean Thinking fungerar i kontorsmiljö samt hur en organisation går till väga för att påbörja en hållbar implementering av Lean. Intresset för Lean föddes under kursen Lean Production och sedan dess har vi uppmärksammat fel och problem i mötet med olika företag vilket har motiverat till denna studie. En deduktiv metod har använts och studien grundar sig dels på litteraturstudier, kvalitativa intervjuer, samt en fallstudie som har utförts i samarbete med ett företag som precis har påbörjat sin Lean-resa. I syfte att höja validiteten har en f.d. lean-föreläsaren, Anders Nylund, från Högskolan i Borås intervjuats. I resultatet presenteras respondenternas svar och jämförts med råden och riktlinjerna som kommit fram under intervjun Nylund för att utvärdera om företaget har bra mål och korrekta tillvägagångssätt. Vidare presenteras en guide som i korta drag presenterar hur man ska gå till väga och vad man som företag bör tänka på vid implementation av Lean i kontorsmiljö.The intention of this report and study is to highlight the importance of implementing Lean Thinking in all parts of the company and doing so in a sustainable way. To implement something in a sustainable way is to consider your employees and helping them reach new goals and possibilities and making the business more efficient at the same time. The purpose is to study how Lean Thinking works in an office environment and how an organization initiates a sustainable implementation of Lean. The interest of Lean first started during the course Lean Production and since then we`ve noticed a lot of different problems that companies were having, that we hadn´t see before. This is the motivation for this study. The study is based on a deductive method and is performed through literature studies, interviews based on qualitative methods and a case study performed in association with a company who just recently started their Lean journey. In order to increase the validity of the report we conducted an interview with an former lecturer, Anders Nylund, who works at the University of Borås. The results of the interviews are presented and compared with the advice and the guidelines we gathered from the interview with Nylund to evaluate if the company´s goals and approach are valid. Furthermore a guide is presented that briefly explaines how a company should go about to implement Lean in an office environment.

Full textAbstract:
Despite many significant contributions and advances of lean thinking recorded in articles, books, and industrial case studies, its impact upon the maintenance function has not been fully investigated. From a maintenance perspective, excluding TPM, little or no insight into the use of lean thinking concepts in maintenance can be found in the literature, despite prominent contributors advocating greater management and business integration. An objective of the research described in this thesis was to satisfy the need for industry to understand the contribution of lean thinking to the maintenance of manufacturing systems. A research hypothesis (lean thinking improves the effectiveness of the maintenance function) was therefore devised that aimed to bridge this gap in knowledge in which the researcher developed two new tools alongside existing methodologies for further investigation. The first novel research tool, a lean concept reference framework, was used to comprehensibly represent fe--antfiffikifig concepts possible within a company, and maintenance in particular. Ihe sec n oyýý _411 measure of maintenance performance comprised a number of indicators that sign ough ify c maintenance activity. This was used to reflect the impact of lean concept use by maintenance through change in activity performance. The research investigates the current views of lean thinking and maintenance within the UK, and particularly in the automotive industry. It exposes the diversity of maintenance as a function within this industry, and highlights the scope of lean concept use and understanding. As an outcome of the research, it was found that each company investigated had different reasons for adopting and using lean concepts within their maintenance function. Similarly, each company differed in the management and use of their performance data. Nonetheless, all those investigated accepted the role of lean concept use within maintenance, and considered certain elements useful. These elements were used as an aggregation of tools to assist maintenance in their activities rather than using them to develop an alternative maintenance strategy. However, perception of lean concept use, and the perceived benefits gained differed according to different viewpoints. Although it was generally accepted that lean use bought about or improved overall skills, and helped provide the basis of a more robust and standardised maintenance department, concern was expressed concerning the difficulty in translating essentially lean manufacturing techniques to suit maintenance.

Resumo: A área de tecnologia da informação (TI) atravessou, e continua atravessando, os mesmos desafios de qualquer outra área da indústria. Desafios como: obter bons níveis de produtividades; entender e se aproximar do cliente; reduzir custos; e produzir inovação. Para gerenciar esses desafios a área de TI tem buscado novos mecanismos, por vezes criando práticas e métodos próprios, ou os trazendo de outras áreas de conhecimento. O Lean trouxe para a indústria, primeiramente a automobilística, e depois para várias outras, um novo padrão de produção e qualidade. O Lean questionou os padrões da produção em massa e trouxe novas formas para combater o desperdício, aumentar a qualidade e obter lucratividade no longo prazo. O termo Lean IT é usado para denotar o uso do Lean no combate dos desafios da indústria de TI, e o Lean Software Development é termo usado para uso do lean na área de desenvolvimento de software. O trabalho estuda e aplicada uma ferramenta de avaliação do nível de lean para a área de software, criando um procedimento para aplicação da ferramenta no Brasil. A ferramenta e o procedimento criado foram aplicados em três empresas de Desenvolvimento de Software com diferentes perfis. Os resultados demonstraram a aplicabilidade da ferramenta de avaliação do nível de lean nas empresas selecionadas, foram apontados ajustes e apresentados a necessidade de novos estudos. Também foram revistos os autores do Lean Thinking e do Lean Software Development
Abstract: The technology information (IT) industry has been facing challenges common to any other industry type. Challenges as: achieve good productive level; understand the client need; pressure for cost reductions; and innovation. IT has been searching for solution to address these challenges, sometimes creating own methods and practices, and sometimes, bringing them from other type of industries. The Lean has showed clear benefits and introduced a new standard to the automobile industry and manufacture type of business. Mass production standards were challenged by Lean creating new ways of dealing with quality and productivity. Lean has been positioned as an important alternative to deal with waste, to increate quality and expand long term profitability. The term Lean IT is used on application of Lean to address IT industry challenges, and Lean Software Development the application of lean at software development industry. The research reviews a leanness assessment tool adapted for software industry, developing an adaptation for the application at Brazil software industry. A procedure of application was created and the tool was applied at three different Software companies (enterprises). The results showed that the tool to evaluate leanness at software is applicable at the selected companies, adjustments were need and further studies are required.

