Within foresight management in general and scenario development in particular, the question is often asked: "For what scenario do I have to be prepared?" Since there are manifold approaches of scenario technique, the ways to answer this question with the help of scenario technique are also manifold. Scenario approaches using probabilities, for example, would recommend emphasizing the most probabilistic scenario. However, the consideration of probabilities, in our opinion, is not always useful. From a combinatorial point of view, any given scenario has an infinitesimal probability of being right, since there are so many possible variations (Gee et al. in Deep News Glob Bus Netw 2(4):199, 1991). Additionally, when regarding all possible developments that may be relevant for a scenario, each development has only an infinitesimal probability of coming true. Following these thoughts, the consideration of probabilities often has no additional benefit and, therefore, is not necessarily needed within scenario development. In this paper, the use of probabilities in scenarios will be discussed. On the one hand, this includes a discussion about scenarios in which the considerations do not make sense. On the other hand, the paper will also show an approach of considering additional information within the scenario creation process to select the most important scenario.Keywords Scenario process .

PrefaceHaving developed scenarios within foresight management, it is often unclear for what scenario a company has to be prepared. Different existing scenario approaches presumably also deliver different answers in this (decision-making) situation.In this context, Bradfield et al.[2] provide a good overview of the existing schools of scenario technique using several criteria for classification. One classification criterion is the use of probabilities for the development of the scenarios. Probabilities within scenario technique are well discussed in literature -along with their advantages and disadvantages [1,3,4]. We will pick up these discussions and take a deeper look at probabilities in scenario development. We divide our consideration into three parts in order to do this: the use of probabilities within the scenario creation process; the attachment of probabilities to the developed scenarios; and probabilities in the scenario controlling process.Since we see that the disadvantages dominate the advantages of using probabilities, the paper clearly takes a position against the use of probabilities. Hence, the paper constitutes more a position paper than a discussion paper. Nevertheless, it is naturally also our intent to foster discussion about the use of probabilities.
