Streamlining Production Processes in the TCPA Welding Shop
Vejvodová, Veronika ; Martínez, Felipe (advisor) ; Pivodová, Pavlína (referee)
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.

System dynamics of the quality management projects
Ambrož, Ondřej ; Mildeová, Stanislava (advisor) ; Luc, Ladislav (referee)
Diploma thesis looks into the application of system dynamics and system thinking principles into the projects of quality management. This application offers the new perspective of project of quality management, which uncovers concealed relationships among entities of the system. The principles are specifically applied on the DMAIC cycle of the Six Sigma methodology. The goal of this thesis is to reveal the relationships between the key entities of the cycle, the revelation of the system archetypes with the negative impact on project management triangle and to propose recommendations to eliminate or minimize the negative impact. The goals of the thesis are fulfilled with the methods of analysis of the theoretical ground and its synthesis based on mutual characteristics across the examined areas of System dynamics, Project dynamics, Project management and Quality management. In the practical application the used methods are generalization, deduction, analysis and synthesis of the new systemic and dynamical perspective of the DMAIC cycle. The technical tool used in this process is Causal Loops Diagram. The research has proven the presence of free kinds of system archetypes in the DMAIC cycle, for which are suggested recommendations to eliminate the negative impact on the key indicators. The main contribution of the thesis is the systemic and dynamic approach of the quality management projects, which reveals nonlinear relationships and potentially harmful behavior, which would remain undiscovered under the linear perspective of the system relationships.

Utilization of Six Sigma and Lean approaches within the project management of SAP
Dohnalová, Petra ; Hykš, Ondřej (advisor) ; Čermáková, Kateřina (referee)
This thesis deals with the Six Sigma and LEAN project management methodology and its mutual linkage to Lean Six Sigma. In the first part it describes its basic theoretical principles explaining the background and the roots of both approaches. Furthermore, the adaptation to SAP Sigma is brought to light. In the practical part a case study of the application of Six Sigma on a project called FastClose is introduced and investigated. In addition, Lean Six Sigma methods are applied as well in order to explore further improvement potential within the project.

Project methodology in mobile operator environment
Chvátal, Martin ; Svatá, Vlasta (advisor) ; Svítil, Petr (referee)
Goal of the thesis is a detail description of the project methodology within the Telecommunication Company and pointing out the differences between current existing methodology and methodology standards. The thesis is not just simple description of the project methodology but addition to that it tries to (in given time & material framework) design new solutions for the project process optimalization. The aim of the proposed solutions is to increase competitiveness of the company on the market in current dynamic environment. Thesis has two main parts, theoretical and practical one. Theoretic part deals with general project methodologies and compares theirs main features and characteristics. One of the chapters is also describing Six Sigma process methodology, that will play a major role in the practical part of the thesis. In practical part, first of all I am introducing the company Vodafone Czech republic which allowed me the creation of the diploma thesis. Following chapter is focused on existing project methodology, project life-cycle and tools that the company uses in day-to-day practice. Next chapter deals with the detail analysis of the project process and by using of real samples of the company projects I try to find the optimalization of the project process in order to speed up the time to market and thus provide faster reaction to the market conditions and needs. Final chapter provides a summary and conclusion of the work done. Benefits of the diploma thesis should be following: 1)Detail mapping of the project methodology in mobile operator environment 2)Analysis of the current existing project process and project lifecycle 3)Possibility to get greater knowledge about the work of the Project management office 4)Design a possible solution that would help to increase competitiveness on the market

Utilization of Six Sigma tools in practice
Prepletaná, Miroslava ; Hykš, Ondřej (advisor) ; Vargas, Gita (referee)
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.

The Six Sigma methodology
Zajícová, Hana ; Jarošová, Eva (advisor) ; Malá, Ivana (referee)
Bachelor thesis deals with the desription of the statistical foundations and individual steps of Six Sigma, which are descibed by the DMAIC model. The thesis focuses on statistical process control and control charts. The main goal is to evaluate the possible use of control charts for attributes, namely the control chart for fraction nonconforming or p-diagram and to describe its properties expressed by the operating characteristic (OC). The influence of the sample size on the OC curve is examined. The last part of this theses deals with the desription of the xi-diagram as an alternative of the p-diagram. The properties of this alternative and classical p-diagram are compared.

Six Sigma and improvement of the specific financial control
Otčenášová, Jana ; Pelák, Jiří (advisor) ; Zouhar, Tomáš (referee)
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.
