Metodologie Six Sigma se dnes používá v mnoha firmách a společnostech ke zlepšování kvality procesů a výrobků. Využívá k tomu různé statistické nástroje a jedním z hlavních je lineární regrese. Cílem této práce je stručný popis metodologie Six Sigma. V dalším kroku pak pomocí lineární regrese ale i jiných statistických nástojů eliminovat jednu výrobní operaci v konkrétním technickém procesu.

The Focus of this mixed method research was the implementation of lean six sigma principles to improve productivity of outpatients’ programs where each case requires multiple scheduling, multiple visits to patients’ homes and multiple visits to the health department. The site is the Peoria City/County Health Department (PCCHD). The PCCHD is the delegate agency for Illinois Department of Public Health Childhood Lead Poisoning Prevention Program (EH). They are also a recipient of the Federal Lead-Based Paint Hazard Control (LHC) program from the Department of Housing and Urban Development (HUD). In line with their mission, they sought opportunities to review and streamline their lead abatement programs to improve productivity and effectiveness of service value offered to their recipients. This research analyzed the current state of lead abatement efforts in Peoria County and used lean six sigma methodologies to identify quantifiable opportunities to improve the effectiveness of PCCHD’s lead abatement efforts. Results show that through the use of lean six sigma methods, the lead time of the PCCHD lead abatement program Lead-Based Paint Hazard Control from the Department of Housing and Urban Development (HUD) was reduced by 30%. Secondly opportunities to eliminate duplication and omission of activities between lead abatement programs were identified and recommended. This research confirms that lean six sigma methods can also be applied successfully to more complex programs such as the lead abatement programs that require multiple scheduling, multiple visits to patients’ homes and multiple visits to the health department

ABSTRACT A GUIDE FOR CONSTRUCTION COMPANIES TO APPLY LEAN SIX SIGMA METHODOLOGY D&Uuml / gME, Fatma Zehra M.S., Department of Civil Engineering Supervisor: Asst. Prof. Dr. Yasemin NIELSEN April 2008, 245 pages The construction sector is an immensely important industrial sector in terms of economic and social impact and also employment facilities. Nonetheless, much research has pointed out a gap in terms of labor productivity, quality, performance and responsiveness to customer needs when compared with other large industrial sectors / sectors that have recently experienced huge gains and cost reductions via methods like Lean Six Sigma. In this study, the construction industry will be examined for determination of the potential Lean Six Sigma implementation level and expected benefits from its use. The author conducted interviews with three companies in order to find out their readiness for such a management by innovation. One of the companies was selected for further study due to suitability of their organizational structure, innovative strategy and interest in this study. By taking up this pilot study and Lean Six Sigma principles as references, five roadmaps are generated as a guidance to implement Lean Six Sigma methodology for companies indicating the general steps before and during the implementation. The proposed roadmaps and applied questionnaire/interview questions developed in this thesis will also be helpful to construction companies to scrutinize their own structure and performance levels and as a guide on how to pursuit improvements through the proposed implementation of the Lean Six Sigma methodology.

The Health Care System has struggled with many problems such as medical errors, poorly designed processes, waste, and customer dissatisfaction. The Lean Six Sigma methodology has been shown to be efficient in solving problems in the manufacturing industry and in services, as well. In this study, a framework for applying Lean Six Sigma to the health care industry is presented. The framework depicts a systematic methodology to solve problems typically found in this industry. A case study is also presented on how to apply this framework. The DMAIC Model has been conducted in an Imaging Department to identify the root causes of problems and to define a future state of the process

The diploma thesis describes practical usage of Lean Enterprise and Six sigma tools in Honeywell Brno o. z. The aim of this diploma thesis is to demonstrate Lean Enterprise and Six Sigma tools like one of the most effective tools of continous improvement in production.

The diploma thesis applies to Lean management and it´s application in administrative processes. The goal of diploma thesis is proposal to increase the value added activities and to reduce waste at the same time in the area of administration. The methods of Lean management as 7+1 waste, Kaizen, Lean office, Six Sigma and Lean Six Sigma are applied in administrative processes in Shared service centre. These methods are evaluated by performance and productivity of processes.