Full textAbstract:
This research thesis presents the development of a novel Lean Knowledge Life Cycle (LeanKLC) framework to support the transformation into a Lean Product Development (LeanPD) knowledge environment. The LeanKLC framework introduces a baseline model to understand the three dimensions of knowledge management in product development as well as its contextualisation with acclaimed LeanPD process models. The LeanKLC framework comprises 23 tasks, each accomplished in one of the seven key stages, these being: knowledge identification, previous knowledge capture, knowledge representation, knowledge sharing, knowledge integration, knowledge use and provision and dynamic knowledge capture. The rigorous research methodology employed to develop the LeanKLC framework entailed extensive data collection starting with a literature review to highlight the gap in the current body of knowledge. Additionally, industrial field research provides empirical evidence on the current industrial perspectives and challenges in managing product development knowledge. This research was part of a European FP7 project entitled Lean Product and Process Development (LeanPPD), which provided the opportunity to involve industrial collaborators in action research to support practical aspects during the LeanKLC framework development. The synthesis with the current LeanPD paradigm is accomplished by demonstrating the LeanKLC stages in two distinct streams related to the development of A3 thinking for problem solving and the development of trade-off curves to facilitate set based design at the conceptual stage. The novel LeanKLC is validated in two case studies providing the industry with detailed insights on real product development applications. In particular this research highlights that the LeanPD knowledge environment is a wide subject area that has not yet been thoroughly understood and that industry engagement in empirical research is vital in order to realise any form of LeanPD transformation.

Dissertation (MTech( Mechanical Engineering)--Cape Peninsula University of Technology, 2011Lean thinking and its principles, as described by Womack and Jones (1996) has been successfully applied to the manufacturing and operational environment, as evidenced by associated case studies. Fostered by a rapid spread into many other sectors beyond the automotive industry, there has been a significant development and localisation of the lean concept in general. This research study sets out to investigate the effects of lean thinking on production processes in a Small and Medium Engineering Enterprise (SMEE). It is hoped that the methodology adopted and the results of the study in the form of a concise lean principle model will assist SMEEs in the strategic planning of their manufacturing processes and improve their sustainability. The case described here, where lean principles were adopted at a transformer manufacturing company (referred to as ABZ), was considered a success by most of those involved at the company. The production cycle time improved from 33 days to 4.5 days within a few weeks of the implementation. In addition; product quality, worker morale, and housekeeping also improved drastically.

Mestrado em Gestão e Estratégia IndustrialO objectivo principal deste trabalho prende-se com a avaliação do Sistema de Segurança Alimentar implementado na Empresa ABC, com o intuito de verificar a sua aptidão para o cumprimento dos requisitos da Norma NP EN ISO 22000:2005 - Sistemas de gestão da segurança alimentar - Requisitos para qualquer organização que opere na cadeia alimentar. No sentido de desenvolver e enquadrar este tema, abordaram-se aspectos relacionados com a qualidade, a segurança alimentar, o actual sistema implementado pela empresa - HACCP -, a contextualização da certificação e a ISO 22000:2005. Assim, dadas as perspectivas futuras da empresa em implementar um SGSA com base neste referencial, procedeu-se à realização de um estudo diagnóstico e de uma tabela comparativa para uma análise inicial dos procedimentos a realizar pela empresa. Apesar de não terem sido testados na prática os procedimentos necessários à implementação desta norma, este trabalho constituiu uma importante referência para todos os colaboradores da empresa. Permitiu uma real percepção do SSA implementado e forneceu linhas orientadoras das primeiras acções de melhoria a realizar para a efectiva implementação deste referencial.
The current work aimed to evaluate an existing implemented Food Safety System in the ABC Enterprise, intending to verify its suitability in relation to the achivement of requirements defined by NP EN ISO 22000:2005 - Food safety management systems - requirements for any organization in food chain. To develop this issue, we discussed aspects related to quality, food safety, the current system implemented by the company - HACCP -, the context of certification and ISO 22000:2005. Therefore given the future prospects of the company to implement a Food Safety and Quality Management System based on this standard, we conducted a diagnostic study and a checklist for an initial review of the procedures to be carried out by the company. Although the necessary procedures for implementation of this standard haven't been tested in practice, this work was an important reference for all organization, enabled a real perception of the current Safety Food System and provided guidelines necessary to implement the processes and procedures requested by this standard.

