Abstract:

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, February 2006. Includes bibliographical references (p. 74-76). Lean was first adopted as a management technique for improving results in manufacturing environments. It is based on the 5 principles of identifying the Value to be created, mapping the Value-Stream (incremental addition of value), ensuring process Flow, orienting the process towards the Pull of the customer and finally eliminating all Waste through a process of continuous improvement. This framework is highly adaptable, and has been applied in recent years to non-manufacturing efforts, such as product development and the retail and service industries. We explore the application of Lean to voting. Applications can be found in the phases of technology development, production, deployment, poll management and more. By following a structured approach based on Lean, the efforts to advance voting solutions in the US can gain in efficiency, security, privacy and credibility over their current state. These will be adapted to deal with the voting environment, which imposes a unique set of challenges and follows priorities different from normal corporations. Additional Lean elements, such as eliminating irregularities through standardization, improved training and process transparency will be reviewed. (cont.) The development and deployment of Brazilian voting system will be presented as an example of how Lean elements can be used in the voting setting. While not intentionally created by the Lean model, the design, deployment and current use of the Brazilian system is highly complimentary to this model. Finally, we suggest ways in which such an approach can be applied to the U.S. voting system. With a theoretical structure in place, specific improvement efforts can be devised and applied in the field. This study, therefore, is intended as a preliminary effort of identifying a problem and modeling it. It hopes to induce a commitment to Lean which will put in motion a cycle of implementation, elaboration and continuous improvement. by Tomer Posner. S.M.

Thesis (MBA)--University of Stellenbosch, 2009. ENGLISH ABSTRACT: The political changes in South Africa since 1994 and globalisation have brought about a dramatic increase in competition for South African companies. To ensure long-term survival and success, companies have to focus their strategies on continuous improvement and the ability to adapt to continuous change. Lean manufacturing principles were derived from the Toyota Production System (TPS) which was created by Taiichi Ohna, who is widely credited to be the father of Lean manufacturing principles. Lean principles originated in the automotive industry and transformed an industry that previously focused all its improvement efforts on the theory of mass production. Lean principles can be summarised as continuous improvement through focus on the elimination of waste from processes. Lean principles specify that organisations: • Change from using their view to using the view of the customer when evaluating value-creating activities; • Change production plans that focus on mass production to production plans that produce only what customers want now in flow production with small production batches; • Reduce lead times; • Improve quality; and • Achieve the above-mentioned by eliminating waste in all processes. Lean principles are based on the assumption that once waste is removed, the process improves and results in reduced lead time, improved quality, reduced costs and improved customer service. The aim of this research study was to test Lean principles by implementing applicable parts of it in the engine rebuilding section of MultiMech, a division of Golden Arrow Bus Services. The changes that formed part of the implementation included: • Reduced work in progress through improved production planning; • Improved performance of inbound processes through improved communication based on improved production planning; and • Improved productivity due to improved inbound processes and improved performance measuring. The results from the pilot implementation of Lean principles at the engine rebuilding section support the benefits documented in the theory. The major results were: • An increase in the number of engines built for the months June to September, from 54 in 2007 to 88 in 2008 which represents a 63 per cent improvement in productivity; • A decrease in the number of works orders from 58 to 21, which represents a decrease of 63 per cent in work in progress; and • A reduction in stores' lead time from 3.5 days to 1.4 days, which represents an improvement of 60 per cent. The results from the pilot implementation is only an indication of the total potential that will be realised when Lean principles are implanted throughout MultiMech. AFRIKAANSE OPSOMMING: Die politieke veranderinge in Suid-Afrika sedert 1994 en globalisering het 'n dramatiese verhoging in mededinging vir Suid-Afrikaanse maatskappye tot gevolg gehad. Ten einde langtermyn oorlewing en sukses te verseker, moet maatskappye hul strategiee fokus op aanhoudende verbetering en die vermoe om by konstante verandering aan te pas. 'Spilvrye' vervaardigingsbeginsels ('Lean manufacturing principles') is afgelei van die Toyota produksiestelsel ('Toyota production system') (TPS), wat ontwikkel is deur Taiichi Ohno, wat algemeen beskou word as die vader van spilvrye vervaardigingsbeginsels. Hierdie beginsels het ontstaan in die motorvervaardigingsindustrie en 'n industrie transformeer wat voorheen al sy verbeteringspogings gefokus het op die teorie van massaproduksie. Spilvrye beginsels kan opgesom word as konstante verbetering deur te fokus op die eliminasie van verspilling uit prosesse. Spilvrye beginsels bepaal dat organisasies: • Nie meer vanuit hulle eie perspektief nie, maar vanuit die klient se perspektief waardeskeppende aktiwiteite beoordeel; • Produksieplanne verander wat fokus op massaproduksie tot produksieplanne wat slegs produseer wat kliente nou wil he in 'n vloeiproduksieproses met klein produksievolumes; • Wagperiodes verminder; • Kwaliteit verbeter; en • Bogenoemde bereik deur verspilling in alle prosesse te elimineer. Spilvrye beginsels is gebaseer op die aanname dat sodra verspilling verwyder is, die proses verbeter en verkorte wagperiodes volg, kwaliteit verbeter, kostes verminder en klientediens verbeter. Die doel van hierdie navorsingstudie was om Spilvrye beginsels te toets deur toepaslike gedeeltes daarvan te implementeer in die enjinbou afdeling van MultiMech, 'n divisie van Golden Arrow busdienste. Die veranderinge wat deel uitgemaak het van die implementering sluit in: • Verminderde werk-in-proses deur verbeterde produksiebeplanning; • Verbeterde prestasie van inkomende prosesse deur verbeterde kommunikasie gebaseer op verbeterde produksiebeplanning; en • Verbeterde produktiwiteit as gevolg van verbeterde inkomende prosesse en verbeterde prestasiemeting. Die resultate van die loodsimplemetering van Spilvrye beginsels by die enjinbou afdeling ondersteun die voordele wat in die teorie gedokumenteer is. Die vernaamste resultate sluit in: • 'n Toename in die aantal enjins gebou vir die maande Junie tot September, van 54 in 2007 tot 88 in 2008 wat 'n 63 persent verbetering in produktiwiteit verteenwoordig; • 'n Afname in die aantal werksopdragte vanaf 58 tot 21, wat 'n afname van 63 persent in werk-in-proses verteenwoordig; en • 'n Afname in store se wagperiode van 3.5 dae tot 1.4 dae, wat 'n verbetering van 60 persent verteenwoordig. Die resultate van die loodsimplementering van Spilvrye beginsels is 'n teken van die totale potensiaal wat gerealiseer sal word met die implementering in ander departemente van MultiMech.

