Full textAbstract:
Design for Six Sigma (DFSS) is a further development of the Six Sigma draft to carry through preventing quality measures in developing and designing of new products and processes. With increasing demands on enterprises development processes to be more safety and faster the need of DFSS arise as a product, process and service development concept in the organisations. Design for Six Sigma aims to improve and structure the development process of an organisation and consider the application of the innovation problem solving. The concept aims to leave the structure of the traditional Six Sigma concept and instead, from an innovative perspective, search for new solutions to existing problems. The concept constitute of a toolbox with a lot of quality tools that are divided into phases in a development model. Combined with the organizations project model the Design for Six Sigma concept can give rise to excellent results in the work with developing and designing of new products and processes. The condition to succeed is that the draft has been established and accepted with the organizations collaborator. This thesis work summarizes the contents of the Design for Six Sigma concept. The concentration of the performance has been the underlying theory behind the DFSS draft together with the contents of the methodology and the included tools.Design for Six Sigma (DFSS) är en vidareutveckling av Sex Sigma-konceptet för att genomföra förebyggande kvalitetsåtgärder vid ny- och vidareutveckling av produkter och processer. Med ökade krav på säkrare och snabbare utvecklingsprocesser hos organisationer uppkommer ett behov av detta produkt-, process- och tjänsteutvecklingskoncept. Design for Six Sigma konceptet behandlar strukturering och utveckling av en verksamhets utvecklingsprocess och handlar mycket om applicerandet av det som vanligen benämns innovativ problemlösning. Konceptet syftar således till att frångå Sex Sigmas traditionella strukturerade arbetssätt och istället, utifrån ett innovativt angreppssätt, söka fastställa helt nya lösningar på ett problem. Konceptet består av en verktygslåda med kvalitetsverktyg uppdelade i faser i en utvecklingsmodell. Kombinerat med en organisations projektledningsmodell kan Design for Six Sigma medföra goda resultat vid produkt och processutvecklingsarbete under förutsättning att förståelse och acceptans hos medarbetarna etablerats. Detta examensarbete sammanfattar innehållet i Design for Six Sigma-konceptet. Fokus har legat på DFSSs bakomvarande teorier vilka utgör grunderna till konceptet samt dess innehåll och verktygslåda.

Este presente trabalho visa avaliar a aplicação da metodologia Design for Six Sigma (DFSS) ao processo de desenvolvimento de veículos (PDV) visando atingir níveis de qualidade Seis Sigma quando do início do processo de fabricação. Na verdade, quando se fala em fabricar produtos que já nasçam com níveis de qualidade Seis Sigma, não significa que seja mandatório que se obtenha a honrosa relação de 3,4 defeitos por milhão de oportunidades, mas sim que proporcionem resultados positivos em relação à melhoria da qualidade, otimização de custos, redução do tempo de desenvolvimento, vislumbrando o mais importante de todos os aspectos: o total entusiasmo do cliente. Para tanto, quando se fala da aplicação do DFSS no âmbito do desenvolvimento de veículos, o panorama deste contexto torna-se relativamente mais amplo e complexo, face ao nível de desenvolvimento tecnológico deste setor. O assunto é introduzido descrevendo-se o processo de desenvolvimento de veículos em sua abordagem atualmente difundida, alicerçada por um processo bem definido e estruturado, para se poder introduzir o DFSS neste processo. Antes, porém, introduz-se toda a metodologia referente ao Seis Sigma, por ser o fundamento base para a criação do DFSS. Por fim, a colocação de um estudo de caso procura relatar a aplicação da metodologia DFSS aplicada especificamente para a GM, procurando relatar a estratégia da aplicação, bem como seus principais ganhos alcançados.This present work aims to evaluate the application of the Design for Six Sigma (DFSS) methodology to the vehicle development process (VDP) seeking to reach Six Sigma quality levels when the beginning of the production process. Actually, when it is spoken in manufacturing products that are already born with Six Sigma quality levels, it doesn\'t mean that it is mandatory that must be obtained the honorable relationship of 3,4 defects per millions of opportunities, but that provide positive results in relation to the quality improvement, costs optimization, reduction of the development timing, glimpsing the most important of all of the aspects: the customer\'s total enthusiasm. For that, when it is spoken about the application of DFSS in the extent of the vehicles development, the scenery of this context becomes relatively wider and complex, face at the level of technological development of this section. The subject is introduced being described the vehicles development process in its approach currently spread, found by a very defined and structured process, to allow introducing DFSS in this process. Before, however, the whole methodology regarding Six Sigma is introduced, for being the foundation base for the creation of DFSS. Finally, the placement of a case study tries to demonstrate the application of the DFSS methodology applied specifically for GM, trying to report the strategy of the application, as well as their main reached benefits.

Full textAbstract:
The modern manufacturing world has been driven to compete in a more international and interconnected system. This has led to increased focus upon frameworks and architectures to guarantee quality, high market acceptance, and reduce cost. Modern manufacturing design processes evolved largely from Henry Ford at Ford Motor Company, and Alfred Sloan at General Motors. Their structures embody two different focuses on quality and value engineering which have influenced many recent design frameworks. In the 1970s a heavy emphasis was placed upon Design for Manufacturing, which uses group technology, commonality of processes, and continual focus to reduce part count. Some companies have desired a design process that better accounts for new market needs and Voice of the Customer changes, allowing them to break out of the old processes by using a new framework called Design for Six Sigma. Contextual and survey analysis contrasting DFSS and DFM showed these systems have different definitions of what creates value; which causes a different focus on how to improve value. As the market frequently errs at knowing when to apply DFM or DFSS, using a simple case study of a product with high part and assembly cost, teams were challenged to create a better flashlight using both DFM for part reduction, and DFSS for function improvement. The aim was to increase value. Value has been defined by the formula: value = (performance + capability) / cost or as value = function/cost. Results from the case study combining DFM and DFSS constructs demonstrate a total value engineering construct. It was also shown that DFM indicated effectiveness for a slow-changing market with cost reduction focus, and DFSS demonstrated effectiveness for analyzing continually changing market needs. Disruptive innovations can replace a formerly lull market, for which DFM can be completely unprepared; while DFSS is not effective in slow product-change markets. Incorporating the best of DFSS and DFM creates a Total Value Engineering framework.

No início deste trabalho foi realizada uma detalhada revisão da literatura na qual ficou evidenciado um aspecto frequentemente apontado por praticantes do Design for Six Sigma (DFSS): a necessidade de um roteiro padrão mais prático e intuitivo que possa ser usado na condução de diferentes projetos para o desenvolvimento de novos produtos ou serviços no meio industrial. O trabalho visa, portanto, preencher esta lacuna na literatura ao trazer uma abordagem diferenciada para projetos DFSS. Na abordagem proposta, as principais ferramentas necessárias para o desenvolvimento de um projeto DFSS completo são: o desdobramento da função qualidade (do inglês, Quality Function Deployment – QFD), cujo modelo das quatro fases foi adaptado às necessidades do trabalho, o Delineamento de Experimentos (do inglês, Design of Experiments – DOE) para priorização de fatores e a Simulação de Monte Carlo (SMC neste trabalho) para o estudo dos limites de operação. Cabe ressaltar que a quantidade de ferramentas da qualidade a serem estudadas em um treinamento voltado para projetos DFSS foi reduzida de dezenas a apenas três principais, que podem também ser auxiliadas por outras ferramentas, dependendo das particularidades de cada projeto e caso haja necessidade. Desta forma simplificou-se a implementação do DFSS, dando condições para que o treinamento em DFSS seja mais focado e avançado sem deixar de ser abrangente em termos de área de aplicação. Sendo uma junção do QFD, do DOE e da SMC, a abordagem proposta recebeu o nome de DFSS-QDMC e foi desenvolvida a partir dos roteiros de implementação do DFSS mais citados na revisão da literatura. Neste trabalho de tese, a abordagem DFSS-QDMC é detalhada e sua funcionalidade é ilustrada, descrita matematicamente e comprovada a partir de um teste piloto e de aplicações reais. O teste piloto foi desenvolvido em uma disciplina eletiva oferecida para alunos da graduação na Universidade Federal de Itajubá (UNIFEI) e as aplicações reais foram desenvolvidas ao longo dos últimos anos em parceria com empresas brasileiras de grande porte, durante a condução de treinamentos Green Belt. Os métodos de pesquisa usados na condução deste trabalho foram Modelagem e Simulação no desenvolvimento da abordagem proposta e Pesquisa-ação na implementação desta em casos reais.

