Aim of this thesis is to show practical usage of Six Sigma tools. Six sigma is considered a system of quality control, managerial style or methodology. It is always supported by solid data as it originates in statistics.. Concept is used for improvement of current processes, design of new ones or their better management with one ultimate goal -- refinement of business results. Core of its success is a customer oriented focus and expectation fulfilment. Six Sigma tools can be employed across all business actvities from manufacture to administration. Practical part describes employment of Six sigma tools in four separate chapters. Tools were applied on a real existing company. I am focused on Voice of Customer in the first chapter, which is essential for all other activities across company. Its strong feature is customer feedback. Next chapter deals with 5S tools and their implementation in manufacturing plants and their benefits for company. Third and last chapter describe two projects, which were implemented to back office. Refinement processes were based on DMAIC procedure. Their goal was to accelerate pricing process and sublime output, which is critical for management decision.

Tato diplomová práce pojednává o využití koncepce Six Sigma ve finanční instituci. Konkrétně bylo sledováno využití Six Sigmy na oddělení Správy pohledávek a na Zákazanické lince. V obou případech byly nastavovány procesy příchozích hovorů na tato oddělení. Procesy byly nastavovány pomocí metody DMAIC. Z práce jsou zřejmá zlepšení po implementaci změn. Součástí diplomové práce jsou detailní analýzy příchozích hovorů a defektů při jejich přijímání.

Gábová P. Application of Six Sigma method in repair process. Master Thesis. Brno: Mendel University, 2019. Thesis describes application of Six Sigma method including DMAIC cycle in Zebra Technologies CZ s.r.o. Goal is to decrease number of defect products bouncing back into repair center along with material cost optimization. Prologue describes Six sigma principles and each individual step of DMAIC cycle. Next phase defines objective and scope, process mapping is part of Measure section. Further data analysis gives a definition to defect root cause. Project outcome are precautions proposals that lead to process quality improvement and cost optimization.

This Master's thesis is focused on complaint handling process in the chosen enterprise. The main goal of this thesis is optimization of the chosen customers' complaints using the appropriate Six Sigma methods. In the theoretical part the reverse logistics and its importance are described then Lean enterprise concepts and methods, which are used for the complaint handling process optimization, are explained. The first part of the practical part introduces the enterprise and its logistics and complaint handling process. The rest of the thesis contains the complaint handling process optimization using the DMAIC method.

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 goal of the thesis is the optimization of non-compliant processes and the design of effective workflow for centralization of processing vendor master data at PPG Industries. The idea of unique process leads to savings and also to standardization and thus fulfills legal requirements. In the first part the project deals with the identification of processes, defines central model and process maps used to draft a more efficient process. Proposing part uses the findings to the previous chapters and focuses on implementation to workflow using Six Sigma DMAIC methodology. Final output is the definition of efficient workflow and metrics demonstrating a clear benefit in using these procedures at PPG Industries.

The aim of this diploma thesis is to apply Lean Six Sigma methodology on a specific improvement project in manufacturing company Lindab, s.r.o. The purpose of the project is to reduce number of complaints from inner customer, improve quality of selected product and increase overall effectiveness of manufacturing process. The first part of the thesis focuses on theoretical basis of Lean Six Sigma methodology. Each chapter in this part corresponds to one phase of DMAIC improvement cycle. Theoretical part contains descriptions of methods, tools and techniques used in practical part. The second part is dedicated to practical usage of the methodology. The DMAIC cycle is there applied on project of reducing defects on selected product. Attention is put on detailed process mapping, developing measuring system and process analysis. The main output of the practical part is introduction of specific proposals for improvement leading to reduction of defects and waste in manufacturing process.

The subject of master’s thesis "The study of the operating production management” is to rationalize production and distribution of compressed air. The thesis deals with the description of the current state, the analysis of compressed air production and the proposal for rationalization. The basis of this work is to implement lean manufacturing method in the company DI Industrial. The proposed steps are primarily designed for implementation in this firm but their principles and methods could be used in any company that uses compressed air technology. The study includes theoretical knowledge in the range of Lean manufacturing, Six Sigma tools and a pneumatics.

This thesis analyzes the current situation in company Očenášek. On the basis of the process maps, chronometrical results and computer simulations is compiled value stream mapping current status, which highlights the trouble spots of the process. The proposed solution is drawn up a new value stream mapping, which serves as the basis for evaluation of the proposed solution.

The master’s thesis describes and analyzes the current reservation system of testing devices in Honeywell, spol. s r.o. – HTS CZ, o.z. divize ACS. The system is analyzed by using Six Sigma methods and proposes for improving the current system are prepared. These improvements should improve the functionality of the reservation system and possible savings. Appropriate metrics for measuring and evaluating the functionality of the system are designed.
