The master´s thesis deals with the company engaged in providing services in IT. The main aim of the thesis is to map selected logistics chain of company and to use selected techniques of Lean Six Sigma for optimizing it. The first part of the thesis deals with the current situation on the market reverse logistics associated with electronics and legislative requirements for the supplying of warranty claims. The theoretical part introduces concepts of lean manufacturing and tools for the process mapping. The practical part has a goal with tools DMAIC to shorten the lead time of repair, to find waste and downtime it the service process, which have affect on the customers satisfaction.

The aim of this work is to determine a methodology to measure the leanness level of the organizations that have an internship in the framework of the minor specialization of Quality Management and Lean Six Sigma at University of Economics. The theoretical part of the Thesis presents issues of Lean Six Sigma methodology, describes basic characteristics and main Lean Six Sigma tools. The Thesis also describes process of a research, on which was applied the proposed measurement methodology of an internship impact on organizations. The research methodology describes leanness measurement approach, process of data collection and its subsequent analysis and evaluation. The last chapter includes conclusion of results, suggestions and recommendations to improve Quality Management and Lean Six Sigma Practical.

The aim is to use Lean Administration metodology to improve custom clearance process steps that do not add value, but it is necessary to carry out them due to legislative reasons. The company has excellent results of applying the Lean principles in manufacturing and this thesis will bring to the company specific application of Lean Enterprise metodolgy outside manufacturing. The thesis is proof of the implementation of the company philosophy of continuous improvement, perfection does not exist, there is always the possibility of improvement.

The aim of the thesis is to suggest recommendation to optimize and increase efficiency in a process of catering ordering in a company Express Deli by using methods of lean six sigma. The work is built as real project od lean six sigma using some methods of the methodology lean six sigma. In the theoretical part of the thesis, methods of lean six sigma used in the practical part, are described. These methods are mainly methods of process mapping. Each chapter is a step of DMAIC methodology. Core part of the thesis is process mapping at a customer side, so in the other part there are all recommendations directly focused on customers requirements. The results of the work are suggested proposals for process improvement. Some of them were implemented during the project.

Theses is devided into two parts, the first one is dealing with theory the other one with practical exercise. There is basic terminology set in the first part, focusing mainly on process management and methodologies leading the current evolution in that respect, Lean and Six Sigma. I also refer about tools for mapping the processes and devote a section to theory of queues which is a main subject for modelling in the practical part. I have not omitted to mention axioms for modeling itself. Practical part comes from job experience I had. Main goal is to set up a model simulation based on the main features of the process structure, involve main principles of mentioned methodologies and to discuss the results simulation brings.

The diploma thesis is focused on implementation of lean production through using Lean Six Sigma method into an engineering company, producing cable harnesses for the automotive industry, mainly for trucks. The aim of the project is to increase production capacity by 25 %, reduce wastage rate to 3 % and design a new layout of production areas. The budget of this project is 3 million CZK. The production was slimmed down using the 5S methodology. To meet the aim of the project, three new machines had to be bought. The steps have resulted in a saving of 64 CZK per piece, which means a return on investment in about 8 months.

This thesis is primary focused on optimization of the production process in a selected company.Teoretical part of this thesis is the result of literature research of Lean Six Sigma, which is mostly used by the company. It is a brief insight to an issue and introduction of the most often used tools from Lean Six Sigma methodology, which were used afterwards in practical part of this thesis. Also there is an introduction of the company and its production portfolio. Crucial part of this thesis is it‘s practical part focused on improving of current situation on the production line with an economical and technical assessment. The main goal was to create more compact and smaller area of product line with lower work in progress.

Description of present state of compressed air production in Motorpal a.s. Jihlava. Toll used for production procedure and output improvement, quality problems solving and improvement implemantation. Problem define, measure, analyse, iprovement proposals and improvement implementation, improved process control via Lean Six Sigma methodics.

<p>Lean Six Sigma (LSS) has been implemented worldwide for many years and has been successful in many organizations. Eloot, Huang, and Lehnich (2013) noted that achieving manufacturing excellence by using LSS was an opportunity for many companies. Liker and Rother (2011) pointed out that only 2% of companies successfully achieved the desired results with Lean plans. </p> <p>The presented dissertation identified the critical success factors of LSS implementation for Chinese manufacturing companies and explored the challenges occurring during the LSS transformations. The objectives of this dissertation were: </p> <p> i. to understand how the employee training process for LSS can be designed using total quality management (TQM) adoption in private manufacturing organizations in China;</p> <p> ii. to understand how LSS practices can be adopted successfully in SMEs in China;</p> <p> iii. to examine and explore the critical success factors (CSF) of LSS implementation;</p> <p> iv. to discuss the challenges occurring during LSS transformation.</p> <p> </p> <p>Objective (i) was achieved through a descriptive single case study. This case study showed how to apply <a>a design for Six Sigma methodology (DMADV) for staff training in quality management tools in a private organization in China</a>. The author also discussed the problems occurring during the Six Sigma project and explored how organizational culture impacted Six Sigma implementation. Objective (ii) was achieved through a detailed descriptive single case study which recorded how LSS practices were adopted successfully in a SME-VTCL in China using DMAIC methodology. Survey data was collected to identify and explore the critical success factors of LSS implementation in SMEs, by querying the voice of top, middle, and frontline management, as well as frontline workers of these companies. Objectives (iii) and (iv) were realized utilizing descriptive, exploratory, and multi-case studies designed to gather and analyze observational and interview data. The resulting interview data, and the key factors for successful LSS transformation of these three companies were discussed from the perspective of senior management and LSS promoters within the companies. Based on interview data and the Lean iceberg model, a new LSS transformation model was proposed. The author also developed 6 propositions based on the findings from the interviews. </p> <p>In summary, the results of this study provided value and references for LSS practitioners to expand the body of knowledge on the strategies used to implement LSS successfully inside organizations. The findings of this research may potentially lead more Chinese organizations to successfully adopt LSS to provide customers with high-quality products. The three LSS implementation cases described <a>critical success factors (CSFs)</a> and challenges that occurred during the transformation, may improve the success rate of implementation, help enterprises achieve the desired results through LSS, and enhance the sustainability of LSS implementations.</p>

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.