Full textAbstract:
Curricula assessment is an integrated process to assist higher education institutions in addressing the challenges in a designated field of study and in exploring the opportunities to better educate and prepare their students for an increasingly complex world. Although assessment as a topic has been researched extensively, there has been a lack of quantitative tools that address the requirements of many of the stakeholders that may be critical to the curriculum design and assessment processes. This research proposes the utilization of Design for Six Sigma (DFSS) to develop a quantitative model for curriculum assessment and improvement for higher education institutions. A review of the literature indicates that there is a lack of
quantitative tools that enhance the reliability and efficiency of gathering customer requirements for curriculum in higher education environment. In addition, there is a lack of tools to translate these requirements into actual characteristics that can be used for curriculum design and assessment purposes. The literature also indicates that curriculum assessment is one of
several educational processes that affect the quality of education. This research proposes a quantitative model for curriculum assessment and improvement in higher education institutions, utilizing design for six sigma methodology. The proposed model explores the use of the Kano model concept to translate needed requirements into desirable curriculum attributes and the general concept of establishing transfer function to determine the level at which those requirements have been satisfied. The use of the developed model can help improve student learning and provide curriculum stakeholders with timely feedback about the curriculum and identify areas in need of improvement. To validate the capability of the proposed model, an ABET accredited department of Industrial Engineering in a US university was used a case study.Ph.D.

Full textAbstract:
The literature suggests that organisations which have adopted Six Sigma have realised that upon achieving a Five Sigma level the only way to surpass this is to redesign the process(es) by means of Design for Six Sigma (DFSS). For others, the selection of Six Sigma over the DFSS approach is not a definitive question and just a guideline can be provided. A major objective of this research was to extend the selection of the requisite Six Sigma approach beyond the sigma level case and the general guidelines, towards a multi-criteria decision using established techniques. Thus, two research questions were defined: what influences the selection of the requisite Six Sigma approach, i. e. Six Sigma versus DFSS? and, how effective is the use of Multi-Criteria Decision Analysis (MCDA) techniques in the selection of the requisite Six Sigma approach? An action research methodology was applied where one Six Sigma project, one DFSS project and one Six Sigma project applied in a non-manufacturing process were implemented and analysed in collaboration with 3M Corporation, General Domestic Appliances (GDA) and Land Rover. From the action research spiral it was concluded that the sigma level has a positive association with the selection of redesign or improvement efforts within Six Sigma, however the Five Sigma level cannot necessarily dictate the use of one approach over the other. Besides the sigma level the selection of the requisite Six Sigma approach is influenced by multiple and conflicting criteria. In addition, the selection can occur at different stages of the methodologies. To assist decision-makers in organising, synthesising and optimising the criteria affecting this decision, the Stochastic Analytic Hierarchy Process (SAHP) was developed and applied to the problem at hand. The SAHP was developed on the basis of Analytic Hierarchy Process (AHP) and disparate sources of relevant literature. SAHP provides a mechanism for achieving a more effective selection of the requisite Six Sigma approach in the form of considering multiple and conflicting criteria using quantitative and qualitative information under uncertainty. In contrast to the traditional AHP, SAHP incorporates probabilistic distributions to incorporate uncertainty that people have in converging into a Likert scale their judgments of preferences. The vector of priorities is calculated using Monte Carlo simulation and the final rankings analysed for rank reversal using statistical analysis with managerial aspects introduced systematically. The concept and implementation of SAHP is new to the selection of the requisite Six Sigma approach and as such it constitutes the main innovation to result from this research. It extends the selection of the requisite Six Sigma approach towards a systematic multi-criteria decision considering multiple and conflicting criteria under uncertainty. Furthermore, while SAHP was originally conceived as a specific aid to the improve or redesign issue within Six Sigma, this research indicates that it is potentially much more widely applicable. This research also provides evidence of how different factors affecting the selection of requisite Six Sigma approach were considered. Further areas of research include the use of a positivist method in order to increase the sample size of the research and identify different factors affecting the decision improve or redesign. The development of SAHP software and extending the SAHP practice to different multi-criteria decisions are also potential areas for further research.

Full textAbstract:
Six Sigma was developed in 1980s in manufacturing industry and became popular as a process improvement method. However, the adoption of this concept is new in construction industry and the aim of this study is to evaluate Six Sigma as a process improvement method within construction context. This thesis includes Literature Review and three interviews. Literature Review had discussed process improvement methods used in construction industry and analyzed the basic features and principles of Six Sigma. Three interviews were conducted about the basic principles of Six Sigma and Quality Concept. Interviewers are a Project Manager, Field and Cost Engineer. The approach of the interview to Six Sigma is based on quality, performance and management aspects. This study defends that there is no doubt about the positive effects of Six Sigma on construction projects. Particularly, Six Sigma can provide a broader quality concept, detailed performance measurement, coordinated and repeatable process/performance improvement. It has increased quality directly/indirectly and has positive effects on production efficiency. As a 2 management approach, Six Sigma is discussable within construction context due to differences of manufacturing and construction industry. Since construction industry includes lots of unrepeatable tasks and different process design techniques, Six Sigma does not seem applicable as a whole management approach in construction industry. Furthermore, it can be integrated to the existing management procedures of companies. Taking everything into consideration, it is obvious that Six Sigma has a lot in order to accelerate fundamental and cultural challenges construction industry needs.

Full textAbstract:
The role of quality control is to correctly translate customers´ requirements into materialized products to achieve customers’ satisfaction. Today Product Development Process (PDP) becomes the stage to improve and to obtain successful products. In the 1980s, Six Sigma appeared as an attempt to improve some aspects of products and services in order to reduce failures in production as much as possible. But there still was a lack of customer perspective over product development project. This thesis approached the lack of customer insight with a new product development process, Design for Six Sigma (DFSS). Examples that describe how DFSS works and its implementation are still missing, therefore the purpose of this master thesis is to prove if the implementation of DFSS would be efficient, effective and closer connected to the customer of mass- production companies. DFSS is based on processes, roles and tools. However, it is questionable whether the suggested role structure and a uniformed process are able to implement in the real world. The methods used for this research project were two interviews with two mass customization companies, qualitative data collection and finally analyzing the collected data by comparing them with the theory of DFSS. This PDP ensures the track, and enhances creativity and innovation, taking the process beyond its capabilities. Moreover, the conclusions of the thesis show that there is no need for a uniformed model, making DFSS more useful and trickier for competitors. The lack of a uniformed model allows to overcome the innovative ability. The skills to reach these roles and the creation of a team within the company are more important than roles and backgrounds themselves. In spite of knowledge of expertise areas, the task is more related to control the collaboration, communication and flow of information within the group. DFSS becomes a successful solution for customer insight, a good combination of tools and techniques. But it does not mean that implementing accurately a certain methodology is the right solution.

