Many people have the dream of creating their own business and being independ-ent from others. Indeed, being self-employed provides the possibility of being completely flexible and able to control all business decisions. However, empirical studies reveal that being self-employed can be a big challenge too and that many people tend to overestimate their own skills. As a result, many self-employed persons fail and have to shut down their company. Thus, this master thesis deals with the critical success factors of the founding pro-cess of self-employed persons in the area of project management in Austria. In general, three different groups of critical success factors can be distinguished: in-dividual-related, enterprise-related and environment-related critical success fac-tors. The results of the empirical research have revealed that individual-related critical success factors are most important concerning the founding process. In total, 19 individual-related critical success factors were identified during the research. The most crucial individual-related critical success factors are work and industry expe-rience, business skills, endurance, flexibility, saleability, willingness to take risk and education. The second most important group of critical success factors are the enterprise-related success factors. In this group nine critical success factors were gathered. The most crucial enterprise-related success factors are network, financial plan-ning, corporate strategy, price policy and foundation planning. Eventually, the least important group of critical success factors are the environ-ment-related success factors. For this group, only six critical success factors were identified. The most relevant ones are the corporate culture of the customer, the location and the economic situation.
