Business analysis is a useful tool primarily used by management in planning, and as such is the basis for making strategic and operational decisions in the organization. It is applicable to various types of organizations with certain specificities depending on the sector, and this thesis will analyse Privredna banka Zagreb d.d., one of the largest commercial banks on the Croatian market. The internal and external environment of the company will be analysed with an emphasis on SWOT and PESTLE analysis as well as industry analysis using Porter's five forces model. Also, an analysis of the financial situation will be carried out, so this thesis will combine both aspects with the purpose of better assessing the business performance of the observed company. Banks in Croatia are credit institutions licensed by the Croatian National Bank, and their role in the economy is indispensable. The main goal of the thesis is to draw a conclusion about the success of the operations of Privredna banka Zagreb d.d. based on the conducted analysis. With the method of description, analysis, synthesis, induction, compilation and comparison, the stated goals will be achieved and the obtained information will be able to be used by the general public.

The scientific contribution of the thesis is reflected in the development of scientific thought about the concept of business analysis and the presentation of models and instruments for its implementation.