The purpose of this research was to develop a composite flooring system to be used in the equine surgical unit in the College of Veterinary Medicine at North Carolina State University. This material was developed due to an extensive need for a new flooring system that would accurately meet the needs of the customers and stakeholders involved. Research included the origin of Design for Six Sigma (DFSS), tools that differentiated it from previous design processes, past/present flooring solutions, structure/dynamics of a horse, horse tendencies, and composite theories. By implementing the five step procedure of DFSS, Define, Measure, Analyze, Design, and Verify, a sound product was able to be realized. Certain DFSS tools were implemented such as Voice of the Customer Analysis, Reverse Engineering, Brainstorming, Design of Experiment, Pugh Concept Analysis, Computer Aided Design, and Finite Element Modeling. The end solution was a composite flooring system that meets the needs of not only the primary market but many secondary markets as well.

Design for Six Sigma (DFSS) is a commonly adopted method for designing a product with a high level of quality, starting with the design of the product or process, so that it is designed or planned without error, without the need of improvement in subsequent stages of the product development process (PDP). The objective of this work is to suggest a framework for the application and implementation of DFSS in PDP. The research method adopted was divided into two stages. First, a systematic bibliographic review was done and afterwards, the theoretical framework developed was evaluated in a large company that uses the DFSS method for more than three years. The main characteristics of this framework developed and evaluated are: the synthesis of specific methods and tools for the application and implementation of the DFSS in the PDP, following the step by step of the DMADV model of the DFSS with the description of the main objectives of each phase of the method. The results of the research presented that the use of the DFSS finds some barriers, and verified that not all tools of the method are used in organizations because they are too complex. The work presents a new framework based on the analysis of the organization with the tools and methods applied by this company.

Full textAbstract:
Design for Six Sigma (DFSS) is a methodical quality design strategy for deploying new products, services, and processes in all aspects of business functions; its goal is to improve customer satisfaction, sales, and revenue.
This project presents the theory and application of the DFSS Define, Measure, Analyze, Design, and Verify (DMADV) model as applied to the design and development of an environmental compliance process. This model addresses recent European Union (EU) regulations known as REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals).
The project presents the methodical use of applicable quality tools and concepts by a project team at an original components manufacturer (OCM) for each stage of the DMADV model. The final presentation has resulted in a process that consistently meets customer requirements, targeted release dates, and process capabilities as defined by the project charter.

In today's aggressive business environment, many manufacturing firms are searching for new strategies or methodologies that will provide some type of competitive advantage. Recently, in order to address that issue, the automotive industry has adopted the process of Design for Six Sigma (DFSS). Based upon the philosophies of Six Sigma quality management, Design for Six Sigma focuses on the design and research phases of product design, as its name implies. Consequent to accurately identifying the customer requirements, the Design for Six Sigma process insists upon data-driven design decisions coherent with the consumer defined quality metrics. While the concepts of Design for Six Sigma and Six Sigma in general have been very successful for a number of large manufacturing firms such as General Electric and Motorola, it is not clear whether it will offer the same benefits for the automotive industry. Using the Parallel Hybrid Truck Program at General Motors Corporation, the largest US automotive manufacturer, as a case study, the implementation of Design for Six Sigma within the automotive industry is explored. It is obvious Design for Six Sigma will provide both advantages and disadvantages. Therefore, in order for Design for Six Sigma to be successful in the automotive industry, the following insights need to be captured and delivered upon. Leadership must be strong and demonstrate a consistent commitment to the process. Both the technical and cultural elements of the process need to be implemented successfully. Integration of Design for Six Sigma needs to occur with current improvement efforts, and coordination of efforts between various groups in the organization needs to exist Interestingly, these are classical problems facing the automotive industry for many years now, and they require a complete paradigm shift from the current automotive practices in order to be successful. Furthermore, to better substantiate the impact of Design for Six Sigma, the following improvements to the standard Six Sigma practices and strategy are recommended. A high level manufacturing position should be created to compliment the product engineering representative for the DFSS process. In addition, DFSS projects should be encouraged from the Manufacturing Organization to create buy-in and to leverage their day-to-day understanding of the product issues. Finally, like product specifications, Design for Six Sigma specifications should follow a product through the design cycle.

Recently, in the United States and worldwide, the excellence of soft skills competencies among entry-level employees has become a priority task of education. Construction employers are encountering a significant gap between the soft skills possessed by the entry level construction graduates and those needed by construction employers, thereby becoming a major challenge for both industry and academia. This research proposed a soft skills instructional curriculum that aims to increase cultivation of soft skills among construction students by exploring the soft skills needed in the construction industry and improving the soft skills educational tools in construction schools. Moreover, the research will answer broad questions such as: Which soft skills matter the most? What is the magnitude of the soft skills gap? And, how do students get help to cultivate soft skills?
A stakeholders-driven exploratory embedded mixed-design research approach was adopted utilizing Design for Six Sigma (DFSS) framework. The DFSS framework is comprised of five phases: Define, Measure, Analyze, Design, and Verify. Therefore, the research defined and organized the construction related soft skills into 12 clusters. The 12 clusters were used to benchmark the soft skills clusters performance among construction graduates using a survey instrument. Simultaneously, the research identified 40 instructional strategies and then defined the relationships between each soft skills cluster and the 40 instructional strategies using structured interviews with experts from academia. The survey data was used to measure the gap in each skill cluster using Gap Score Method and prioritize them into four sets: Critical Clusters, Ideal Clusters, Lowest Priority Clusters, and Least Clusters. Then, the research implemented four Quality Function Deployment matrices using the data acquired from the survey, structured interviews, and the analysis. The four matrices were used to develop a soft skills instructional curriculum comprised of four instructional models in which each soft skills clusters set was matched with the effective instructional strategies. Finally, the research added the values of Gap Score and the value of Sigma Level for each cluster to the proposed curriculum to be used as indicators to measure the future changes in the industry's soft skills need. The proposed curriculum was shared with four experts from academia and they verified the results.
It is expected that the research results will pave the road for launching any future soft skills initiatives in construction education. They revealed significant evidence of the existence of soft skills gaps among construction graduates and proposed an effective soft skills instructional curriculum. It is expected that through utilizing this curriculum, the teaching activities of construction will improve and broaden the soft skills taught in the classrooms to correlate with those needed in the marketplace. Consequently, this will help bridge the gaps between construction graduates and their employers and ultimately facilitate the recruitment of construction graduates.Ph. D.

Full textAbstract:
Lean Six Sigma is a method used to improve the quality and efficiency of processes by reducing variation and eliminating wastes (non-value added activities) in an organisation. The concept of combining the principles and tools of Lean Enterprise and Six Sigma has been discussed in the literature. The majority of Lean Six Sigma applications in private industry have focused primarily on manufacturing applications. The literature has not provided a framework for implementing Lean Six Sigma programmes in non-manufacturing or transactional processes like those in the Entertainment Media industry. The Saudi Broadcasting Corporation (SBC), like many other industries in Saudi Arabia, has high occupational safety risks, such as electric, fire and fall hazards which often occur in the media workplace. These risks are considered very costly and affect productivity and employee morale in general. The main objective of this research is to provide a synergistic approach to integrating occupational health and safety programmes and Lean Six Sigma tools using the DMAIC (Define-Measure-Analyse-Improve-Control) problem-solving method to strengthen and assure the success of safety programmes in the Saudi Broadcasting Corporation (SBC). This research identifies the roadmap (i.e. activities, principles, tools, and important component factors) for applying Lean Six Sigma tools in the media industry. A case study addressing the safety issues that affect employees’ performance within the Saudi Broadcasting Corporation (SBC) TV studio is used to validate work outlined in this research. Furthermore, the Bayesian Belief Networks (BBN) method is used to understand the probability occurrence of safety hazards. The application of the Taguchi Experimental Design method and other Lean Six Sigma tools, such as Cause and Effect diagrams, Pareto principles, 5S, Value Stream map, and Poka-Yoke have been incorporated in to this research. The application of Lean Six Sigma DMAIC problem-solving tools resulted in significant improvement in safety within SBC. The average electrical hazard incident decreased from 2.08 to 0.33, the average fire hazard incident decreased from 1.25 to 0.08, and the average fall hazard incident decreased from 3.42 to 0.17. The research has important implications for the company and its employees, with positive outcomes and feedback reported by top management, the senior technicians, and experts. The research improved the safety by reducing electrical, fire and fall risks. The Safety training sessions are one of the most significant factors that improve their safety awareness. It is observed that Lean Six Sigma problem-solving tools and methods are effective in the Saudi Broadcasting Corporation (SBC).