Joint Applied ProjectIn this Joint Applied Project, we study application of lean thinking at White Sands Missile Range, an Army Major Range and Test Facility Base (MRTFB), tasked with developmental Test and Evaluation (T and E) as its primary mission. We interviewed a representative segment of leaders, managers, and working level lean implementers, and surveyed 285 participants in lean events at White Sands. We employed a comprehensive, uniform set of questions in those interviews and surveys to gain insight into significant expectations, questions, issues, concerns, difficulties, constraints, and uniquely governmental situations and circumstance related to this implementation. We organized and analyzed a massive and significant resulting data set around emerging themes including linkage between lean and personnel cuts, management support of lean, small incremental benefit versus large bottom-line impact, process documentation, metrics and measurement, vision, urgency, and goals, uniquely governmental issues, and the lean process itself. We offer relevant conclusions and recommendations, based on those themes, which may significantly aid similar government organization who are currently, or expectantly, engaged in lean implementations or other process improvement efforts. We offer those conclusions and recommendations as academic and neutral examinations of real issues associated with an actual lean implementation. Notwithstanding the difficulties and complexities that we have examined in this study, we find an overwhelming majority of our participants believe there was broad incremental benefit from lean, that its cost was warranted and necessary, and that it absolutely should continue to be used as a tool to achieve greater efficiency, quality, and effectiveness in government business processes.

Matsvinn är ett aktuellt ämne och mycket arbete utförs för att på olika sätt hantera följder av detta. Syftet med denna studie är att studera problemen angående matsvinn utifrån ett lean management perspektiv. Studien är avgränsad till ”ICA nära Bredaryds” kött- och charkavdelning. Genom att identifiera de bakomliggande orsakerna till matsvinn samt undersöka hur grundläggande principer inom lean kan hantera dessa, försöker studien forma långsiktiga strategier i syfte att minska matsvinnet i livsmedelsbutiker.De två huvudorsakerna till matsvinnet som identifierats i studien är variation i kundernas efterfrågan samt variation i personalens arbetsmoment. För att hantera variationen i kundernas efterfrågan bör tankesättet “lean thinking” implementeras. Genom att arbeta med “lean thinking”-cykeln och kontinuerligt eliminera slöseri samt utveckla systemet så att det blir av dragande karaktär kommer kundernas variation att delvis kunna hanteras vilket i sin tur minskar matsvinnet. För att hantera variationen i arbetsmomenten bör standardiserade arbetssätt implementeras. Då all personal arbetar på samma sätt kommer variationen i utförandet av olika arbetsmoment att minska vilket i sin tur genererar ett minskat matsvinn.Nyckelord: Lean,Food waste is today a subject of large interest and a lot of work is currently being done to handle this issue. The aim of this study is therefore to give a contribution to the problem solving in this area from a lean management perspective. The study is limited to “ICA nära Bredaryds” department for cured meat and provisions. By identifying the underlying issues of food waste in connection with investigating how lean principles can handle these, the study aims to form long-term and strategic solutions on how to minimize waste in food shops.The two main causes of food waste that have been identified in the study are the variation in customer demand and the variation in how the staff perform their work. In order for the food shop to handle these two problems, two solutions have been suggested. In order to handle the variation in demand, the mindset of lean thinking should be implemented. By working with the lean thinking cycle and continuously eliminating waste and at the same time develop a pull system the variation in demand can be handled, which in turn will reduce the food waste. To handle the variation in workflow, standardized work methods should be implemented. Directing the staff to work the same way will reduce the variation in how the work is performed, which in turn will generate reduced food waste.

Kostnaden för nyproduktion av hus i Sverige har ökat markant under de senaste åren. Byggföretag har svårt att hålla både projektens löptid och kostnader nere, vilket resulterat i ett ökat marknadspris och ett växande missnöje bland slutkunder. De ökade kostnaderna beror enligt forskning på vanligt förekommande slöseri i form av såväl material som arbetskraft. I försöken att eliminera slöseri har många företag anpassat sin verksamhet efter Lean Thinking, ett system som härstammar från den japanska bilindustrin, bestående av verktyg och metoder med huvudsyfte att identifiera och eliminera slöseri. Ur detta har även nya former av byggnation fångat marknadens intresse. Industrialiserat byggande är en metod som förflyttat stora delar av verksamheten från byggarbetsplats till prefabricering i fabrik och på så sätt eliminerat många av de slöseri och riskmoment som förknippas med det traditionella synsättet på byggnation. Studien lägger fokus på hur arbete med Lean Thinking och prefabricerat byggande kan avhjälpa de kostnadsproblem som branschen ställs inför på dagens marknad. Genom en fallstudie har vi beretts möjlighet att på nära håll studera för- respektive nackdelar med ett prefabricerat byggande, samt fått möjlighet att studera en organisation där verksamheten utgår från Lean Thinking. Studien visar att det genom Lean Thinking och prefabricerat byggande går att minimera vanligt förekommande slöseri inom byggbranschen. Utförandetiden för prefabricerat byggande är också mycket kortare än vid traditionellt byggande och på så vis hålls kostnaderna nere. Genom att ytterliga utveckla prefabricerat byggande enligt Lean Thinking skulle det vara möjligt att i större utsträckning minimera slöseri och möjliggöra ett ännu smartare byggande.The costs of house construction in Sweden have increased conspicuously over the last years. Construction companies have a hard time maintaining low project lead-times as well as keeping costs within the financial plan, which in turn has affected market price and created a growing discontent amongst buyers. Research indicates that the increased production costs are in many ways caused by the large amount of waste, in form of materials and labor, which is common within today’s construction projects. Efforts to eliminate waste has led many companies to adapt Lean Thinking, a system with roots in Japanese car manufacturing industry, containing tools and methods designed to identify and eliminate all kinds of waste. From all this, new ways of construction has been introduced on to todays market. Industrialized housing is a relatively new concept, which has eliminated a lot of waste and risks by moving construction away from an on-site project into prefabrication within factories. This study focuses on how Lean Thinking adaptation and industrialized construction can help lowering construction costs. A case study has given us the opportunity to follow an industrialized construction project up close, as well as the opportunity to study an organization that has implemented Lean Thinking. The study shows that it is possible to reduce common waste within construction industry through Lean Thinking and industrialized housing. The project lead-time for industrialized housing is also much shorter compared to traditional construction methods and therefore the costs are kept low. By continuing to evolve industrialized housing through Lean Thinking it would be possible to further reduce waste and consequently enabling an even smarter way of construction.

