Abstract: This paper evaluates the real options approach (ROA) as a means for appraising capital investments under uncertainty. Globalisation and growing competitiveness have led to an increase in uncertainty with regard to companies' decision making. Flexibility to react to this uncertainty has become more important. The question arises whether there is a need for a further investment appraisal technique or whether traditional techniques can cope with that. A growing literature about real options shows that traditional investment appraisal techniques do not value flexibility. That is why ROA has become more important within recent years. However, the degree of its utilisation by companies seems to be rather low. Three possible reasons for that are examined: ROA is not well-known by companies, especially small- and medium-sized enterprises. ROA is only limitedly applicable. ROA is too difficult to use. After traditional investment appraisal techniques have been outlined, the real options approach is illustrated by means of a case study. The possible range of application is assessed by reviewing the literature. A survey was conducted to check whether companies know about or apply that technique, and to identify the tools used by companies. This study shows that while the range of possible applications of real options is rather vast, ROA is rarely known by German and British companies and barely applied. One reason might be, that most books and articles are of rather academic nature. This seems to have been realised since books with a focus on practical application have been published recently. The complexity of ROA seems to be a further reason for its low degree of utilisation. Companies tend to use simpler but more comprehensible techniques although these methods have some major drawbacks.