Full textAbstract:
The complexity of sustainable building maintenance environment requires managers to define and implement appropriate quality benchmark system suitable for this function. Lean Six Sigma (LSS) is one of the most effective process improvement and optimization philosophy that maintenance organisations can implement in their environment. However, literature review has shown that 90% of failures in LSS implementations are due to lack of readiness to change, the unawareness of the required benchmark organisation capabilities, and improper control of priorities. The contribution of the current research approach is in developing a hybrid Knowledge-Based (KB)/GAP/AHP System, consisting of three stages (Planning, Designing and Implementation) and containing over 2500 KB rules. The KB System can assist the decision-makers in identifying the obstacles behind the organisation readiness to change into a benchmark LSS maintenance environment. Thus the KB System will be used to achieve benchmark standards by determining the gap existing between the current environment and the benchmark goal, and then suggest a detailed plan to overcome these hurdles in a prioritised and structured manner, thus achieving cost benefits. To ensure its consistency and reliability, the KB System was validated in three Oman-based maintenance organisations, and one published case study for a UK-based organisation. The results from the validation were positive with the System output suggesting list of top priorities and action plans for achieving benchmark LSS standards for these organisations. The research concludes that the developed KB System is a consistent and reliable methodology for assisting decision-makers in designing, planning, and implementing LSS for benchmark sustainable building maintenance.

O objetivo do presente trabalho é analisar a adequação e o alinhamento da metodologia de desenvolvimento de produtos de acordo com o tipo de projeto, comparando-se projetos baseados em Design for Six Sigma (DFSS) e Design Thinking (DT) em uma mesma empresa. Optou-se pela estratégia de pesquisa qualitativa, com o desenvolvimento de um estudo de caso, realizado no período de dezembro de 2015 a março de 2016, em uma empresa multinacional do setor financeiro, que utiliza ambas as metodologias. O estudo envolveu a análise de dados de oito projetos, sendo quatro DFSS e quatro DT. Para a interpretação e síntese dos resultados, utilizou-se a estatística descritiva e o teste de mediana de Mood. Os resultados indicam que o tipo de projeto e o tipo de problema afetam a escolha da metodologia, sendo possível refletir sobre a utilização de abordagens soft mais voltadas para negócios, ao invés da aplicação de abordagens hard. Projetos DT estão mais alinhados aos conceitos de projetos soft e comumente são utilizados na solução de problemas abertos. Por outro lado, projetos DFSS estão mais alinhados aos conceitos de projetos hard e geralmente são utilizados na solução de problemas fechados. Verificou-se também que o questionário de pesquisa pode ser empregado como um framework de análise para a seleção correta da metodologia a ser utilizada.The aim of this study is to analyze the appropriateness and the alignment of product development methodology according to the project type, comparing projects based on Design for Six Sigma (DFSS) and Design Thinking (DT) in the same company. A qualitative research strategy was applied, with the development of a case study, carried out from December 2015 to March 2016, in a multinational financial company, which applies both approaches. The study involved eight projects data analysis, four DFSS and four DT. To the interpretation and synthesis of the results, descriptive statistics and the Mood median test was applied. The results indicate that the project type and the problem type affect the choice of the methodology and it is possible to reflect on the use of soft approaches more focused on business instead of applying hard approaches. DT projects are more aligned with the concepts of soft projects and are commonly used in solving ill structured problems. On the other hand, DFSS projects are more aligned with the concepts of hard projects and are commonly used to solve well structured problems. It was also found that the survey questionnaire can be used as an analytical framework for the correct selection of the methodology to be applied.

Full textAbstract:
The usage of statistical methods in the production industry has resulted in quality improvements for several organisations during the last decade. However, advanced statistical methods are still underutilised and underappreciated in quality improvement programs and projects in many companies. Therefore it is of interest to investigate how these methods can be used for quality improvements in the production industry. A case study was conducted at Teufelberger’s wire rope production plant in Wels, Austria. Wire rope type BS 909 was studied by utilising the arsenal of tools and methods that Six Sigma provides, with an emphasis on statistical methods -- especially Design of Experiments. Teufelberger is currently (2016) experiencing diameter issues along the rope and it has been found through customer reclamations and quality controls in the production that the variation in a production lot can be substantial. Furthermore, there is no master setting of process parameters and each operator has their own way of setting and adjusting them, as there are different ways to achieve a product which is within given tolerances. The purpose of this study is to investigate how statistical tools can be applied to minimise variance in a Teufelberger rope manufacturing process, by conducting a case study utilising the quality improvement methodology DMAIC. Experiments were conducted in the following four sub processes which produce input components used during the manufacturing of BS909: KL-A, KL-B, IL and Al. In KL-A the following main effects were identified as significant: Postformers Spin and Postformers Diameter. In KL-B the main effect Postformers Spin was significant. In IL the following main effects were identified as significant: Compacting device, Postformers Spin and Postformers Diameter. In AL the main effect Compacting device was significant. Based on the conclusion derived from analysing these experiments theoretical master setups were created in order to address the variance issue and standardise process parameters. Further verification testing must be conducted in order to verify and tune the proposed master setups before they can be utilised.Det senaste årtiondet har användningen av statistiska metoder inom tillverkningsindustrin resulterat i kvalitetsförbättringar för flera organisationer men dessa metoder är fortfarande undervärderade och utnyttjas ej till fullo inom program och projekt för kvalitetsförbättringar. Därför är det av intresse att undersöka hur dessa metoder kan användas för kvalitetsförbättringar inom tillverkningsindustrin. Vid en av Teufelbergers produktionsanläggningar av stålvajrar i Wels, Österrike, har en fallstudie med kvalitetsförbättringsmetodiken DMAIC genomförts. Stålvajer typ BS 909 har studerats genom att använda den arsenal av verktyg och metoder som Six Sigma innefattar, med betoning på statistiska metoder och särskilt försöksplanering. Teufelberger hade för tillfället problem med främst diametern av stålvajern. Det har visat sig genom kundreklamationer och kvalitetskontroller i produktionen att variationen i en produktionsserie kan vara betydande. Dessutom finns det ej några dokumenterade optimala inställningar av processparametrar så varje maskinoperatör har sitt eget sätt att ställa in och justera processparametrarna. Detta är möjligt då det finns olika kombinationer av parameterinställningar som kan ge en produkt som är inom givna toleranser. Syftet med denna studie är att undersöka hur statistikverktyg kan användas för att minimera variansen i en tillverkningsprocess av stålvajer hos företaget Teufelberger, detta genom att utföra en fallstudie med kvalitetsförbättringsmetodiken DMAIC Experiment utfördes i följande fyra processer som producerar ingående komponenter som används vid tillverkningen av BS909: KL-A, KL-B, IL och Al. I processen för KL-A identifierades följande huvudeffekter som aktiva; Postformers-Spin och Postformers-Diameter. Den enda huvudeffekt som identifierades vara aktiv för KL-B var Postformers-Spin. För IL var följande huvudeffekter aktiva: Compacting device, Postformers-Spin och Postformers-Diameter. I processen AL var endast huvudeffekten Compacting device aktiv. Baserat på det resultat som framkom vid analysen av dessa experiment har nya teoretiskt optimala inställningar beräknats, som förväntas minska variationen i responsvariabeln diameter. De nya rekommenderade inställningarna bör tills vidare kunna fungera som ny standard för produktionen, men verifieringsförsök bör ändå utföras för att bekräfta och finjustera inställningarna.