This research is motivated by the National Academy of Engineering and the Institute of Medicine's joint call for research in healthcare, promoting the application of principles, tools, and research from engineering disciplines, and complex systems in particular. In 2005, the US healthcare expenditure represented 16% of its GDP, with hospitals representing the largest source of expenditure, as is the case in the United Kingdom. Consequently, the strategies and operations developed and implemented by hospitals have a significant impact on healthcare. Today, it would be hard to find a hospital that is not implementing a Lean initiative or who isn't familiar with its concepts. However, more often than not, their approach has narrowly focused at a process level and inside individual service units like an emergency department. This research seeks to elevate traditionally narrow hospital definitions of lean and explore the broader concepts of lean enterprise principles and Enterprise Architecture (EA) while enhancing our knowledge of hospitals' socio-technical complexity and enriching an emerging EA Framework (EAF) developed at the Massachusetts Institute of Technology (MIT). Following an extensive longitudinal multidisciplinary literature review, a number of expert interviews, and preliminary empirical findings, an exploratory inductive and deductive hybrid study was designed to collect and concurrently analyze both qualitative and quantitative empirical data from multiple hospital settings over two main phases: * The first phase consisted of recorded interviews with the Chief Executive Officers of seven leading Massachusetts hospitals, who also provided sensitive internal strategy and operations documents. We explored how hospitals currently measure their hospital performance and how their explicit and implicit practices may be improved using lean enterprise principles. e The second phase comprised two in-depth case studies of large leading multidisciplinary hospitals, one located in the US and other in the United Kingdom, and included a total of 13 embedded units of analysis. Multiple sources of evidence were collected including electronic medical records, 54 interviews, observation, and internal documents. Findings were categorized and sorted, as phenomena of interest consistently emerged from the data, and enriched both the EAF, and our understanding of hospitals' EA in particular. In both in-depth hospital cases we found that their EA consisted of multiple internal architectural configurations, and in particular, those with an enriched understanding of EA had made decisions which had improved not only their local performance, but also enhanced their interactions with other service units upstream and downstream. Conversely, worse performing configurations demonstrated a limited understanding of their hospital's EA. We conclude that hospital performance can be improved through an enriched understanding of hospital EA. Furthermore, whilst considering all hospitals included in this study, we propose general and specific recommendations, as well as diagnostic questions, performance dimensions, and metrics, to assist senior hospital leaders in architecting and managing their enterprise.

Full textAbstract:
Background: The continued success of Lean thinking beyond manufacturing has led to an increasing interest to utilize it in software engineering (SE). Value Stream Mapping (VSM) had a pivotal role in the operationalization of Lean thinking. However, this has not been recognized in SE adaptations of Lean. Furthermore, there are two main shortcomings in existing adaptations of VSM for an SE context. First, the assessments for the potential of the proposed improvements are based on idealistic assertions. Second, the current VSM notation and methodology are unable to capture the myriad of significant information flows, which in software development go beyond just the schedule information about the flow of a software artifact through a process. Objective: This thesis seeks to assess Software Process Simulation Modeling (SPSM) as a solution to the first shortcoming of VSM. In this regard, guidelines to perform simulation-based studies in industry are consolidated, and the usefulness of VSM supported with SPSM is evaluated. To overcome the second shortcoming of VSM, a suitable approach for capturing rich information flows in software development is identified and its usefulness to support VSM is evaluated. Overall, an attempt is made to supplement existing guidelines for conducting VSM to overcome its known shortcomings and support adoption of Lean thinking in SE. The usefulness and scalability of these proposals is evaluated in an industrial setting. Method: Three literature reviews, one systematic literature review, four industrial case studies, and a case study in an academic context were conducted as part of this research. Results: Little evidence to substantiate the claims of the usefulness of SPSM was found. Hence, prior to combining it with VSM, we consolidated the guidelines to conduct an SPSM based study and evaluated the use of SPSM in academic and industrial contexts. In education, it was found to be a useful complement to other teaching methods, and in the industry, it triggered useful discussions and was used to challenge practitioners’ perceptions about the impact of existing challenges and proposed improvements. The combination of VSM with FLOW (a method and notation to capture information flows, since existing VSM adaptions for SE are insufficient for this purpose) was successful in identifying challenges and improvements related to information needs in the process. Both proposals to support VSM with simulation and FLOW led to identification of waste and improvements (which would not have been possible with conventional VSM), generated more insightful discussions and resulted in more realistic improvements. Conclusion: This thesis characterizes the context and shows how SPSM was beneficial both in the industrial and academic context. FLOW was found to be a scalable, lightweight supplement to strengthen the information flow analysis in VSM. Through successful industrial application and uptake, this thesis provides evidence of the usefulness of the proposed improvements to the VSM activities.