Thesis: M.B.A., Massachusetts Institute of Technology, Sloan School of Management, in conjunction with the Leaders for Global Operations Program at MIT, 2018. Cataloged from PDF version of thesis. Includes bibliographical references (page 71). A universal imperative of most manufacturing firms is to lower cost, increase production rate, and deliver exceptional quality for every product. The manufacturing firm that springs to mind as the standard bearer for all three is Toyota and the generalized lean manufacturing method known as the Toyota Production System. The literature on what lean manufacturing is and how to do it is vast. This thesis first contributes to that cache of lean literature an example of one aerospace company's interpretation of lean and how it is defined in assembly production design. In other words, this thesis tests the claim that lean principles can be incorporated in the design of an aircraft assembly process to achieve the lean goals of producing a perfect product with zero waste at the rate at which a customer demands it. The thesis covers a seven-month research period at an aircraft assembly factory and is broken into three phases. The first phase presents research on an existing lean transformation initiative in the factory and measures its success at achieving lean goals. This evaluation determines that the as-designed system does meet the goals of lean to continuously improve and eliminate waste but also exposes problems to other sub-systems in the factory. Phase I identified several improvement candidates for deeper study, and the rest of the thesis considers one of these opportunities, specifically on the material delivery system. The second part of the thesis focuses on a root cause analysis of the problems associated with the material delivery system at meeting lean goals. The resulting question is what changes to the material delivery system are required to further these goals. The company was already considering several solutions to answer this question; however, the proposed solutions would violate the original design requirements for the system. This hindered the ability to make improvements. The third part of this thesis examines the redefinition of the design requirements that embody lean principles as well as other requirements imposed on the system. This allows for new solutions to be evaluated against the design requirements and a final recommendation is proposed. by Dora Leanne Aldama. S.M. M.B.A.

Includes bibliographical references (p. 179). Expanding Lean principles beyond the manufacturing floor, ultimately to entail a comprehensive Lean Enterprise, has gained increasing attention among corporations. This thesis entails a detailed case study of initiating a Lean Transformation in the Supply Chain department of a technology center for engineering, integration and final assembly of directional drilling equipment. This technology center is part of Schlumberger, a global corporation and industry leader in directional drilling and other oilfield technologies and services. Initiating the Lean Transformation in this Supply Chain department is detailed and used as the central theme throughout the thesis. The rapid, successive applications and results of conventional Lean principles are evaluated. Due to the near relative proximity of the several initiatives undertaken, in both time and within the organization, this case is used to evaluate the Autocatalytic Nature of Lean Principles within the Supply Chain department. Concurrently, the dynamics involved with the interactions of personnel within the department are evaluated. As a Lean Transformation is so heavily dependent upon the personnel participating in the change, tactics for initiating a Lean Transformation are treated in reference to the several initiatives of this case study. These three components, Lean principles, their autocatalytic interaction, and relevant human interactions, are all combined to comprehensively address the most influential aspects of affecting a Lean Transformation in a Supply Chain department. by Bryan Gardner.

Includes bibliographical references (leaves 74-75). This thesis describes the work performed over a six and a half month internship at Eastman Kodak Company in Rochester, NY. The thesis focuses on the implementation of a lean manufacturing system, modeled after the Toyota Production System, in the Kodak color film business. The goal of the system is to systematically eliminate all forms of waste from the production process in an attempt to reduce costs and inventory. This thesis approaches the problem from two different points of view. On the one hand, it takes a high level view of the entire supply chain and describes how material and information should flow through the supply chain. It highlights where inventory buffers should be located and which operations should be improved in order to reduce the size of these buffers. Finally, this thesis highlights the importance of leveling the customer demand signal in order to implement a true pull system using Kanbans. On the other hand, this thesis describes the implementation of lean manufacturing tools such as Kanban systems and Heijunka boards in some Kodak operations. This work includes the use of tools such as visual signals, cellular manufacturing, Kanbans, Heijunka boards, etc. The work performed over the internship sets the foundation for the transformation of the Kodak supply chain into a lean supply chain capable of dealing with uncertain demand. Additionally, the work can easily be transferred and applied to other Kodak businesses such as paper and photochemicals. by Emanuele F. Gillio. S.M.

This thesis is focused around the development of the principles of lean that are most relevant to Intel's complex manufacturing flow and then the application of these principles to improve the operations in a focused area, the Sorting floor. Direct examination of the work in Sort raises the awareness of inefficiencies from overproduction and inventory; viewing this work as a series of structured activities, customer-supplier connections, and simplified flows further crystallizes the need for a structured approach towards WIP management. A pilot implementation of a CONWIP control of inventory demonstrates reductions in cycle time variability and provides a foundation for further improvements. In conclusion, the challenges experienced with changing the manufacturing systems in Sort were largely organizational and likely to be seen in many other operational areas at Fab 23. by Roy C.

Includes bibliographical references (p. 73-74). Many companies have realized significant value through the application of lean principles to manufacturing and supply chain operations. Dell Inc. in particular garnered international fame for its ability to manufacture and deliver computers using a lean, direct-to-customer approach that provided a tremendous competitive advantage. The Author suggests that these same lean principles can be applied to improve a firm's service and support operations, while acknowledging some important nuances of applying lean in a customer service environment. The Author calls to light a key differentiator between lean manufacturing and lean customer service. Specifically, while customers use relatively consistent value systems to assess manufacturing operations, different customer segments typically value customer service in very different ways. Thus, lean customer service must begin by thoroughly characterizing the value expectations and contributions of each customer segment. After characterizing these value systems, a firm must design a support channel architecture aligned with the value exchange system of the entire customer population. After designing a lean channel architecture, lean principles may be tactically applied to optimize performance within individual channels. This research project focused on improving customer service operations at Dell by using lean principles to: 1. Establish a data-driven, strategic architecture for Dell's consumer support division and 2. Identify operational improvement opportunities to drive the tactical execution of that strategy. The project began with a benchmarking study of customer service strategies at companies such as Best Buy, Apple, Fed-Ex, Amazon.com, GM, and Comcast. (cont.) The Author then proposes a "Lean Support Channel Architecture" using on-line and retail service channels to offload demand from the call centers, effectively eliminating waste from call centers. Finally, the Author examines how lean principles can be tactically applied to a retail service channel to enable the cost-effective delivery of retail support in line with the support channel architecture proposed. by Hannah Elizabeth McClellan.

Abstract:

