Primarly it is external enviroment which from menagement requires quick adaptation in new situations or bringing the best buisness decisions in given sircumstances.If it is an unpredictable circumstance, management can only bring the best possible decision in such circumstances. The general or social environment is usually encountered in economic terminology under the abbreviation of the PESTLE analysis, which contains an political, economic, socio-cultural, technological, legal, ecological dimension. It is a large number of factors that require theoretical knowledge, day-to-day monitoring of political events, analysis, official statistical data and the other. But evaluation only in relation to one factor is insufficient, but should be considered with due regard to other factors as each of them directly or indirectly can influence the best possible decision for the company. Therefore, in this work I gave a description of the external environment and after that a detailed review of the general environment or any particular "PESTLE" factor. The work also covers the process of business decision making which includes: deciding factors, developing factors, stages in the decision-making process, identification of problems, defining tasks, recording and analysis of the current situation, and seeking and evaluating a solution to the problem solution. The work ends with the presentation of the practical part of the work, analysis of the company Viro Zagreb d.o.o., that is, how the general environment affects the company and the decision-making process.
