Abstract

From small service providers to large enterprises a need to collaborate and share expertise and resources, as well as costs and risks on-the-fly exists. This need arises from the challenge to remain competitive in an aggressive global market.

The current technologies are enabling novel and innovative businesses never possible in traditional setting, such as on demand composition of offerings from distinct providers to address a customers needs.