Thesis (S.M.)--Massachusetts Institute of Technology, System Design and Management Program, February 1999. Includes bibliographical references (p. 85). The aerospace market is as demanding as many industries in terms of the challenges on firms to deliver world class performance and quality at reduced cost and lead-times. These challenges extend to the military side of the aerospace market which is faced with the challenge of developing, delivering and supporting systems with ever increasing complexity in an environment of significantly reduced defense budgets. These challenges suggest that application of innovative improvement strategies will be required for market success. Additionally, the ability of the armed forces to maintain superiority in this environment is highly dependent on the aerospace firms' achievement of significant reductions in the cost of ownership of these systems. Since the major portion of the cost of ownership of aerospace systems is determined by the decisions made during the product development process, focus of improvement efforts on this portion of the product life cycle is key to achieving success. Recent research by James P. Womack and Daniel T. Jones suggests that application of five lean principles to the processes across the entire enterprise will lead to achieving a "lean" stale. This lean state results from the elimination of waste from operations such that products can be developed with a minimum of overall expense in terms of human effort, material and time. Nevertheless, the bulk of the discussion and application examples in this and other recent research have largely been focused on the manufacturing portion of the value stream. There are many examples in industry of where these principles have successfully transformed manufacturing organizations. But product development organizations have been struggling with how these principles apply to product development and what "lean" really means in the product development context. This difficulty in translating lean principles to product development is partially due to the differences between the processes used in the manufacturing setting and the product development setting, and the differences in the 'product' which these processes produce. The problem to be studied in this thesis is whether value stream mapping and lean principles, which have been successful in facilitating the lean transition in manufacturing, are effective tools in identifying waste and identifying an improved product development process future state. This thesis will study the application of value stream mapping to a military aerospace product development program at Pratt & Whitney. Although it is recognized that in order to achieve the goals of lean thinking one has to apply the principles enterprise wide, this work will be limited to looking at application in a specific portion of the product development process. In so doing, sufficient process breath will be covered for demonstration purposes, while the scope of work will be limited consistent with the intent of this thesis. Prior to the case study, each of the lean principles is investigated from a product development perspective hey researching the underlying concepts and comparing them to recent business process work of others. The primary focus will be on the definition of Value in product development and the Value Stream mapping process. Additionally, a survey of product development engineers is conducted which supports the existence of similar types of waste in product development as is seen in manufacturing. by Robert A. Slack.

Abstract:

Thesis (S.M.)--Massachusetts Institute of Technology, System Design & Management Program, 2000. Includes bibliographical references (p. 100-101). This thesis shows that lean principles that have been successfully applied in manufacturing can also be successfully applied across an entire enterprise. Established lean principles and lessons learned in lean manufacturing environments are applied across an automotive fuel system enterprise. This enterprise includes all major activities used in developing and delivering fuel systems to customers from the initiation of the systems concept to final production manufacturing. The value of the enterprise's product (fuel systems) is specified in terms of enterprise customers. The value stream of the fuel system enterprise is identified and analyzed using process mapping, input/output information flow diagrams, and other techniques. Major issues in terms of waiting time, rework time, and excessive need for validation are identified using these techniques. Countermeasures against these issues are offered to facilitate a transition to a leaner state. The goal is to develop a systemic understanding of the fuel system enterprise such that lean principles and tools can be applied to its processes to improve efficiency, throughput, and value for customers. Recommendations for further study are also listed in an effort to pursue perfection by continuously improving the lean enterprise. Finally, a transition to lean implementation plan is outlined. by Marc Anthony Schmidt. S.M.

Abstract:

Thesis (S.M.)--Massachusetts Institute of Technology, System Design and Management Program, 2007. Includes bibliographical references (p. 108-111). Delays and cost overruns are the rule rather than the exception in the construction industry. Design changes due to lack of constructability late in the construction phase generating costly ripple effect which create delay and disruption throughout the entire organization, are the largest contributors to the stated rule. In the building construction industry, of increased competitiveness, demand from many companies continued effort to develop new methods and tools, in which the design for quality, cost, construability and reliability play an important role. The planning and management of building design has historically focused upon traditional methods of planning such as Critical Path Method (CPM). Little effort is made to understand the complexities of the design process; instead design managers focus on allocating work packages where the planned output is a set of deliverables. This current design method forces design teams to manage their work on a discipline basis, each working on achieving their deliverable as dictated by the design program with little regard of the relationship with other disciplines and organizations. In addition, because Architect and Engineering firms view design and construction as two separate independent phases of work in project it makes it difficult to verify constructability in a design and create flow in the overall process. The goal of this study is to look at how aligning interests, objectives and practices based on lean fundamentals, during the earliest stages of a project, as a method of improving construction performance. by Leticia Soto.

Abstract:

Thesis (S.M.)--Massachusetts Institute of Technology, System Design & Management Program, 2005. Includes bibliographical references (p. 109-111). Lean principles have been applied throughout the manufacturing industry with noted success although the process of integrating them into the entire enterprise has been complex and slow. Certain areas of the automotive industry, specifically product development, require a deeper study of its readiness to transition to lean. This thesis analyzes the product development enterprise at a large North American based auto manufacturer with respect to cultural and procedural inhibitors to becoming lean. The traditional lean principles and historical advancements in lean techniques are presented along with a description of the area studied. The scope of analysis focuses on three major phases in product development; the early concept phase, the middle core design phase and the launch phase. Recently, there has been difficulty in translating the lean principles into the product development environment. In this study, unique product development definitions of the lean principles are required and used to develop a framework for analysis. Inhibitors or barriers were discovered through interviews, observations, documentation and experience, each causing significant amounts of waste (muda). By understanding how these inhibitors affect the product development lean principles, the course of transitioning to lean can be illuminated. The system effects of the barriers and inhibitors are also described using system dynamics. Finally, conclusions are developed in order to guide the company in its quest to become lean in product development and throughout the entire enterprise. by Laura A. Garza. S.M.

Includes bibliographical references (p. 105-106). Lean Manufacturing is widely accepted as a proven method to achieve operational excellence. Many manufacturers undertake lean manufacturing implementations as a strategy to improve competitiveness and realize business objectives. However, despite the wealth of literature on the success of lean manufacturing, it should not be viewed as a panacea for every business situation. A key challenge is to estimate the true benefits that a lean implementation is likely to provide, and compare them to the requirements of the business. This thesis provides a framework for such an analysis in the context of the Detroit Forge facility of American Axle & Manufacturing, Inc (AAM). AAM has been facing some significant challenges in the recent past, including skyrocketing steel prices, the prospect of declining sales and contractually fixed labour costs. AAM has launched a corporate wide lean manufacturing initiative to eliminate waste from its plants, and to make them more competitive. The actual improvement achievable at each plant will vary depending upon the current state of the plant, the nature of the operations and type of equipment used. (cont.) If the expected improvements do not satisfy the business requirements, options beyond the realm of pure operations must be considered, and are referred to as strategic alternatives. The analysis begins by characterising the current state and developing a vision of the future state using the tool of value stream mapping. We develop a model that predicts necessary supermarket buffers, changeovers and working hours as well as the associated costs, based upon fundamental process and plant parameters. The model is applied to the current and future states to predict the financial improvements that could be achieved by the lean initiative, based on the current cost structure of the operation. Finally we propose a framework for developing and analysing possible strategic alternatives to achieve the business goals. A wide range of alternatives was considered, including technology development, labour agreement renegotiation, outsourcing and optimisation of plant loading. This project resulted in the implementation of a pull scheduling system in axle shaft manufacturing, as well as input to the revitalisation efforts at Detroit Forge. by Dhananjay Ramaswamy. S.M.

