o provide new innovative services and business models in order to be able to maintain or increase their revenue per user. On the other hand, some new services and business models might be introduced by completely new kind of CPS's, which do not yet exist on the market. This statement is seen as very likely, which may indicate that the CSP's business environment is not seen as a stagnating one, but rather as a renewing and turbulent one. 2 Low Likelihood - High Impact This set of miniscenarios was rated as having a low likelihood but a high impact. They can thus be considered as critical for the actors' future business: They are not seen currently as a threat, but if they were to realize, they would most probably completely reshape or ruin the OSS/BSS software vendors' business. MS4: A pluggable service-supporting architecture with standard interfaces will be provided in a form of a single software package. SDP (see chapters on "Industry Structure Evolution" and "Vertical Integration due to Software Systems' Modularity") is not expected to emerge in a single L. Frank product like form; instead there are likely to be various alternatives about how to organize the delivery of services. If, however, a single product would emerge, it is seen to have a high impact on the markets. This could mean that the experts see a demand for this kind of software. The demand seems to be hard to satisfy, as CSPs' existing software systems vary much, and it is hard to provide a single software which would easily fit and plug into every or most CSPs' operations. MS7: IT service providers (such as, e.g., Accenture) will dominate the OSS/BSS market with customized offering, based on NGOSS specifications. An invasion by large software vendors into the OSS/BSS markets has already started. Currently, however, these large software companies have not yet succeeded in diminishing the position of OSS/BSS specific vendors - and the experts do not see that as a likely evolution within the next 5 years. However, were they able to conquer the mark