A large number of customers do not make the purchase owing to a series of unmet trends that face the consumer behaviour which leads to significant economic losses and inefficient service. They have therefore focused their efforts on finding impulse mechanisms through allowing them to migrate to less costly processes and/or to achieve better utilisation of available resources without success. This research inquires into the effectiveness of the Lean Thinking Simulation (LTS) model, which consists in the development of a set of methodological phases and the adaptation of the technological support termed as Digital Change to improve the performance of customer service in Peruvian fast food. The main result of this practical study was defined by a Dashboard in real-time, and as a first approximation of the model, a 17.03% improvement can be shown in the performance of customer service on the fast food selected.

The pursuit for an efficient productive process, low costs and higher value added for products and services offered to the customers has become an important feature for companies in various economic sectors in a global perspective. In the service sector, some companies have adopted the fundamentals of Lean Service to eliminate waste in many aspects of their activities aiming better operating results. However, the lack of knowledge in this sector and the low number of research in adoption of Lean Service, require studies on their applicability. This research aimed to check if the Lean Service practices are applied to Information Technology (IT) services activities and if this has brought improvements in operational terms as well as in the quality of services provided. A systematic literature review supported by bibliometrics methods identified just few articles published in this area into literature however this research identified some companies using it in this sector. In an empirical perspective of LS application two case studies present results with evidence of operating performance and quality improvements on LS practices adopted relating the previous environment.
A busca por um processo produtivo eficiente de baixo custo e maior valor agregado aos produtos e serviços oferecidos aos clientes se tornou uma característica importante para empresas de diversos setores econômicos em uma perspectiva global. No setor serviços, algumas empresas adotaram os fundamentos do Lean Service para eliminar os desperdícios em vários aspectos de suas atividades visando melhores resultados operacionais. Entretanto, a falta de conhecimento neste setor e a baixa quantidade de investigações sobre a adoção do Lean Service demandam estudos sobre sua aplicabilidade. Neste contexto, o trabalho buscou constatar se as práticas do Lean Service são aplicadas nas atividades de serviços de Tecnologia da Informação (TI) e se isso trouxe melhorias em termos de desempenho operacional, bem como, na qualidade dos serviços prestados. Uma revisão sistemática de literatura apoiado com técnicas bibliométricas aponta escassez de artigos publicados nesta área na literatura, entretanto um levantamento realizado nesta pesquisa indica sua utilização por diversas empresas do setor. Para uma perspectiva empírica da aplicação do LS, dois estudos de caso apresentam resultados com evidências de melhorias no quesito de desempenho operacional e qualidade em relação ao ambiente previamente às práticas do LS adotadas.

Syftet: Syftet med denna studie är att skapa förståelse för varför onödig efterfrågan uppstår på Telefonbanken. Teoretisk och empirisk metod: Det har gjorts en kvalitativ studie med en abduktiv ansats vilket innebär att vi arbetat med teorin och sedan återvänt till empirin för att se dess betydelse för teorin. Observationer och intervjuer är metoder som används för datainsamlingen. Respondenterna utgörs av bankkunder i en enskild bank som har valts ut med hänsyn till om de varit i kontakt med banken ett flertal gånger med samma ärende. Dessa kunder har vi kunnat identifiera med hjälp utav deltagande observationer. Teoretisk referensram: Studien har till stor del utgått från Lean production konceptet. Det är ett koncept om hur aktiviteter förbrukar resurser men som inte tillför något värde. Lean production fokuserar till stor del på tillverkande företag men kan även tillämpas på tjänsteföretag, detta genom begreppet Lean service. Slutsats: Resultatet av denna studie har varit den upplevde otydligheten och missförståndet kring kommunikationen mellan kunden och banken. Det finns även indikationer på svårigheter att navigera i bankens system. Detta tyder på att den onödiga efterfrågan uppstår på grund av bankens ärendehantering och kommunikation med kunderna.

