The main goal of this thesis is to improve logistic processes at Anheuser-Busch InBev by aplying Lean and Six Sigma methods, in paticular, by using DMAIC methodology. Thesis is divided into two parts: theoretical and practical. In the theoretical part methods of Six Sigma and Lean are described and recent tendency to combine these methods together. Each step of DMAIC methodology was described in details in theoretical part. In the practical part there is a project which aims to of improveme international transport flows from England to Italy and from Belgium to England witth the use of DMAIC methodology.

This diploma thesis has been created based on the demand of the management of DHL Exel Supply Chain and Swindon Pressings Limited to increase the efficiency and utilization of resources employed within they operations. The theoretical introduction part is first of dealing with the terms "logistics" and "supply chain management" in the perspective of their use in the contemporary logistics theory, comparison of their meaning (are there differences) and explanation of their use in this thesis. Subsequently I am explaining "reverse logistic" and its position in the structures of corporations and logistics itself. Supply chain management and the concept of lean manufacturing combined with the six sigma approach are, from my point of view, essential for today's supplier-customer relationships. That is why those topics are examined in the last part of the theoretical chapter. Returnable packaging and the transport process are key elements of the second part -- practical part, the reengineering of logistics processes which occurred at Swindon Pressings Limited. The aim of this thesis is to analyze the give problem, develop problem solving options and critically comment them. Finally choose one of the options, implement it and document the process of "going live".

Object of this thesis is to give elaborated view of ways and methods for officiating of the efficiency of quality management systems. This thesis is describing and evaluating the current state of quality management systems in chosen firm. In this firm are further applied chosen indicators of the efficiency of quality management. On the basis of quantification of quality management systems efficiency are exposed main problems in quality management in selected firm. This thesis contains proposed correctional remedies for chosen problems elimination. On the basis of repeated measures is further efficiency assessed for realized remedies and is discovered current efficiency of quality management systems in chosen firm.

This thesis is focused on the proposal form filling error rate in life insurance. The theoretical part of the thesis describes main aspects of the methodology Lean Six Sigma, which will be used to decrease high error rate. Lean Six Sigma is widely used in today's companies to improve business processes by increasing their sigma. The methodology is an integration of two separate approaches, both invented in the beginning of the 20th century. The aim of the integration is to bring together the best of both of them. The practical part of the thesis shows how the seemingly separed approaches Lean and Six Sigma can work together. Lean was used to improve the process for insurance company's sales force, and Six Sigma was then applied to decrease the error rate of the forms. Both of the improvements were successfully implemented in the company and led to a desired outcome.

Lean Six Sigma is one of the tools organizations use to help their processes run faster and thus maximize their profits. It is a thorough approach that can reveal defects in companies' processes through examining customers' needs and its statistical data Its popularity spreads fast from the early adopters such as General Electric, Toyota or Motorola and many companies are keen to get their hands on it and achieve similar success as above mentioned. Czech companies are not different. There is, however, a tendency to lay it aside based on first time impressions. The most frequent reasons are: complexity, need to make dramatic changes in the company's culture and high initial costs. Main goal of this thesis is to show that Lean Six Sigma does not necessarily have to be a thorough approach. It can also be used as a one-time tool to improve company's processes, just by picking the right parts and combining them in the right order. This thesis describes the most useful tools and also shows how they can be used in the real situation. By aligning them in a row it also creates a framework for Lean Six Sigma implementation projects which can be used repeatedly. One chapter also describes various problems that might occur during the implementation and provides readers with possible solutions to overcome them.

The thesis, entitled "Six Sigma and improvement of the specific financial control" deals with the Six Sigma methodology in general in theoretical part. It defines the method, the objectives of its establishment, its history, next, theoretical part covers key aspects of Six Sigma, its principles and benefits, tools, management responsibilities for Six Sigma, the COQ in terms of Six Sigma philosophy and most important, the DMAIC methodology, which combines theoretical and empirical part of the project. Practical part illustrates the use of Six Sigma, mainly the process of DMAICR method for ongoing project of the accounting department of financial headquarter of no - named international company operating in Slovakia, which aims to improve the reconciliation process of the Hypotax account as the reason of identifying the weaknesses and significant deficiencies in the process.

The thesis deals with approaches to improving processes and with application of one to a selected production process. Currently, streamlining processes is of interest to many companies, not only manufacturing ones. The relevance of the topic is also evidenced by the number of publications devoted to this very issue. The aim of the thesis is to propose improvements in manufacturing processes in the welding shop through Jiskuhen activities used in Toyota Peugeot Citroën Automobile Czech s.r.o. The first part of the thesis defines terms related to processes and their management, followed by description of some of the widely used improvement approaches and their basic assumptions. The other part of the thesis focuses on the description of Jishuken activities and their subsequent practical application within the company. The thesis offers concrete proposals for improving processes and also recommendations for the management of these activities. This thesis demonstrates the philosophy of continuous improvement in the company, which serves as a reference point for other companies in the area of streamlining of processes.

After events like the global financial crisis and the advent of globalisation, companies have experienced increased competition and pressure to improve performance in the new environments in which business is conducted. This has impacted the world of manufacturing, among others, and has necessitated companies in this industry to adopt improvement methodologies to assist in growing the business. This study looks into the implementation of Lean Six Sigma (LSS) as one of these procedures and highlights that most articles and studies on this process concentrate on the highvolume, low-mix manufacturing environment. On account of this, a gap is left in the application of these techniques in the low-volume, high-mix environment. The literature highlights the differences in the two disciplines that have now evolved into one toolkit that is applied as LSS and how that is achieved. The cases highlighted do not, however, cover the low-volume, high-variety manufacturers, and this paper seeks to use the expertise of LSS practitioners in this environment to get information and derive a framework for successful implementation of LSS in the capital equipment environment. The main contributor to the study is a company that manufactures capital equipment for the mines, with other respondents being practitioners in similar companies and customers in the mines. Respondents were sent a survey to get their opinion on the implementation of LSS in their environment. The survey attempted to gather information through five key questions on how LSS was being applied and its impact on the cost, cycle-time and on-time delivery of the organisation. A quantitative study design was adopted to develop a framework for the successful implementation of LSS in the capital equipment industry. A total of 38 respondents gave feedback, which was analysed, and this showed what - according to the professionals involved in this study - are the vital aspects of this implementation to ensure success. / Dissertation (MBA)--University of Pretoria, 2014. / zkgibs2015 / Gordon Institute of Business Science (GIBS) / Unrestricted