A globalização reforça a necessidade das empresas aprimorarem seus processos e produtos continuamente para se manterem competitivas e atenderem às expectativas de um mercado dinâmico e de acionistas cada vez mais exigentes, que buscam maximizar seus lucros. A melhoria contínua acima mencionada não se refere apenas à qualidade percebida pelo consumidor final, mas também à qualidade e confiabilidade dos processos de produção. Desta forma, quando as empresas têm melhores processos, melhores são os produtos originados e também os seus custos. Porém, a questão é como esses processos são modelados na fase de projeto e como ferramentas de qualidade, sobretudo o Seis Sigma metodologia mais em voga na atualidade podem utilizar tais modelos para obter melhores resultados. Essa dissertação propõe a utilização de ferramentas de modelagem e simulação tais como as Redes de Petri para modelagem de processos produtivos fornecem um modelo formal para a representação de sistemas de produção, capturando aspectos inerentes a tais sistemas como concorrência, paralelismo e sincronização suportando a aplicação da metodologia Seis Sigma, a qual geralmente atua somente no nível de melhoria do processo produtivo e não do projeto que o originou. Dessa forma, essa dissertação trás uma proposta de integração entre os times que projetam o processo e os que executam a produção, demonstrando tal viabilidade por meio da análise dos projetos/modelos durante a aplicação da metodologia Seis Sigma. É realizado um estudo de caso na estamparia de uma indústria automotiva que ilustra a aplicação da metodologia proposta.The globalization strengthens the necessity for companies to improve its processes and products in order to remains competitive and to attend expectations of a dynamic market and shareholders each time more demanding and eager to maximize their profits. The continuous improvement mentioned above, is not related only to the quality perceived by the final consumer, but also to the quality and reliability of the production processes. Therefore, as better processe the company gets, as better would be their final products and as lower would be the costs. However, the question is wheter a continuous improvement using Six Sigma could benefit from the design documentation for the target process returning also an improved documentation after the cycle is completed. This work considers the use of Petri Nets for production processes modeling - even if any other design and modeling representation would return similar results - supporting the Six Sigma methodology application. The main result is a proposition of continuous improvement life cycle that maintains the design documentation consistent and up-to-date. Thus, this work pursuits the integration between the teams that design processes and those who implement them in the manufacturing plant. To show the potential of the models analysis during Six Sigma projects a case study is analyzed for the Press Shop area in an Automotive Industry.

Ett sätt för företag att öka lönsamhet och behålla marknadsandelar och konkurrenskraft är att ständigt förbättra sina produkter genom systematisk produktutveckling. Alfa Laval AB i Ronneby tillverkar lödda plattvärmeväxlare som förses med skyddslock och/eller skyddspluggar i flera storlekar och varianter under transport. Syftet med studien är därför att optimera skyddet med avseende på arbetsmiljö, miljö, lagerkapacitet och till en likvärdig eller lägre kostnad. Målet är att generera förbättringsförslag som ersätter de nuvarande transportskydden med ett fåtal standardskydd. Studien genomfördes som en fallstudie och följde den ingenjörsvetenskapliga Systems Engineering-metoden Design For Six Sigma (DFSS). DFSS-processen är uppdelad i fyra steg för att på ett systematiskt sätt uppnå önskat resultat och generera förbättringsförslag till fallföretaget. Studien resulterade i ett förbättringsförslag i form av en krympfilm som ersättande transportskydd. Förbättringsförslaget genererade även en reducering av antal storlekar och varianter med 80 %, vilket i sin tur reducerade lagernivåer.One way for companies to increase profitability and maintain market shares and competitiveness is to constantly improve their products through systematic product development. Alfa Laval AB in Ronneby manufactures soldered plate heat exchangers which are provided with protective covers and/or protective plugs in several sizes and variants during transport. The purpose of this study is, therefore, to optimize the protection with regard to the work environment, environment, storage capacity and at an equivalent or lower cost. The goal is to generate improvement proposals that replace the current transport protections with a few standard protections. The study was conducted as a case study and followed the Engineering Scientific Systems Engineering method Design For Six Sigma (DFSS). The DFSS process is divided into four steps in order to systematically achieve desired results and generate improvement proposals for the case company. The study resulted in an improvement proposal in the form of a shrink film as a replacement for the transport protection. The improvement proposal also generated a reduction of 80 % in the number of sizes and variants, which in turn reduced stock levels.

Det finns olika tekniska lösningar för hantering, transport och återvinning av plastindustrins spillmaterial, men vilken metod som är mest lämpad för en specifik industri är svårt att avgöra. Syftet med studien var att få ökad kunskap och förståelse för hur faktorer som arbetsmiljöpåverkan, miljöpåverkan, funktion, flödeseffektivitet och investeringskostnad påverkar val av transportlösning för spillmaterial. Baserat på dessa faktorer är studiens mål att genom en förstudie presentera ett beslutsunderlag för en eventuell investering. För att finna den mest lämpade transportlösningen och förstå det grundläggande problemet med det nuvarande systemet genomfördes en nulägesanalys på fallföretaget. Informationen låg senare till grund när en undersökning av olika lösningsalternativ på marknaden gjordes. För att urskilja de mer relevanta alternativen för fallföretaget användes en kravspecifikation samt Kanomodellen. När de relevanta lösningarna valts ut jämfördes dessa mot varandra genom en QFD-matris för identifiering av den mest lämpliga transportlösningen. Resultatet av studien indikerade genom en QFD-matris att det manuella systemet var att föredra för fallföretaget.