Lean Thinking has been widely implemented in various industries in the production context. Lately a number of companies in the service sector have developed lean systems within their organisations to improve efficiency, productivity, and quality of their services. In our study we are putting forward an approach for operational excellence using Lean Thinking principals in the public service context. The study was performed at the Swedish Tax Agency and the main process examined was mail-returns handling process, the main goal was to improve business process by eliminating non value adding activities within the mail-returns handling process. A thorough investigation of the Swedish Tax Agency process was carried out, primary (core) business process was identified. We examined the supporting processes and how they can affect the primary process performance, and we defined the activities associated with mail-returns handling process and the costs incurred, which led to having a fact-sheet that examined the entire process. Process mapping for the current state was carried out and Root Cause Analyses was performed. We identified root causes of the problem and process elements with high improvement potential, and we presented an optimisation proposal for the current state. Based on the optimisation proposal, an improvement proposal for the whole process was developed. Some of the notable attributes of this redesigned strategy were substantial cost savings and reduced process time. The proposal was approved by the Swedish tax agency and practical implementation is initiated.

Thesis (MScEng)-- Stellenbosch University, 2013.ENGLISH ABSTRACT: It has been postulated that lean thinking principles can be successfully applied to any industry. Following on that postulation, there have been great advances in the area of lean thinking outside the “traditional” domain of manufacturing. One such advancement has been in the area of maintenance operations where lean thinking has been used through the concept of lean maintenance. However, a problem lies in the fact that the work that has been done so far has been largely limited to the manufacturing environment where lean maintenance is practised as a prerequisite for lean manufacturing. Little evidence exists of the use of frameworks or models that can test, let alone apply, lean thinking in operational maintenance environments outside of the manufacturing context. The main objective of this research was to come up with a framework, based on lean thinking tools and relevant performance measures, which will prove the applicability or otherwise, of lean thinking in an operational maintenance environment outside the traditional domain of manufacturing. A case study of the rolling stock section of the Salt River depot of PRASA, Metrorail, which is a typical non-traditional domain for lean thinking, was used to build and verify the framework. The Analytic Hierarchy Process (AHP) together with the Quality Function Deployment (QFD) process, is used in building and quantifying the judgements made in developing elements of the framework. The Value Stream Management process is used to predict the possible outcomes of using the proposed framework in the case study. The study was based on the hypothesis that lean thinking can also be applicable to non-manufacturing oriented maintenance organisations. The ensuing framework is used to make the argument for the use of the lean thinking approach in non-manufacturing oriented maintenance environments and hence expand the body of knowledge in this subject area. It also provides a roadmap for PRASA, Metrorail and other similar maintenance organisations in the rail industry to streamline and improve current operations through value addition and waste elimination efforts.
AFRIKAANSE OPSOMMING: Daar word bespiegel dat die beginsels van besparende denke (“lean thinking”) suksesvol toegepas kan word op enige industrie. As gevolg van hierdie hipotese is daar groot vooruitgang op die gebied van besparende denke buite die “tradisionele” gebied van vervaardiging. Een sodanige vooruitgang is op die gebied van die verrigting van instandhouding waar besparende denke bekend is as die konsep van “lean maintenance”. Die problem is dat die vooruitgang tot dusver beperk is tot die vervaardigingsomgewing waar besparende instandhouding beskou word as ‟n vereisde vir besparende vervaardiging. Daar word min gebruik gemaak van raamwerke of modelle om besparende denke te toets of om dit toe te pas in instandhoudingsomgewings buite die vervaardigingskonteks. Die hoofdoelwit van hierdie navorsing is om te vore te kom wet ‟n raamwerk wat gegrond is op besparende denke en relevante prestasie maatstawwe, en wat die toepaslikheid van besparende denke , al dan nie, op die verrigting van instandhouding buite die tradisionele gebied van vervaardiging sal bewys. ‟n Gevalle studie van die Soutrivier Depot van PRASA Metrorail, wat tipies is van ‟n nie-tradisionele gebied vir besparende denke, is gebruik vir die bou en stawing van die raamwerk. Die analitiese hiëragiese proses (AHP) tesame met die kwaliteits funksionele ontplooiing (QFD) proses word gebruik in die kies van elemente vir die raamwerk. Die waarde stroom bestuursproses word gebruik om die moontlik uitkomste van die gebruik van die voorgestelde raamwerk, te voorspel. Die studie is gegrond op die hipotese dat besparende denke ook toegepas kan word op nie-vervaarding-georienteerde instandhoudingsorganisasies. Die raamwerk word gebruik om te bewys dat die besparende denke benadering gebruik kan word in nie-vervaardiging–georienteerde instandhoudingsomgewings en dus kennis hieroor uit te brei. Die raamwerk kan ook gebruik word as ‟n padkaart deur Metrorail en ander soortgelyke instandhoudingsorganisasies in die spoorweg industrie, om hulle huidige werksverrigting deur waarde toevoeging te verbeter en om verkwisting te voorkom.