Improvement in emergency CT brain workflow should reduce waiting times for CT scans resulting in earlier diagnosis and treatment of these patients. Identification of the nonvalue-added waste (NVAW) (steps regarded as wasteful to the customer) in the CT brain workflow can be determined by use of a lean management tool namely a value stream map (VSM - a flow analysis of information required to provide service to the customer). AIM: The study aims to identify non-value-added waste in the CT brain workflow value stream map which may result in delay in emergency CT brain reporting. Method: This study investigated NVAW in emergency CT brain workflow for 5 working days between 08h00 to 22h00 from Monday to Friday. Nineteen patients booked for an emergency CT brain scan by the Emergency Department (ED) only between 08h00 and 22h00 over the specific 5 day working period were randomly selected using convenience sampling. The indications for emergency CT brain scans in the sample were similar to the wider group of patients undergoing emergency CT brain scans. A VSM identifying all the relevant steps in the emergency CT brain workflow was constructed. The investigator accompanied each of the nineteen patients from the ED to the CT scanner and back and manually recorded the time elapsed in minutes for each separate step on the data collection sheet. The outstanding information required was obtained from the Xiris system on the Phillips PACS (Picture Archiving and Communicating System). The average time interval for each of the steps as indicated on the VSM was calculated, and the rate limiting step(s) which resulted in a delay in emergency CT brain reporting was identified. Results: Overall, the longest step was the time interval from the time of completion of the scan to the generation of the report (turnaround time (TAT)) with an average time of 72.21 minutes (p value of < 0,01). Conversely, the time interval from placing the request by the clinician on the PACS to the time of annotation by the radiologist was the shortest with an average time of 5.84 minutes. Discussion: The lean management system was used to identify the rate limiting step(s) which resulted in delay in emergency CT brain reporting. Possible reasons identified for the delay caused by the rate limiting step include the backlog in reporting of the large number of already scanned cases which may be due to staff constraints as only one radiologist was on duty during most of the study period. Additional contributory factors include clinician telephonic query interruptions to radiology registrars during reporting sessions and delay in the emergency doctor authorising and facilitating transport of the patient from the emergency unit to the CT scanner. Conclusion: The value stream map tool in lean management can be utilised to identify non value added waste in emergency CT brain workflow.

Abstract:

Several studies have found that traditional design planning to be unreliable and a cause of workflow variability during design development. The reason given for this is that traditional design planning lacks a mechanism to control workflow. Other studies have shown that the Last Planner system (LPS) of production planning and control reduces workflow variability during the construction stage of building projects by increasing planning reliability through greater collaboration in the planning of construction tasks and better coordination of work between the building trades. It is believed that LPS can also reduce workflow variability during the design stage by increasing planning reliability through greater collaboration in the planning of design tasks and better coordination of work between the design disciplines. In recent years, there has been a move toward collaborative and coordinated working practices in design firms, which has necessitated the formation of architectural/engineering (AE) firms, where all the design disciplines are involved in developing a design, aided by Building Information Modeling (BIM) tools. It is believed that, as processes that promote collaboration and coordination, LPS and BIM can be combined to improve design workflow beyond the degree to which it might be improved by the application of either of these innovations independently. It has also been suggested that there are synergies between Lean and BIM that can be exploited during design development to remove waste, reduce workflow variability and thus improve design workflow. These theories need further testing. Using action research (AR) and working closely with thirty-three design practitioners, the researcher facilitated the implementation of LPS weekly work planning (LPS WWP) and the realization of lean principles through BIM during the design development phase of a seven-story hotel and a six-story apartment at two different AE firms in Florida. Implementation of LPS WWP focused on increasing planning reliability to reduce workflow variability. The realization of lean principles focused on reducing waste in the BIM process through greater collaboration and better coordination between the various design disciplines. A Lean/BIM interaction matrix developed by Sacks et al. (2009) was used as a framework for exploring positive interactions between twenty-four lean principles and seven BIM functionalities. Percent Plan Complete (PPC) measurements taken before and after the implementation of LPS WWP suggest that LPS WWP was effective in improving workflow in both design projects: PPC increased by an average of 12.1% in the hotel project and by an average of 13.9% in the apartment project after LPS weekly work planning was implemented, representing an upward trend in PPC and continual improvement in design workflow. Eight lean principles were realized through the seven BIM functionalities used in both design projects, resulting in thirty-three discernible positive interactions in the hotel project and twenty-nine discernible positive interactions in the apartment project and contributing to the overall improvement in design workflow. This research has demonstrated that LPS WWP can reduce design workflow variability by increasing design planning reliability and that lean principles can be realized through greater collaboration and better coordination between the various design disciplines during the BIM process to reduce waste and improve design workflow during design development. It recommends that future implementation of LPS in design projects should consider LPS at the WWP level only and during the design development phase only. It also recommends that BIM should be used during design development as a design tool and not just as a visualization tool so its lean potential can be fully exploited. Further research is suggested for identifying and addressing causes of variability in design workflow other than poor design planning.

Cataloged from PDF version of thesis. Includes bibliographical references (pages 116-121). The long development lead time and high R&D costs for biologics drugs makes it imperative to eliminate delays and inefficiencies. Limited process development capacity can lead to delays in the availability of life-saving drugs and a large opportunity cost for biopharmaceutical companies. This study investigates the combined viability and impact of two approaches, namely applying lean principles and using high-throughput technology to increase capacity and productivity in pivotal biologics drug process development. Specifically, the project will explore a framework for improved handoffs and work design, and propose management systems to sustain implementation. In parallel, the study tests the sensitivity of the process development cycle to various resource constraints through a discrete event simulation and develops heuristics for the effective use of high-throughput equipment in upstream and downstream processes to increase process development capacity. The two approaches identified a potential increase in throughput of 2.75X (+175%) in preparation for an anticipated 2.3X (+129%) growth in biologics program demand in pivotal process development. by Maria Dominique Bautista Rustia.

Abstract:

A primary role of the Incident Command System is to learn from past incidents, as illustrated by its origins in the wildland firefighting community. Successful emergency response operations under the Incident Command System has prompted its nationwide spread, this promulgation critically relies on the system’s capability to stabilize and continuously improve various aspects of emergency response through effective organizational learning. The objective of this study is to evaluate the potential to apply fundamental principles of the Toyota Production System (Lean manufacturing) to improve learning effectiveness within the Incident Command System. An in-depth review of literature and training documents regarding both systems revealed common goals and functional similarities, including the importance of continuous improvement. While these similarities point to the validity of applying Lean principles to the Incident Command System, a focus on the systematic learning function of the Incident Command System culminated in the discovery of gaps in approaches proposed by the Incident Command System framework. As a result, recommendations are made for adjustments in systematic problem solving to adapt Lean principles of root cause analysis and emphasis on standardization of successful countermeasures to benefit the system. Future recommendations are also proposed based on the author’s understanding of the system.

During any time of reorganization, it is important to look to processes and practices that have been used and proven effective by other organizations whether those organizations are similar in structure or similar in the transitory environment in which they are operating. For this reason, applying Lean Enterprise principles and practices that have been proven in both industry and governmental organizations can be of great benefit to the Acquisition Directorate of the United States Coast Guard as it reorganizes to improve mission execution. Notwithstanding that when most people hear the words "Lean Enterprise" they immediately think of enterprises involved in manufacturing or supply chain effectiveness, the principles of Lean Enterprise thinking can also be applied in the service and support environments. Therefore, the Coast Guard Acquisition Directorate, a service enterprise, can apply these same principles and practices in an effort to transform the directorate into a Lean Enterprise. In this thesis, the Coast Guard's Rescue 21 project was used as an example for the entire Coast Guard Acquisition Directorate. The Rescue 21 project consists of the acquisition of a new advanced command, control and communications system to replace the antiquated National Distress and Response System (NDRS). From the application of Lean Enterprise evaluation approaches to the Rescue 21 project, it was evident that: (cont.) * The Rescue 21 project provides low value to its various stakeholders; * This low value is a direct result of cost overruns and schedule delays; * Misalignment exists among Strategic Objectives, Stakeholder Values, Key Processes and Metrics; * The Rescue 21 enterprise architecture has a solid foundation to improve value delivery; * The Rescue 21 project leadership desires to improve in the area of value delivery to stakeholders. by Andrew J.