Na busca pela competitividade, muitas empresas acabam adotando estratégias muito semelhantes baseadas nas práticas mais usuais e difundidas em seus respectivos negócios. Além dos recursos financeiros em si, as empresas também investem tempo e esforços para atingir desempenhos semelhantes às mais competitivas, as quais julgam ser o “benchmarking”, ou seja, a referência em seus negócios. Entretanto, buscar somente se espelhar nas melhores práticas das empresas de referência não possibilita tornar-se líder no negócio, pois para tanto seriam necessários outros ingredientes, outras estratégias que façam a diferença. Quando direcionado o foco para o produto em si, no caso deste estudo em específico da indústria automobilística que é um segmento bastante competitivo no mundo, faz-se necessário estratégias muito mais sofisticadas ou muitas vezes ainda inexistentes. Mencionado por diversos líderes e executivos de grandes empresas multinacionais como uma metodologia eficaz, o Design for Six Sigma, ou simplesmente DFSS, possibilita aprofundamentos e desdobramentos muito importantes para o entendimento dos mercados, de seus clientes, das suas necessidades e anseios. Pela flexibilidade do uso da metodologia do DFSS, torna-se possível desenvolver propostas e soluções para um dos diferenciais mais importantes neste mercado competitivo, a inovação. Em função da subjetividade presente sob alguns aspectos do conceito deste diferencial, propôs-se adotar a lógica fuzzy para se trabalhar com as variáveis mais importantes de natureza linguística e, combinado à relação sinal ruído de Taguchi, mensurar de forma quantitativa o grau de inovação inerentes aos produtos. Com este modelamento, validado por meio da análise de diversos sistemas veiculares que evoluíram ao longo da história automobilística, torna-se possível comparar produtos correntes com novas ideias e propostas do ponto de vista da inovação, fornecendo assim subsídios úteis para o processo de tomada de decisão
To pursue the competitiveness, many companies end up adopting similar strategies based on the most common and disseminated practices in their respective business. Beyond the financial resources, the companies also invest time and efforts in order to achieve similar performances of the most competitive ones which they deem to be "benchmarking", i.e. the reference in your business. However, simply adopting the best practices of those reference companies will not allow become a leader in their businesses, since it would require other ingredients, other strategies that make the difference. When it focuses on the product itself, specifically in the case of this study about the automotive industry, which is a very competitive segment in the world, it is necessary much more sophisticated strategies or even non-existent yet. Mentioned by several leaders and executives of multinational companies as an efficient methodology, the Design for Six Sigma, or simply DFSS, enables to understand their markets, their customers, respective necessities and yearnings, in a deep way and their deployments as well. By the flexibility of using DFSS methodology, it becomes possible to develop proposals and solutions to one of the most important differentials in this competitive market, the innovation. Due to the subjectivity around some aspects of the concept of that differential, it is proposed to adopt the fuzzy logic, to work on the most important linguistic variables and, combined with the Taguchi’s signal to noise relation, quantitatively measure the degree of innovation inherent in the products. By this modeling, validated through the analysis of several vehicular systems that have evolved throughout the automobile history, it becomes possible to compare current products with new ideas and proposals from the point of view of innovation, thus providing useful inputs to the decision-making process

Full textAbstract:
L'elaborato espone il contributo del candidato nel processo di elaborazione di una tecnica innovativa per il miglioramento dei metodi di assemblaggio e collaudo di MU-CN. Il modello sarà di riferimento per l’analisi delle attività a valore e spreco per tutto il gruppo aziendale.
Facendo riferimento alle legioni romane: la tecnica vuole prima di tutto strutturare la strategia di attacco ovvero dichiarare come dovrebbero muoversi le legioni, poi enunciare ai singoli soldati (industrializzatori/ progettisti) come deve essere usata la spada (strumenti) ed infine quali delle spade a disposizione servono per l’attacco in questione.
Il progetto parte da uno studio di benchmarking delle best practice nel settore machinery, per poi convergere nell’approfondimento di un sistema di analisi adattato al background aziendale. Si utilizzeranno strumenti quali il Design for Assembly e l’Approccio Scientifico. Questi saranno i 2 approcci fondamentali con cui si procederà alla generazione di un nuovo metodo per le attività esecutive. Inoltre, in termini di completezza di analisi si investirà anche il processo di sviluppo nuovo prodotto, cercando di anticipare il più possibile (front-loading&concurrent engineering) la rilevazione delle inefficienze. Infine, vi sarà il supporto del candidato nell’istituzionalizzazione del nuovo metodo, nella conduzione di attività d’implementazione pilota e nell’elaborazione dei piani di roll-out che lo vedranno in veste di trainer insieme al Team di Progetto.
I risultati ottenuti sono stati soddisfacenti, perciò la tecnica proposta avrà riscontro reale e verrà implementata nel Gruppo entro fine 2018. In particolare, si sono incrementati i rendimenti medi delle linee osservate e ridotti i costi di assemblaggio e struttura dei pezzi analizzati, dati stimati grossolanamente grazie all’applicazione pilota della nuova tecnica.

Abstract：Why design a not perfect process or product and try to improve it with the DMAIC of Six Sigma? DFSS (Design for Six Sigma) is customer-oriented and hits straight to the point at the design stage of products or processes. It gets things done once and for all, replacing subsequent “improvement” with “prevention” in advance. The variation is narrowed to an acceptable range to customers and the production process is under control to reach the quality standard of the Six Sigma.DFSS is not to replace the current product development flow in a enterprise organization but to systematically integrate the related tools, methodologies, and team members during the design process. Goods or services developed with DFSS will be able to meet customers’ expectations and save time for enterprise organizations, improving quality and accomplishing financial effectiveness.. This research is aimed at exploring “DFSS”, which can get straight to the point and solve problems at the development stage of a certain product or process and consider feedback from the voice of customers or the technology to pursue products of higher quality and make profits. Items to be explored include: (1) Understanding the core process of DFSS and the application of main tools and effectively applying them to the R&D design process, truly realizing the minimum variation and prevention purpose of DFSS, accomplishing the maximum effectiveness of investment (manpower, finance), and enhancing the problem-solving capability. (2) Comparing the effectiveness before and after applying DFSS. (3) Constructing the R&D process model for new products through case study on practical examples.The main contribution of this research is constructing a systematic exemplary application model that is applicable to the new product R&D process in domestic enterprises.

Ao longo dos últimos anos, tem-se verificado que Portugal não tem conseguido reduzir o
número de incêndios florestais, que ocorrem essencialmente nos meses mais quentes do ano.
O ano de 2013 foi particularmente grave, devido não só à elevada extensão de área ardida,
mas sobretudo pela incidência de acidentes pessoais, dos quais resultaram a perda de vidas
humanas. Esses bombeiros que perderam a vida no combate aos incêndios morreram devido
a queimaduras graves e não por causa de outro tipo de acidentes. A utilização de um
vestuário e equipamento de proteção individual, assim como um comportamento e atitude
corretos, por vezes não são o suficiente para evitar que os bombeiros corram perigo.
Desta forma, esta tese de mestrado vai de encontro às limitações existentes neste campo,
tendo como objetivo melhorar as caraterísticas de um dos equipamentos de proteção
individual que os bombeiros utilizam no combate aos incêndios florestais, mais
propriamente das cógulas de proteção. Para isso, é aplicada a metodologia Design for Six
Sigma (DFSS), mais propriamente o mapa DMADV (Define, Measure, Analyse, Design,

necessidades e expectativas do cliente.
No final desenvolveu-se um cógula com novas caraterísticas, que vão de encontro a algumas
das necessidades do cliente, nomeadamente, incorporação de uma máscara de retenção de
partículas e de um equipamento constituído por sensores de medição de temperatura e

Full textAbstract:
Six Sigma or high level of process output is very common interest of world class industry. Six Sigma methodology not only ensures the quality of products but also ensures the quality of each element associated with that product, from conception to the end of the product life cycle. Because of such ensuring, Six Sigma qualities made an evolution in industry in 1990's. Now Six Sigma is almost a proven methodology for industry to produce high level quality of products. To achieve Six Sigma quality, industries need to optimize the process; there are many mathematical, engineering and statistical methods that are being used for optimizing the process. However, these methods do not always deal with a combined consideration of the effects of mean and variability of quality characteristics of the product. One of the major steps to achieve a high level of quality is to optimize the process. It is well known that processes have many inputs, and inputs are key element to the quality of process output. Therefore, optimization of the process contributes a vital impact for Six Sigma. The proposed Taguchi robust method optimization will take both effects such as mean and variation of product quality characteristics into consideration. In view of Dr. Taguchi's very popular phrase "loss to society", in this research we applied Taguchi method to optimize the process for Six Sigma design. We showed that a positive gradient relationship exists between S/N ratio and process sigma. The robust design method ensures minimum variation of quality characteristics of the product or to produce almost "defects free" products. Due to such minimal variation in product, it will ensure minimum use of resources for manufacturing of product. Therefore unit cost of production will become lower and as well as it satisfies customer's implied and stated need. These are the main objectives of Six Sigma design and this research contributes to formulate a generalized and easier method to optimize the process for Six Sigma design in an industry.