Mestrado em Gestão de OperaçõesTodas as formas de conhecimento são hoje em dia importantes a qualquer sociedade. Deve-se criar condições para que a produção de conhecimento ocorra de uma forma espontânea e natural. Assim como a sua partilha, transferência deve ser acautelada e sem temer.. O conhecimento quanto melhor for trabalhado, cuidado, melhor pode contribuir para as boas práticas de gestão magra. Estas duas áreas se bem trabalhadas promovem a motivação das pessoas e o sucesso de qualquer organização. Prova disso é o sucesso da Toyota. Devemos aprender com os outros, ter uma mente aberta á mudança e a novos desafios. Podemos aprender muito com quem já provou que era capaz, como o Japão e em particular a Toyota, com o seu sistema de produção. Se todos trabalharmos em equipa com espírito de missão poderemos alcançar a excelência operacional, para isso é necessário que todo esse processo se desenrole numa base de confiança mútua e humildade e partilha de conhecimento.. É esta a grande lição de humildade que devemos todos seguir. Uma sociedade pode crescer e alcançar o sucesso se aplicar estas duas áreas de conhecimento correctamente. ABSTRACT: All the kind of knowledge is today very important to the society independent from witch area. We should create conditions to the knowledge production occur in spontaneous and natural scenario. Also to share, transfer without fear. The knowledge need to be very well worked, cared to contribute to the best practices of Lean management. Those two areas if well integrated and under stable can promote the motivations between people and guaranty the success of the organization. The prove that is the success that Toyota have, is the best example how the companies should work the knowledge and the lean management. We need to learn with others, with their best practices, to be an open mind and to the new challenges. We can learn a lot with the best practices of Japan and in particularly with Toyota with there own production system. We can achieve the Excellency. If we can work as a team with a mission spirit. To do so, it is that all of the process flow in a mutual growth based on a mutual trust society. We should admire the humility lesson from Japan and in particular with Toyota. One society can growth and achieve the success if use those two knowledge areas correctly.

The computerization of enterprise electronic business (e-business) remains popular so far. Most of the enterprises hope to adopt the electronic business to support their operation and to strengthen their competences. However, the enterprises are facing the expensive and complicated electronic system as well as the high failure rate of implementing electronic business. To further examine the failure rate, there are three reasons for the failure. First, implemented unsuitable software and caused a huge gap from expected goal. Second, there are shortage of overall goal and systematic plan. Departmental system blocking the information sharing and many isolated island were created. Third, the myth of fitting operations to software and devoting resources blindly, therefore, there is no succeed and face the dilemma. There are tremendous unreasonable and wasting activities when adopting e-business for many enterprises with inefficient performance. Therefore, this paper aims to utilize the lean thinking concept “eliminate waste, create value” to examine the process of e-business in enterprises. Further, it develops a different electronic implementing model. This new model is expected to be able to find the uncertain factors in enterprises and reduce uncertain effects to create values to e-business implementation. The field studies indicate that there are great deals of problems in current e-business implementing models. This study provides a lean thinking model that can solve each problem step by step and has been recognized by studied companies. Thus, the new model of combining lean thinking concept and e-business can excel the e-business system implementation as well as improve adopting efficiencies. This paper also clarifies the inefficiency of enterprises’ e-business implementation. It also builds up a consolidated model for enterprises. This is not only meaningful academically, but also a significant reference for enterprises.

Dissertação de mestrado em Gestão de Projetos de EngenhariaEsta dissertação foi elaborada no âmbito do Mestrado em Gestão de Projetos de Engenharia, da Universidade do Minho e teve como principal objetivo melhorar a proposta de valor, a relação com o cliente e os processos da empresa HAP através da integração da filosofia Lean Thinking com a abordagem Lean Startup. A filosofia Lean Thinking permite combater os desperdícios presentes nos processos da empresa, e desta forma, aumenta a produtividade e a qualidade, reduzindo custos. A abordagem Lean Startup suporta a criação de negócios e produtos de elevado potencial de sucesso e ajustados ao mercado no menor tempo possível. Para realizar esta dissertação recorreu-se à metodologia de Investigação-Ação, tendo-se na primeira fase da metodologia diagnosticado a prestação de um serviço pela empresa pouco desenvolvido e sem a capacidade de criar uma solução que fosse ao encontro das necessidades do cliente. De facto, foi possível confirmar que os processos do negócio da HAP eram constituídos por desperdícios que representavam custos para a empresa e defeitos para o cliente. Neste sentido, depois da análise inicial aos processos da HAP, recorrendo-se a ferramentas de diagnóstico, nomeadamente, o Value Stream Mapping (VSM), foram apresentadas e implementadas propostas de melhoria para reduzir os desperdícios identificados e gerar um serviço capaz de satisfazer as necessidades dos clientes. Estas propostas passaram pela aplicação de ferramentas, nomeadamente, 5S, 5S eletrónico, sistema à prova de erro e trabalho padronizado. Ao nível da abordagem Lean Startup foi implementado o conceito de Produto Mínimo Viável (PMV) para recolher o feedback do cliente acerca do serviço da HAP, criando a oportunidade de melhorar o PMV. Com a aplicação destas ferramentas foi possível reduzir os custos na gestão de operações da HAP, nomeadamente, na atividade de arrendamento diminuíram em 21,6% correspondendo a uma poupança de 160,63€/mês e na atividade de alojamento local em 2,8% correspondendo a uma redução de 370,5€/mês. Na gestão financeira atingiu-se uma diminuição de 100% nos custos que correspondeu a 35€/mês. Quanto à satisfação dos clientes também foram alcançados resultados bastante positivos, destacando-se a avaliação ao serviço HAP que passou de 3,4 valores para 4 valores numa escala de 5.
This dissertation was elaborated under the master’s degree in Engineering Project Management, from University of Minho, and had as main objective to improve the value proposition, the relationship with the client and the processes of the HAP company through the integration of the Lean Thinking philosophy with the approach Lean Startup. The Lean Thinking philosophy allows you to reduce the waste in your company processes, thereby increasing productivity and quality while reducing costs. The Lean Startup approach supports the creation of businesses and products with high potential of success and adjusted to the market in the shortest possible time. The action research methodology was employed throughout the development of this dissertation. In the first phase of the methodology, was diagnosed the undeveloped service of the newly established company, unable to create a solution that met the clients’ needs. In fact, it was possible to confirm that the business processes of HAP featured wastes which implicated costs for the company and defects for the client. In this sense, an initial analysis of HAP´s processes using diagnostic tools, namely the Value Stream Mapping (VSM), led to the implementation of improvement proposals which meant to reduce the identified wastes and generate a service capable of meeting the client’s needs. These proposals included the application of tools, namely, 5S, 5S electronic, Poka-Yoke and standardized work. At the level of the Lean Startup approach, the Minimum Viable Product (MVP) concept was implemented to gather customer feedback about HAP´s service, creating the opportunity to improve the MVP. With the application of these tools it was possible to reduce the costs in the management of HAP´s operations, namely the renting activity which decreased by 21.6% corresponding to a saving of 160,63€/month, and the local housing activity decreased by 2.8% corresponding to a reduction of 370,50€/month. As for the financial management, a reduction of 100% in costs was achieved, which corresponds to saves of 35€/month. In terms of customer satisfaction, very positive results were also achieved, with emphasis on the evaluation of the HAP´s service, which went from 3.4 to 4 on a scale of 5.