Abstract:

The world has become more competitive, complex and unpredictable, and this process is continuing. Evolution is taking place resulting in organisations being pushed by strategies and pulled by increasingly assertive customers who demand more accountability and responsiveness (Kartte, 2010). In order to remain competitive in this changing world, many organisations, even financial institutions have adopted Lean principles in order to eliminate waste, reduce cost and streamline everyday processes (Spear, 2012). There have however been a number of challenges that have prevented financial institutions from implementing Lean principles successfully. The primary objective of this study is to improve the effectiveness of Lean principles within a specific financial institution. More specifically, this study will identify the effectiveness of successfully implementing Lean principles at a financial institution by investigating the influence of employee knowledge, understanding and skills, communication, motivation and ownership from management, organisational culture and the impact of trade unions in organisations as mentioned in the problem statement above. Convenience sampling was used to select a sample of sixty eight (68) employees within the specific financial institution. The sample was stratified to include senior managers, managers, team leaders and lower level employees. Questionnaires were distributed personally to the focus groups from the above categories.

Abstract:

Bibliography: leaves 170-174. The study emanated from the needs for (i) effective management systems in the currently changing South Africa, (ii) empirical, "real world" research in the operations management field as well as (iii) the requirement by local management to verify the effects of an implemented intervention. In terms of this background, the study investigates the effects of the implementation of lean Production principles in a South African Government-owned Rail Refurbishing Plant with a Job production system on financial performance as measured by Return On Investment (ROI). The research question formulated for the study investigates the possible differences in financial performance as measured by ROJ between the Transwerk (Bloemfontein) Rail Refurbishing plant, which implemented lean Production Principles, and three similar Transwerk Rail Refurbishing plants which had no lean implementation initiatives. The literature review discusses the constructs Lean Production and Return On Investment (ROI). Emphasis is placed on the elements and transferability of lean Production, as well as the proven and potential effects of lean Production principles on ROI. Despite cited criticism of lean Production, the overall conclusion was reached (on the basis of case studies, research and postulations) that the implementation of Lean Production principles in a South African, Government owned, Rail Refurbishing plant with a job production system can improve ROI The research design (a case study) is reviewed next. Data sources are identified to be financial statements and questionnaires, while data collection methods are listed as the documentary approach and the survey approach. Sampling is non-random, and the generalisation of results is listed as a potential weakness of the study. The richness of in-depth descriptions of lean Production principles as applied in the case study plant accompanied by descriptions of results and obstacles encountered, however, are listed as strong points of the study. A MANOVA is chosen as an appropriate statistical test to evaluate the collected data with α = 5% to answer the research question of the study, while two χ² tests are performed to answer the secondary questions.

Abstract:

This thesis examines and develops a proposed manufacturing system methodology and quality control for the design, planning, scheduling and implementation of the Thermiculite 866 high volume manufacturing line, through the use of Lean Manufacturing, Total Quality Management and Change Management principles. The concept under investigation extends to the analysis of flow production benefits and restrictions considering specific characteristics of the product. A novel factory design methodology is proposed to achieve required production volumes and cost effective implementation. Furthermore, high product quality levels are warranted by developing a Strategic Alignment of Quality Function Deployment which brings commercial awareness to the early stages in the product/process development, and reduces the time to market it whilst promoting long-term solutions. The process and the layout design are supported by a proposed Batch/Flow Comparative Matrix. As a result, the proposed factory design methodologies and management of change introduced in the organization led to a successful production system design as well as controlled implementation according to stakeholders requirements. The design and partial implementation of the Thermiculite 866 production line illustrates the effectiveness of the methodology proposed in this thesis to manage and design the equipment and quality for the future Thermiculite production line.

~ 3 ~ Abstract Master Program in Business process and Supply Chain Management Degree Project in Logistics 15 hp, Course 4FE06E Authors: Alexandra Dagberg, Alexander Thorén, Giovanni Tozzi, Kalin Velichkov Tutor: Roger Stokkedal Examiner: Helena Forslund Title: “Minimizing the risk of material shortage and waiting times via an improved order to delivery process – A study conducted within IV Produkt in Växjö” Background: Inventory Management activities have gained a relevant importance over the time in reducing uncertainties at both upstream as well as downstream levels of the supply chain, allowing a smooth material flow between chain members while responsively meeting customer demand. Control activities over the inventory represent a challenged and controversial aspect for most of today’s companies, including IV Produkt. Problem discussion: IV Produkt has, due to the rapid growth during the last ten years, fallen behind the area of inventory management as well as internal material handling process. The reason is that the company has not been able to develop these functions with the same pace as the economic growth. Consequently, the firm is facing difficulties to efficiently supply assembly lines, causing material shortage and waiting times. Research questions: RQ1: - How is the order to delivery process, from material supply functions to the Assembly line 2, at IV Produkt built up today? RQ2: - How can the order to delivery process of raw material and semi-finished products, between material supply functions and the Assembly line 2, be improved in order to minimize the risk of material shortage and waiting times? RQ3: - How can the physical storage of raw material and semi-finished products be structured within the studied area in order to support RQ2? Method: This thesis represents a descriptive case study conducted via a positivistic perspective and a deductive approach. Data was collected by interviews, observations and questionnaires, as well as via academic literature procured via a research in Linnaeus University’s library and via the use of approved web databases. Results are based on quantitative data collected from the studied company, guaranteeing the scientific credibility of the thesis. The respect of ethical principles were ensured by a discussion with company to mutually agree on the confidentiality of the presented information. Conclusion: The conclusion shows how the studied order to delivery process is built up today, highlighting several kind of waste in the current material and information flows. As a result, several actions, such as an extended use of the data system, the application of Kanban and the implementation of the ABC logic, in combination with a new proposed storage layout, were identified and proposed in order to minimize the risk of material shortage and waiting times.

Includes bibliographical references (p. 86). Classical manufacturing work cells have machines to perform each operation in the process, the number of each type of machine being chosen so that all machines would be equally busy. Although design of work cells for producing one product is straightforward, the design of a multi-product work cell is much more complex. Each product might require different machinery or require different processing times per operation, which complicates leveling the workload between machines. The decision of what type of machinery to purchase for a particular operation can be complex in itself when comparing a number of technologically different alternatives. Although the machines' operating characteristics might be well known, it is often difficult to understand how each technology will affect the overall production system. Any new work cell implementation is bound to cause friction within the organization. Change must be properly managed if it is to be done correctly. To implement any new structure for a work cell, both management and hourly employees must learn a new way of doing things. Often these new methods encounter significant resistance if not implemented in a way that takes into account their cultural impact. (cont.) This thesis describes a method for designing multi-product manufacturing work cells that utilizes optimization techniques to select capital machinery and uses Lean principles to assemble the machinery into an efficient and effective unit. It also shows how the best machinery for an operating environment can be chosen from two competing technologies. Finally, the thesis describes methodology for implementing new work cells in a change-adverse culture.