The quality of commercial space design continues to command an inseparable foothold in consumer equity, consumer psychology and business profitability. With the important role that the quality of commercial space design commands, it is becoming increasingly importance in terms of how the designer is able to come up with effective and consistent means of design conception. In the domain of space design, where the topic of “How best to conceive commercial space design that offers quality” remains underrated, the study has chosen to examine the definition of quality through quality management publications and to examine means of conception that benefits commercial space design that helps to achieve the definition of quality through the quality design methodology – “Design For Six Sigma, DFSS” much sought after by the quality control sector presently. The study’s main objectives pertain to examining how the DFSS is able to help bring quality to commercial space design, and then to proposing conceptual references that help to bring commercial space design in line with prescribed quality demands. The scope of this study mainly encompasses on examining the psychological aspects of quality. The content of the study execution comprises of, 1) To explore the definition of quality through reviewing archival publications for building a research foundation; 2) To analyze how the DFSS can benefit commercial space design by examining DFSS related publications and explorative interviews with field commercial space design operators; 3) To explore the means for zeroing in on quality objectives in commercial design by examining commercial space design related publications and factual commercial space design experience data; 4. To propose reference conceptualization methodology that helps to attain the definition of quality in commercial design. The study aims to focus on the definition of “Quality being with minimal resource depletion for maximum emotional moving results” as the premises, where the definition is made to reflect a maximum adaptation of design resources on the one hand, and to reflect the accuracy of the design objectives locked in on the other. The study has unveiled that, 1) The “Conceptual assessment and conceptual analysis” under the DFSS’s identification, optimization, validation and development phases are found to be beneficial in closing in the quality demand of “minimizing resource depletion” in commercial space design; 2) The conceptual framework of being “Emotionally moving” that help to achieve the quality definition in commercial space has derived from examining the spatial characteristics unique to a commercial space, in which the quality-related spatial characteristics consist of attraction, emotional association, wonderment, reminiscence, and energy transference; 3) The conceptual reference in the overall definition of attaining quality in commercial space lies in mapping out a “Commercial space’s DFSS”. And the study’s explorative findings are intended to provide references to relevant industry operators.

Looking back at the history of quality management, it’s found that most quality control activities focus on product quality management in manufacturing, yet less apply to Engineering, Procurement and Construction (EPC) industry. The case company is operated between manufacturing industry and service industry. It implements the ISO 9001 quality management system and the standard is already deeply rooted in the company. In the process of internationalization, the case company pursues excellence in quality and intends to become a leading Global Provider of Engineering Service and Innovative Technologies. Thus, this research is aim for introducing Six Sigma to assist it achieving the goal. The case company has implemented a complete ISO 9001 system as well as an in-house assistant quality control system. Meanwhile, the management team repeatedly emphasizes the importance of quality; however, some quality defects has resulted in massive loss and schedule delay, leading to the company’s executive officers spending plenty of time on problems solving. Why is the case company having quality problems? Are there inherent limits of the existing quality management system? To solve out the problems, this research is to explore whether introducing Six Sigma would enhance quality level, and prove that the Six Sigma is the scientific method to bring the case company to the destination of perfect quality. At the same time, it provides practical experience and suggestion as a reference for similar industry. The research has gone through 10 months and followed the Six Sigma method. In the end, it has been proven that if the company expects to enhance its competitiveness by continuous quality improvement, it is necessary to implement Six Sigma no matter the company has already adopted ISO 9001 system or not. There is no conflict between these two management methods. Parallel implementation of the two management methods and integrating them into one complete quality management system is workable. It can effectively enhance management value and quality level, and th

Besides the vigorous development of Internet and the technology change with each passing day, facing the rigorous milling of rapid change of global economical situation, technical innovation has become the key advantage of a corporation. In order to implement the technical innovation, the most practical and prospecting way is to plunge into the “Research and Development” (R&D) task. Only by rigid project planning with procedure control and teamwork can shorten the design cycle time and actually exploit the efficiency of innovative R&D. 6 Sigma is a kind of total quality management philosophy that emphasizes “Strategy management” and “Humanity awareness”. Combining with statistical quality control method, it achieves the quality goal of failure rate lower than 3.4ppm. That is, the ideal “zero defect” goal has come true by the effective control of scientific method. Based on this, this research is to study the project on shortening the design cycle time by use of 6 Sigma DMAIC approach in information electronic industries. What are the variables that should be considered in practical application when trying to establish a standardized flow control mechanism? What kind of communication channel should be set up? How and when should the control point be installed? Considering the competitive circumstance, what kind of policy and method should be used to achieve the improvement on the organization and to increase the competitiveness? This research can be a useful reference to corporations that need to carry out R&D projects.

In today’s booming service economy, providing customers with high-quality and quick services has been widely recognized by many world-class organizations as an essential means of achieving business excellence. Moreover, the capability of delivering excellent service quality in a fast time-to-market manner is directly tied to a superior service process for the service delivery. Therefore, this doctoral research aims at developing strategies for obtaining the service processes which are capable of fast delivering higher level of service quality based on two different perspectives. One perspective is about how to improve the existing service processes, and the other one is to deal with the issues of new service process design and/or redesign. Firstly, for the purpose of service process improvement, two state-of-the-art quality approaches, Lean Production (Lean) and Six Sigma were investigated and applied together to developing a Lean Six Sigma methodology. The rationale for the combination of these two popular initiatives in the modern quality management field is based on the complementary benefits obtained from implementing Lean and Six Sigma methodologies individually. On the other hand, to serve the need for designing and/or redesigning new service processes, an integrated methodology was developed by combining Lean with Design for Six Sigma. Similarly to the Lean Six Sigma strategy, an argument for the combined approach was also demonstrated. Finally, three empirical case studies were conducted to examine the efficacy of these integrated methodologies for their applications to service in particular. Among them, two cases were for the implementation of the Lean Six Sigma methodology, and the other one was then for the application of the Design for Lean Six Sigma methodology. The achievement obtained from implementing these project cases have highlighted the good capabilities of the methodologies proposed in this research, and therefore it is believed that they can be applied to the service field for performing the tasks of process improvement and/or new process design. Keywords: service; Lean; Six Sigma; Design for Six Sigma.

Nowadays, the technology of the heat seal connector is one of popular manufactures in common use for liquid crystal display module, LCM. The technology is the connecting LCD and PCB terminal by heat seal paper connecting without silicone rubber connector, which was a traditional type of the manufacture with chief defects on increasing the weight and thick of the product. To compare with other technologies of manufactures, the advantages of the heat seal connector is on reducing the production cost. Without silicone rubber connector, the product would be made thinner, lighter, shorter, and smaller with high quality of dots per inch. Therefore, heat seal connector can be one of the main streams of the manufacture. Using the six-sigma procedure and Taguchi Methods, the optimal process parameter combination is determined in this research. After analyzing the possible factors of the manufacture of the Heat Seal Connector by Cause-and-Effect Diagram, the key factors and their optimal combination are determined by using Prioritization Matrix and Taguchi parameter design. The key factors are thick of copper, heat seal temperature, heat seal process time, heat seal pressure. Result shows that heat seal connecting strength increases from 490.6kg/cm2 to 698.3kg/cm2; Cpk increases from 0.99 to 6.81. It does not only accomplish the objective desired, but also the result is better than the estimation.