Competition and lead-time pressure motivates us to find new and better ways of continuously improving the output of our work. The emphasis on improvement in both efficiency and quality has become more and more significant in daily activities. The performance of Ericsson’s AXE/APZ products during shipment test phase is one such activity and is the focus of this thesis project. One of the essential principles of shipment testing is to ensure that the test campaigns finish on time. Over the last several decades companies have spent large amounts of time and money on improving test quality and efficiency. Unfortunately, the results have not always been as good as expected. It seems that it is very difficult to improve shipment testing performance using traditional test management methods. Motorola introduced Six Sigma in 1986 and achieved 5.4 Sigma level which help them saved 2.2 Billion dollars during the first six years. From Statistic aspect, it means only 3.4 defects per million opportunities. The Six Sigma methodology has been applied as a management philosophy focused on improving efficiency and performance during the shipment test period. This thesis gives an introduction to the Six Sigma approach, including the concepts of Six Sigma, its history, development, and methodology. More specifically the author uses the Define, Measure, Analyze, Improve, and Control (DMAIC) approach to evaluate the performance of Ericsson’s AXE/APZ Shipment Testing. This project goal was defined: Compare with the performance of 08AXE shipment test which 87% of test campaigns (2.68 sigma level) were finished on time, 3 sigma level in 09AXE shipment test which means 93%of the test campaigns will be finished on time has to be achieved.  The thesis measured the 08AXE shipment test performance and analyzed the lead time of test campaigns, found the root causes such as poor documents quality from the legacy project, lack of test resources, no system impact analysis. The thesis also provided a set of proposals for improvements and control of the improved process in order to ensure sustainable improved performance results. Finally 93% test campaigns were finished on time in 09AXE and project goal was fulfilled. / Konkurrens och ledtid tryck motiverar oss att hitta nya och bättre vägar att kontinuerligt förbättra resultatet av vårt arbete. Betoningen av förbättring av både effektivitet och kvalité har blivit allt mer signifikant i våra dagliga aktiviteter. Prestationen av Ericssons AXE/APZ produkter under sändningens test fas är en sådan aktivitet och det är där fokusen på detta tes projekt ligger. En av de grundläggande principerna av sändnings test är att se till att test kampanjer avslutat i tid. Under de senaste årtionden har företag spenderat stora summor tid och pengar att förbättra test kvalité och effektivitet. Tyvärr har resultaten inte vart så bra som förväntat. Det ser ut så att det är mycket svårt att förbättra sändnings test prestationen när du använder traditionella test förvaltningsmetoder. Six Sigma metodik har blivit tillämpad som en ledningsfilosofi fokuserad på att förbättra effektivitet och prestation under test exekverings perioden. Denna tes ger en introduktion till Six Sigma tillvägagångssättet, inklusive konceptet från Sig Sigma, dess historia, utveckling och metodik. Mer specifikt använder vi Define, Measure, Analyze, Improve och Control (DMAIC) tillvägagångssätt för att utvärdera prestationen av Ericssons AXE/APZ sändnings testning.  Denna process kräver definitionen av prestationsmålet, mätningar av nuvarande prestanda och analys av data för att hitta rötterna till orsakerna av problemen. Resultatet av denna definition, mätning och analys var en rad förslag till förbättringar och kontroll av den förbättrade processen för att säkerhetsställa hållbara förbättrade prestations resultat.

In a metal mechanic company dedicated to the manufacture of electrical boards which focus is the terraced boards there was presented a fulfillment rate failure to deliver on time 46%. On the other hand, the delivery delay is generated because the current productivity does not supply what is required by the customer, therefore a minimum 394 units per month is needed to meet the requirements but currently only produce 226 units per month. For solve this problem it was proposed that Production model that merges the painting and baking areas and that generates an impact on the entire painting operation.

Lean Six Sigma is an approach focused on improving quality, reducing variation and eliminating waste in an organization. The concept of combining the principles and tools of Lean Enterprise and Six Sigma has occurred in the literature over the last several years. The majority of Lean Six Sigma applications have been in private industry, focusing mostly on manufacturing applications. The literature has not provided a framework for implementing Lean Six Sigma programs applied to local government. This research provides a framework roadmap for implementing Lean Six Sigma in local government. The Service Improvement for Transaction-based Entities Lean Six Sigma Framework Roadmap (SITE MAP) identifies the activities, principles, tools, and important component factors to implement Lean Six Sigma. The framework provides a synergistic approach to integrating the concepts and tools of Lean Enterprise and Six Sigma using the DMAIC (Define-Measure-Analyze-Improve-Control) problem solving approach. A case study was used to validate the framework. Lean Six Sigma was successfully applied in a 7,000-citizen municipality to reduce the cycle time of the financial administrative processes in the Finance Department of the city government.