With engine and auxiliary power unit (APU) growth of-9% in 2005, and projected growth similar or greater for 2006, however, some segments of the business are experiencing difficulty in delivering engines on time to customer request dates. In the spirit of Lean Enterprise, Honeywell must to deliver value to its customers by stepping back and analyzing the entire value stream. Enterprise-level optimization of supply chain, assembly, and test practices will lead to the greatest benefit to both internal and external stakeholders. This thesis explores the issues within one segment of the Aerospace business - specifically, new engine and APU deliveries -- as well as internal initiatives to drive high quality and lean manufacturing. A Lean Enterprise Self Assessment Tool survey was conducted to highlight opportunities to propel Honeywell to a culture of high performance. Both high-level multi-million dollar opportunities, as well as low-budget, improved processes and communication initiatives will be discussed. Ultimately, the Honeywell Aerospace Engine Assembly and Test Center of Excellence must sacrifice narrow use of lean tools for wide ranging promotion of lean principles, thereby improving the overall value delivery to all enterprise stakeholders. by Andrea Jones.

Abstract:

Bakgrund och problemdiskussion: Ökad konkurrens sätter press på företag att vara anpassningsbara och utveckla sina verksamheter vilket har resulterat i att fler företag, framförallt tillverkande, infört Lean Production (LP) på grund av dess potential att stärka produktionseffektiviteten. Tidigare forskning menar att den traditionella verksamhetsstyrningen och ledarskapet inte stödjer användandet av LP och är i behov av att anpassas för att stödja de förändringar som LP-strategin innebär. Tidigare forskning har vidare inte haft svenska företag som sin utgångspunkt vilket skapar intresse om tidigare identifierade effekter på hur LP påverkar verksamhetsstyrning och ledarskap även går att bevittna i svenska tillverkande företag. Syfte: Syftet med denna studie är att beskriva samt analysera de effekter och utmaningar som kan identifieras i en övergång mot LP på verksamhetsstyrning och ledarskap bland några svenska tillverkande företag. Metod: En kvalitativ flerfallsstudie på fyra svenska tillverkande företag: Emballator Lagan Plast, Emballator Växjöplast, Glamox Luxo Lightning och Gårö Plåtprodukter. Teorin underbyggdes av relevant litteratur, vetenskapliga artiklar och sekundärkällor, samt tidigare empirisk forskning. Empirin hämtades in genom semistrukturerade intervjuer på plats samt observationer. Slutsats: Samtliga fallföretag har genomgått förändringar som följd av LP, med vissa genomgående karaktäriserande drag men även förändringar som skiljer sig emellan företagen. Utifrån analysen har det gått att se att LP frambringat flertalet effekter bland fallföretagen på verksamhetsstyrning och ledarskap där de flesta har liknelser med tidigare empiriska studiersresultat. Dock har andra effekter identifierats, bland annat den ökade mognadsgraden hos ledarskapet och hur den påverkat utformningen av verksamhetsstyrningen och de LP principer som införts. Ytterligare har även framtida utmaningar med LP identifierats. Background and problem discussion: Increased competition on the market puts pressure on companies to be adaptable and develop their operations which has resulted in that more companies, especially within manufacturing, has introduced Lean production (LP) as a way to streamline and improve their operations. Previous research argues that the traditional view of management control and leadership does not support the use of LP and needs to be adapted to support the changes resulting from the LP strategy. Previous research has furthermore not focused on exclusively Swedish companies which makes it interesting to see if previously identified effects on management control and leadership caused by LP also can be identified in some Swedish manufacturing companies. Purpose: The purpose of this study is to describe and analyze the effects that can be identified in a transition toward LP on management control and leadership among some Swedish manufacturing companies. Method: A qualitative multi-case study of four Swedish manufacturing companies, Emballator Lagan Plast, Emballator Växjöplast, Glamox Luxo Lightning and Gårö Plåtprodukter. The theory was supported by relevant literature, scientific articles and secondary sources. The empirical data was retrieved through semi-structured interviews and observations. Conclusion: All case companies have undergone changes as a result of LP, with some consistently characterizing traits but also changes that differ between the companies. Based on the analysis, it has been possible to identify several effects regarding the companies leadership and management control due to LP, where some have previously been identified in other empirical studies. However, other effects have also been identified, including the increased maturity of leadership and how it has influenced the design of management and control within the case companies and the LP principles they introduced. Furthermore future challenges regarding LP have also been identified.

O presente trabalho propõe um modelo de gerenciamento de projetos, baseado nas metodologias ágeis de desenvolvimento de software (Extreme Programming e o Scrum), e nos princípios e valores do pensamento enxuto, originado na manufatura automobilística japonesa. Após a proposição do modelo, ele é aplicado em um estudo de caso, avaliando os resultados obtidos na combinação entre as metodologias ágeis e nos princípios e valores da produção enxuta. Em seguida, este modelo é analisado qualitativamente com o intuito de determinar suas vantagens de utilização e seu escopo de aplicação. Para tanto, recorreu-se a uma avaliação do modelo proposto e o tradicional modelo cascata, ainda amplamente adotado no setor de software, e mapeando como este modelo contorna os problemas apontados na literatura, advindos da utilização do modelo cascata. Looking for sustainable gains in productivity and quality in the development of software, several models, forms of work organization and innovative approaches were developed to support software development managers. The present work proposes a model of project management, based on agile software development methodologies (Extreme Programming and Scrum) and on lean principles and values borrowed from the Japanese automobile manufacturing. After describing the proposed model, it is applied in a case study, describing the results of combining the agile software development methodologies with the lean production principles and values. After this, the model is qualitatively analyzed to determine its advantages and its scope of application. For this, the proposed model is evaluated with the traditional waterfall model - until now widely adopted in the software industry - and mapping how it addresses problems, cited in the literature, derived from the use of the waterfall model.