Design for Six Sigma (DFSS) has been utilized over the last few decades to deliver more robust products with more functionality and reduced cost. Enterprises that want to compete in the market must operate deploying flexibility, minimizing production costs, speeding up processes and assuring a high-quality level of output. For these reasons it is necessary to apply innovative and structured methodologies able to suggest techniques and methods to design, organise and manage industrial processes. DFSS represents one of the most effective methods to attain increases in business performance and customer satisfaction using a smart problem-solving method (DMADV). This study shows an implementation of a DFSS project in smart phone manufacturer to improve the performance level of the design process. The results of the case study demonstrate an effective approach that is able to design and reach Six Sigma level process, by applying KJ model, quality function deployment (QFD), TRIZ innovation, Monte Carlo simulation, reliability prediction of electronic equipment and design of experiments (DOE) tools. This case justifies the application of DMADV method in order to improve the performance level of design process.Finally, we use an index year return rate (YRR) from TL-9000 to evaluate the measurable effect of telecommunication industry product design quality. This DFSS process was practiced in A company actually. We found the YRR of R project (with DFSS process) is 1.23% that better than K project (without DFSS process) YRR 5.05%. The results of this case study show that with DFSS process could shorten new products development period, selected suitable components, estimated product life cycles and make enterprises with competitiveness advantage.

Nowadays, in order to meet the requirement from different customers and to confirm functions of their product, network corporation usually do many test before shipping. To gain more profit, they setup more and more test stations to increase production capacity but lead to unstable test result and low yield rate. We further do some analysis to the defective products and find out the problem that is caused not by quality of the products but signal interference in test stations. More than ninety percent of retest products is good product. This may lead to lots of product retest procedure, low production capacity and time cost. In the thesis, we propose a method to lower the retest rate of Wi-Fi product by using six sigma DMADV structure. Firstly, we use QFD (Quality Function Deployment) table to convert voice of customer to design the product specification. Secondly, we use GRR (Gauge Repeatability and Reproducibility) to analyze measurement variation of each test station and to check the key factor of test station. Thirdly, we use TRIZ (Theory of Inventive Problem Solving) theory to activate the concept for designing test station. Fourthly, we use Taguchi Methods to refine the robustness of our method. In this way, we can control the WiFi signal path consistency and reduce multi-path interference. Finally, to verify the method, we do a pilot run. After analyze the report, this method can lower about 10% retest rate and to save test cost by at least 10 million dollars per year.

This dissertation reports on the research work of a new business improvement methodology called the design for Six Sigma (DFSS) conducted within a global resources company with specific reference to Manganese Metal Company (MMC), a subsidiary of BHP Billiton (BHPB). The aim of this research was by means of a case study, through action research, to investigate, analyse and evaluate the "Define, Measure, Analyse, Design and Verify" (DMADV) model proposed by Picard (2004) with specific reference to a new product design. The study was concerned with identifying the BHPB strategic business reasons, effects and analysing the financial impact of implementing a DFSS project pertaining to a new product design at MMC. The literature review highlighted that DFSS enhances revenue growth, quality and reliability for a new product. The key findings were that DFSS does not exist within MMC and BHPB, the DFSS methodology could improve and enhance the revenue for a new product design at MMC and none of the BHPB customer sector groups are reporting any operating excellence (OE) annualised cost improvement benefits for DFSS projects. The main recommendation emerging from this research is that an integrated DFSS process will enable BHPB to identify critical leverage points for improving the overall financial performance in achieving the FY09 OE objective of $1 billion in annualised cost improvement benefits thus achieving the world class benchmark standard set by General Electric Corporation.

Lean production policies have been identified as suitable to ensure maximum capacity utilization and the cost of the smallest process. Essentially it was not easy to re-standardization of lean production and re-added value potential. This study was to use the New Product Development (NPD), Lean Thinking, TRIZ theory and management of Six Sigma-DMAIC process steps of the four theoretical concepts, to generate a combined effectiveness, and applied in R&D stage of process improvement with NPD, Lean Thinking, TRIZ and Six Sigma-DMAIC process systems coexist in the same concept applied to new product development stage process, to ensure that the improvement of internal processes and meet Voice Of Customer (VOC). This study used Lean Thinking, Lean-Toolkits, TRIZ and Six Sigma-DMAIC approach applied to NPD in R&D testing and verification phase. A gradual improvement in the lack of existing internal processes, prompted by the correct wrok processes have a better output and time-saving benefits, but the waste process can be found through the Value Stream Mapping (VSM), and for the waste points to do a study and improvement through continuous improvement of processes, in order to let overall process can achieve the perfect proportions. In this study, using Lean Thinking, TRIZ and Six Sigma-DMAIC approach the three theoretical concepts focus on the case of new product development in R&D testing and verification processes phase. In order to improve product development process to reduce waste process time, company had to integrate new product development process and testing and verification process to save time. The study results of the company improved by 16.1 hours of working hours, it means not only the company could save two working days for development testing and verification costs, but also takes VOC. R&D faster means more competitive than other competitors. By applying Six Sigma-DMAIC and Lean Thinking techniques to identify problems, combined with TRIZ theory to find the best solutions, such practices can improve product quality system standards, reduce company costs, improve customer satisfaction, and more to enhance the company in the industry competitiveness.

It is critical for company to come up with new product quick in this everchanging market. The small and medium enterprises in Taiwan usually focus on manufacturing and don’t invest much in resreach and development of new products. It is necessary to implement a systemeatic approach to help companies to quickly generate innovative products within limited resources. In this research, Deisgn for Six Sigma (DFSS) and TRIZ methodology is adopted to help an ergonomic office chair manufacturer to rapidly find the direction of next generation product. In this study, all steps of DFSS, i.e., DMADV (Define, Measure, Analyze, Design, Verify), are used to help the company to generate new generation product. In the definition (Define) phase, questionnaires are used to collect customer voices and expectations of ergonomic chairs. The result shows that after a long period of sitting, the cushion temperature increases, which causes diccomfort. In the measure (Measure) stage, through Kano and QFD tools, the customer voices are transferred into product design parameters. The airtight material of cushion is the major reason that cause discomfort of users. In the analysis (Analyze) stage, TRIZ methodology is used to reinforce the inadequacy of DFSS. By using TRIZ methods, this research is able to solve the contraditions and find a fine solution in knowledge database, the Ranque Effect, to break the airtight and supportive material contradition. Finally, in the design (Design) stage, through the experimental design, this study is able to identify key factors, allowing to optimize the design of ergonomic office chair. Then a pilot run is established in the verification (Verify) stage to validate the feasibility of proposed idea.

After being proposed by Motorola in 1980s, Six Sigma has aroused the intense attention and discussions from all walks of life. So far, all trades still use Six Sigma often to be the management methods to improve the quality, and increase an enterprise’s profits reaping. There are cases of introducing Six Sigma whether in the manufacturing industry, the service industry, even the construction industry; the project management technique of Design for Six Sigma (DFSS) offers a tool of new product development process improvement and reengineering. The research adopted the machine tools industry in Taiwan as the subject, started from defining the new product development process, designed the new product development process reengineering project after doing the performance evaluation and factor analysis by means of the results of the questionnaire, and advanced the method of doing the tests and verification by the product data management system to construct a performance evaluation mode that conforms to the Six Sigma Design procedures. The research expects to integrate the existing new product development processes through the DFSS management framework, and there are three objectives: (1) To develop the key success factor of new product development process performance; (2) To establish the new product development process performance evaluation mode; (3) To draft the process reengineering project, and provide the new product development process performance evaluation mode to be the basis of reference for the industrial circles to introduce Design for Six Sigma.
