In the first part of thesis the theoretical segments of company's environment have been explained.

In the practical part of my thesis I analyzed the company “Tankerska plovidba d.d.” from Zadar. “Tankerska plovidba d.d.” is Croatia's leading shipping company, whose primary activity is the transport of oil and oil products. In addition to oil transport, the company is engaged in sea and coastal water transport of passengers and goods and is providing services to maritime transport. The analysis of the general environment of “Tankerska plovidba d.d.” was made by using PESTLE analysis. The business environment is closely connected to the company; therefore, companies are more focused and oriented on enterprise business environment. The business environment consists of suppliers, customers and consumers, competitors, shareholders, employees and trade unions, creditors, government (state) organizations, community organizations and professional associations. Analysis of the business environment of “Tankerska plovidba d.d.” was performed using business environment scanning, competition analysis and analysis of company's stakeholders. For the analysis of the industrial environment Porter's model of five competitive forces has been used. SWOT and TOWS matrix, linking the internal and external factors of the company have been made, in order to reach the best image of the company. Next step after the analysis of the environment is to set organizational direction and to determine the directions of the organization. This includes defining the vision, mission and company’s goals.