Abstract:

Bakgrund: Lean management är en administrativ reform som gör anspråk på att ständigt förbättra och effektivisera för att förbättra kvalité inom flera sektorer, varav en är sjukvården. Ett sjukhus som arbetar med Lean Management för att förbättra sin vård är S:t Görans sjukhus. Vid design och utformning av ombyggnationerna inom Sjukhuset har Lean används. Det finns väldigt lite forskning utfört om Lean och design inom vården Syfte: Studiens syfte är att studera Capio S:t Görans sjukhus arbete med Lean management och om det organisatoriska arbetet har influerat designen samt utformningen av sjukhusets nya vårdlokaler. Metod: Kvalitativ ansats med ett bekvämlighetsurval har använtsför att utföra studien. Observationer och intervjuer gjordes på S:t Görans sjukhus akutmottagning och Medicincentrum. Empiri och Analys: Intervjun och analysen presenteras i fem olika teman utifrån observationen som gjordes och intervjuerna. Empirin har bearbetats genom en innehållsanalys och analyserats med den teoretiska referensramen. Studien visar på att Lean management har influerat utformningen av de nya lokalerna. Främst kan det ses i undersökningsrum och hur patientens väg genom mottagningen ser ut. Det går även att se att inställningen till hur en sjukhusmiljö skall se ut är svår att bortse ifrån vid design och utformning av nya sjukhusmiljöer. Slutsats: Lean management principer kan uppfattas i de nya lokalerna. S:t Görans sjukhus kan anses ha lyckats med att utforma sina nya vårdmottagningar med hjälp av det redan förankrade arbetssättet. Avslutande kommentarer: I avslutande kommentarer diskuteras analysen och slutsatser, men även metodval och slutligen lyfts det fram vikten om mer forskning inom detta område.

Abstract:

Thesis (M.B.A.)--Massachusetts Institute of Technology, Sloan School of Management; and, (S.M.)--Massachusetts Institute of Technology, Engineering Systems Division; in conjunction with the Leaders for Manufacturing Program at MIT, 2009. Includes bibliographical references (p. 94). Global Automotive, a large US based, global manufacturer of automobiles, has made significant gains in manufacturing competitiveness, in part through application of a lean manufacturing approach to high volume assembly. A similar approach applied to product development can result in significant improvements in product design throughput, speed, cost, design quality, and innovation. With major product programs taking in excess of 36 months and a billion dollars to complete, the potential impact of process improvements is substantial. This thesis examines elements of Global Automotive Product Development Process. Some general guiding principles for Lean product development are also reviewed from the existing literature. Special attention is given to metrics for measuring product development performance at Global Automotive. The thesis focuses on the role of peer reviews in the development process. The analysis is performed using a work order data set for two automotive development programs. Score cards from Peer Review and a survey of the component engineering community are also used to assess the effectiveness and current state of the peer review process. The study found evidence that high scores on peer reviews do not guarantee that late changes will occur, if anything component groups with average lower scoring peer reviews generated led to consistent levels of late stage changes. The objective of peer reviews should clearly be to find as many problems as possible and participants should be encouraged to delivery "low scoring" reviews.

Abstract:

Research has shown that the focus of mathematics student teaching programs is typically classroom management and non-mathematics specific teaching strategies. However, the redesigned BYU student teaching structure has proven to help facilitate a greater focus on mathematics-specific pedagogy and student mathematics during post-lesson reflection meeting conversations. This study analyzed what specific principles of NCTM’s standards of effective teaching were discussed in the reflection meetings of this redesigned structure. This study found that the student teachers extensively discussed seven of the eight principles NCTM considers to be necessary for effective mathematics teaching. Other pedagogical principles pertaining to student mathematical learning not included in NCTM’s standards of effecting teaching were also discussed, as well as the student teachers’ own understanding of mathematics. Behavior was discussed very little. This study also provides insights into how mathematics student teaching can be further restructured to assure that mathematics student teachers can leave their student teaching programs ready to implement the principles of effective teaching in their own classrooms.

Abstract:

In today’s challenging business environments, competitive advantage is of utmost importance for organizations and there is a raising demand for profitable solutions that allow organizations to gain competitive advantage. Two of such profitable solutions are Project Management (PM) and Lean Thinking, recognized methodologies for management and production processes. This dissertation proposes a framework to accelerate the performance of projects through PM practices and lean principles. To develop the framework, Project Management Officers (PMOs) of renowned Portuguese companies are interviewed. In the first Stage, interviews are conducted aiming to identify key pain points in PM. Resulting from the first set of interviews, lean principles are applied to PM to remedy the identified pain points and develop a Lean Project Management Framework. The interviews identify the most critical knowledge areas in terms of pain points as Human Resources, Scope, and Procurement Management. In the second stage, experts’ feedback is used to validate the developed framework on four pillars: degree of understanding, alignment towards the major pain points, practical applicability, and orientation towards the final result. All the respondents conceded that the newly developed framework considered the major pain points and was oriented towards the final result, projects success. Nevertheless, some respondents considered that up-front lean knowledge is needed and suggested the development of a framework dictionary to improve understanding and practical applicability. The findings show that the use of traditional lean tools adapted to the PM context can aid in the continuous improvement of processes and practices by conferring role clarity, transparency, and reducing bottlenecks. The Lean Project Management Framework provides a viable approach to overcome the shortcomings of traditional PM practices. Nos desafiantes ambientes de negócio atuais, a vantagem competitiva é essencial para as organizações, havendo uma constante necessidade de encontrar soluções que permitam às organizações obter vantagem competitiva. A Gestão de Projetos e o pensamento Lean são duas destas soluções, reconhecidas nas vertentes de gestão e de ambiente de produção. Esta dissertação propõe um modelo para alavancar o desempenho dos projetos através de práticas de Gestão de Projetos e princípios Lean. Para desenvolver o modelo, são entrevistados PMOs ("Project Management Officers") de empresas portuguesas reconhecidas. Numa primeira fase, as entrevistas visam identificar as principais dificuldades na gestão de projetos. Como resultado destas entrevistas, os princípios lean são aplicados à gestão de projetos para mitigar as dificuldades identificadas e desenvolver um modelo lean de gestão de projetos. As entrevistas identificaram as áreas de conhecimento de Recursos Humanos, Âmbito e Contratação, como as mais criticas em termos de dificuldades. Na segunda fase, a opinião de peritos é utilizada para validar o modelo em quatro pilares: nível de compreensão, principais dificuldades, aplicação prática e orientação ao resultado final. Todos os entrevistados concordaram que o modelo considera as principais dificuldades de gestão de projetos e tem orientação ao resultado final, o sucesso dos projetos. Contudo, alguns entrevistados consideram necessário haver conhecimentos prévios de princípios lean e sugerem o desenvolvimento de um dicionário para o modelo, para melhorar a sua compreensão e aplicação prática. Este estudo demonstra que o uso das ferramentas lean tradicionais adaptadas ao contexto de projetos pode auxiliar na melhoria continua de processos e práticas, conferindo clareza, transparência e reduzindo constrangimentos. O modelo lean de gestão de projetos - "Lean Project Management Framework" - fornece uma abordagem viável para superar as deficiências das práticas tradicionais de gestão de projetos.

