This development leads to the situation that capital investments in the hospitality industry are connected with ever increasing risks.

Getting hold of information and the appropriate usage of this information is crucial in order to ensure the success of a study. The main objective of this diploma thesis is to identify the most important and current issues in feasibility evaluation of hotel projects. In practice, many studies are prepared following a fixed model, which has not been changed for years. However, the hospitality industry is highly competitive and dynamic, new additions to the existing supply therefore need to be analyzed very carefully. The focus of this diploma thesis is specifically put on the hospitality industry. This means that feasibility evaluation for other types of project development in the tourist industry is not subject to this study. The aim of the thesis is on the one hand to point out aspects that have to be taken into consideration in any study, and to give suggestions for improvements on the other hand. The author has laid down the following four hypotheses that serve as the main source for t
