This master's thesis deals with modeling of processes of the selected framework for complex management of business informatics using ARIS Designer tool. The reader is introduced into problematics of process approach to business management and process modeling. The next part of this master's thesis introduces some notations and approaches to process modeling and then closer describes the ARIS methodics and tools. The next part of this document focuses on a few frameworks for business IT management and closer describes the ITIL framework and its processes. The second half of this master's thesis describes creation of the model of ITIL framework processes.

The thesis covers the issue of IS audit in all its breadth. On the basis that this is a very complex area, it was necessary to divide the work into several logical and subsequent chapters. Quality and audit are the key words for this job. Therefore is them given the whole first chapter that chronologically describes the evolution of these concepts. Interpretation of quality is widely described since the Greece and Rome ancient, through Total Quality Management approach to the current understanding of the normative frameworks issued by ISO. There is the term audit continuously followed in the chapter of the concept of quality, whose development is also described in detail in chronological order starting from the reading public accounts to the current form of IS audit. Especially, we focus on development of the definition of audit and the relationship between the financial audits and IS. The second - last - part of the chapter is devoted to a detailed description of the reasons for the application of IS audit in practice. Because of the large specifications of the IS audit is this characteristic position in practice given the second chapter. This chapter contains not only description of the characteristics but also a brief outline of the issue of outsourcing and CloudComputing in relation to the audit of IS. The third chapter is devoted to a normative base of IS audit. Due to a large number of normative frameworks there are analysed only selected representatives in the chapter. These include the ISO / IEC 20000, COBIT, ITIL and others. They are thoroughly described, evaluated and compared to other possibly relevant for the definition of relations and benefit evaluation. The last chapter deals with design process of IS audit at a conceptual level. The aim is to freely continue on the normative base discussed in the previous chapter and a simple, versatile, easily applicable and adaptable IS audit process regarding defined limits.

The thesis focuses on research of IT process weakness. In theoretical part are described basic terms and also frameworks or best practise of process maturity rating. Selected practice ITIL and COBIT are then used for rating in practical part. For this purpose is choosen one of process which is outsourced by external contractor. Rating is made using free accessible tools, which are offered by selected practice and which offer rating process. Result is established according to consultation with people involved in project and their rating using mentioned tools.

The aim of this thesis is to map how the most common process-oriented methodologies and standards govern the issue of process ownership, define the role of a process owner and a comparison of these with a current practice in the corporate environment. The first part describes the theoretical concepts related to process management, including a description of selected methodologies. The following part is a questionnaire and its description followed by the expected responses based on previous theories. The last, third, part of the thesis contains an analysis based on the data obtained from the questionnaire respondents compared with the stated hypotheses and its evaluation.