Abstract:

碩士 嘉南藥理大學 醫務管理系 106 The collection and inspection of surgical pathology specimens is a key medical task in the operating room (OR). Such specimens provide physicians with a referential basis for diagnosis and treatment. The collection of surgical pathology specimens is an invasive procedure, during which patients are at risk of bleeding, infection, and even death. The integrity of surgical pathology specimen inspection is crucial to patients’ safety, and any missing links may affect their diagnosis and treatment. Furthermore, reexamination of missing specimens puts patients at greater risks related to invasive examination. The incomplete inspection of pathology specimens increases human resource usage. Thus, medical care requires the introduction of stricter norms; establishment and practice of correct collection, storage, and transportation of surgical pathology specimens; elimination of mistakes in the process; reduction of specimen rejection rates; and reduction of treatment risks. Current OR processes are characterized by multiple risks, a high level of wastage, and ineffective actions. Therefore, a proven method must be used to address existing problems. It is thus necessary for lean thinking—normally used in the manufacturing industry—to be implemented in medical care to address methods that are risky and cause process waste. Accordingly, this study explored the use of lean healthcare in surgical pathology specimen inspection implemented through smart technologies. The research objective was the use of lean healthcare by a medical center for surgical pathology specimen inspection. In-depth interviews, field observations, and relevant secondary data collection methods were used to explore informatization and the application of surgical pathology specimen inspection from the perspective of lean healthcare, as well as benefits and obstacles in systematic development. Data were analyzed and discussed using the content analysis method. The data analysis results can be summarized according to five lean principles: 1.Specify value: The value of treatment activities related to surgical pathology specimens is patient safety, which must be ensured and protected in the process of relevant inspection. The correct actions and timing can reduce delay- and mistake-related risks. 2.Identify the value stream: The confirmation of the value stream, including the informatization of the surgical pathology specimen inspection process, can contribute to cooperation within surgical teams and reduce complications related to traditional manual processes, paper waste, and other waste and errors. Information management tasks include the informatization of all operations related to list compilation, pathology specimen collection, and inspection completion. On-the-job education and systematic testing can be provided to ensure the effective collection, delivery, and management of information in the overall process. This can reduce process-related waste and increase the safety of operational processes because of an absence of man-made mistakes, thereby transforming the current unfavorable situation into a more ideal value stream. 3.Flow: Three core steps exist in flow establishment. The first is to perform an overall examination of the design of surgical pathology specimen inspection from beginning to completion in order to determine problems influencing the flow. The second step is to solve current issues and conduct on-the-job education regarding the informatization of the inspection process. A quality management center performs problem analyses, proposes improvement methods and problems occurring in the intervention of information seeds, and determines specimens for 30-minute laboratory registration and inspection. The safety protection mechanism used in specimen inspection includes a careful examination of inspection operations, which transforms the service line into a continuous flow. The final step involves rethinking specific work methods and tools to exclude repetitive and canceled processes. Thus, necessary technologies, special pathology-related facilities, and operational process norms can be established according to relevant informatization needs to avoid process waste. 4.Custom pull: The matching processes to patient needs include the coordination of patients’ pathological reports from various departments and adjustment of the specimen stream. Processing of surgical pathology accounting must be adjusted according to emergency outpatient and inpatient needs to ensure the integrity of the specimen inspection accounting procedures. 5.Continuous improvement: Problems related to the informatization of pathology specimen inspection must be addressed and solved by individual units through continuous monitoring of surgical pathology specimen quality. The practical application of lean principles in this study effectively reduced process-related waste. Smart technologies were effectively used to monitor patient safety. The use of lean thinking was explored to improve the quality of surgical pathology specimens without increasing the use of human resources as well as to avoid process waste. The results can provide a reference for organizations currently or prospectively engaged in developing lean healthcare.

Abstract:

Lean principles emerged in the Japanese manufacturing industry after the Second World War. Lean management focuses on improving product quality while eliminating waste—primarily through process redesign and the integration of employees, management, suppliers and customers into the quality management process. The NHS is under significant pressure to improve productivity while maintaining or improving service quality, at the same time as service demand increases. The Quality, Innovation, Productivity and Prevention (QIPP) programme’s primary concern is to ensure that financial resources are used to bring maximum benefit and quality of care to patients (Department of Health, 2010). Lean management could therefore offer a panacea for the NHS, although its applicability to the health service sector is contested. This article investigates whether lean management is merely a fad or whether it could alleviate the pressure the NHS faces. While specific clinical processes may easily adopt lean processes and practices, healthcare organisations will need a paradigm shift in their management philosophy to adopt lean more widely. The promise of lean management remains elusive but could be harnessed by willing organisations.

Abstract:

A research report submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the Degree of Master of Science in Engineering, October 2015 A single case study of a major third party logistics provider (3PL) in South Africa was completed for this research. A total of four warehouses, including 43 workers partook in the study. The primary objective of this research was to determine how well employees within the warehousing industry understand Lean principles, and to illustrate the gap in Lean knowledge between the employment levels, i.e. Managers, Supervisors and Material Handlers. Group-administered questionnaires were used as the principle means of gathering data. All participants for each respective warehouse were present in a “classroom” format during completion of the questionnaires. The author was also present during all sessions to ensure consistency and to clarify any questions that participants had. The questionnaire tested each participant’s understanding with regards to seven key Lean principles in warehousing. These seven principles were identified from previous research on Lean within warehousing. The results gathered from the questionnaires were then validated using semi-structured follow-up interviews. It was found that a real gap in Lean knowledge exists between Managers and Material Handlers (shop-floor workers). Managers understand the key Lean principles within warehousing, as well as the importance thereof. While the employees actually working on the floor do not. The main reasons for this are due to a lack of suitable training and knowledge sharing. Based on the seven key Lean warehousing principles, the following were identified in the study as the most important ones to focus on: Continuous Improvement and Visual Management. These are believed to be basics in warehousing. However, employees still seem to struggle with the true understanding and significance thereof. It is imperative that the understanding of Lean principles and the involvement of management exist when striving to be successful with Lean. The gaps in Lean knowledge have been identified and laid out in this report. The reasons for each gap have also been investigated and discussed in detail. Finally, pertinent areas have been highlighted to assist with the development of Lean training material. This will ensure that the current gap of Lean understanding among warehousing employees is closed.

Abstract:

A research report submitted to the Faculty of Engineering and Built Environment, University of the Witwatersrand, Johannesburg, in partial fulfillment of the requirements for the degree of Master of Science in Engineering. Johannesburg 2017 The purpose of this research was to investigate the effectiveness of Learning factories in imparting Lean principles in order to build Business Improvement skills of mining workforces. This study was conducted at a training centre established by a mining company in South Africa. Two groups of participants with employees at two different employment levels were trained at the centre in foundation Lean principles. The Kirkpatrick model for evaluating effectiveness of training was chosen as a tool that can be used to evaluate the effectiveness of this Lean training. This was achieved using before-and-after questionnaires, visual observations and process data from improvement projects identified by the participants. The results showed that the Learning Factory is effective in imparting the Lean skills across hierarchy levels in a mining operation within a short space of time. Furthermore, all employees arrived at the same overall Lean understanding post training regardless of their starting point. Where project implementation was done, it was found that the participants were able to apply most of the Lean principles in the workplace. A major shortcoming observed was that the main focus was on technical aspects of Lean with little regard for other aspects that contribute to sustainable Business Improvement such as change of culture. Lastly it was found that while the Learning Factory can assist in building Lean capability in an implementation, the other success factors such as management buy-in and workforce support can enhance this effort. One recommendation is to do a study to determine the interrelated nature of the factors that drive a successful Lean implementation and the role that a change management program like ADKAR can play to maximise success.
