(2009-2013). The expert group consisted of ten research organization represen- tatives, ten OSS/BSS vendor representatives and ten CSP representatives. Additionally, the experts were given a possibility, by means of open ended questions, to comment on the presented statements. For the evaluation, an internet questionnaire was used. Altogether 11 experts responded to the ques- tionnaire by the set deadline (while that number is modest, it has to be kept in mind that the quality rather than the quantity of experts counts in studies regarding future).

Frank Impact Fig. 1 The evaluated likelihood and impact of the presented miniscenarios 4. The experts then evaluated those 16 statements as regards their likelihood and impact. As a result the following four groups, based on their evaluations' average ratings in relation to the mean values, were formed: a. High likelihood - high impact b. High likelihood - low impact C. Low likelihood - high impact d. Low likelihood - low impact. The final grouping of the 16 miniscenarios is shown in Fig. 1, followed by a discussion of their potential meaning for the future of the OSS/BSS industry. High Likelihood - High Impact These miniscenarios were rated as having a higher impact and likelihood on average. They are thus considered as likely to occur and also as having a significant impact on the OSS/BSS industry. In the following, these scenarios are described and analyzed in an ascending index order: MS8: There will not be enough customers for OSS/BSS software vendors in all the product categories. Simultaneously, the software market will concentrate around software integra- tion of merging telecom service providers rather than new product introductions. It is