Lean Thinking is a methodology or management philosophy. It can be valued by the customer’s viewpoint to determine which activities are value-adding. Utilizing Lean Thinking can eliminate unnecessary activities and simplify production processes. Furthermore, it can accelerate production process and improve product quality. Continuous revising and developing procedures can promote the production efficiency and customer requirement. Lean Maintenance is quite different from the traditional Maintenance. In this research, the principles of Lean Thinking, Value Stream Mapping Analysis and Lean Technique were applied to establish Lean Maintenance Model. The revised Lean Maintenance Model is demonstrated as a better methodology in a case study of Intermediate Maintenance Depot.

JEL Classification System: M110 – Business Administration: Production Management; H70 – Public Economics: State and Local Government.Efficiency and effectiveness of services provided by public organisations have impact in customers’ satisfaction. The current research has as main goal to analyse if lean tools create efficiency and effectiveness gains when applied to a specific set of processes from a public service. Accordingly, lean thinking background is considered. The methodology adopted is based on a case study developed in the Education Department of the city council of Arruda dos Vinhos. Direct observation and informal interviews with staff members and customers are performed. Three processes are analysed using Value Stream Mapping (VSM) tools: application for free school meals for students who apply for social benefits, application for “home-school-home” transport allowance, and money refund from transport expenses. The lean tools used are the VSM big picture map, process activity mapping, and spaghetti diagram. Processes’ customers are identified and what they consider value is assessed. Wastes are identified and suggestions for improvement are developed. Findings show that gains in effectiveness are expected if the suggestions provided are implemented, the process would be more accurate and the outcome would be obtained sooner and without mistakes resulting in more value for customers; regarding efficiency, based on the elimination of waste processes’ total times reduction is expected in the three cases (useful time can be reduced by 29% in the first process, 47% in the second, and 34% in the last one), less human resources’ time is required and shorter distances are covered.

The following work demonstrates the application of lean in a logistics company, answering the following question: “How can lean improve the logistics company’s processes?”. To answer the introduced question, a literature review was conducted, a documental analysis, direct observation and semi-structured and unstructured interviews were carried out. After that being completed, different lean recommendations were suggested to reduce or even eliminate wastes in the company. Some of the tools suggested were poka-yoke, cellular layout, kaizen and visual management. It wasn’t possible to verify the efficiency of the suggested tools since the investigation was done during the pandemic scenario, which enabled the author to spend more time in the company and due to the short time of the internship. As a future investigation, it is proposed to consider all the suggestions proposed, hire at least one lean specialist to explain to the employees what is lean and why it is so beneficial, and to switch to a digital workplace environment like Microsoft 365.O presente trabalho demonstra a aplicação da metodologia lean numa média empresa (ME) de logística portuguesa. Neste trabalho procurou-se responder à questão “Como é que o lean pode melhorar a gestão dos processos de uma empresa de logística?” Para tal foi realizada uma revisão bibliográfica, análise documental, observação direta e entrevistas semi e não estruturadas. Posteriormente, diferentes recomendações lean foram sugeridas, para reduzir ou até eliminar os desperdícios na empresa em questão. Algumas ferramentas sugeridas foram poka-yoke, layout de células, kaizen e gestão visual. Não foi possível verificar a eficiência das ferramentas sugeridas uma vez que a investigação em causa foi realizada durante o cenário de pandemia, o que impossibilitou ao autor permanecer mais tempo na empresa e também devido ao tempo relativamente curto do estágio. Para investigação futura, sugere-se considerar todas as sugestões propostas, contratar pelo menos um especialista lean de forma de explicar aos colaboradores o que é o lean e porque é que é tão benéfico e, por último transitar para um ambiente de trabalho digital como por exemplo o Microsoft 365.
