This chapter introduces virtual Organisations (VOs) as a special organisational form of collaborative networks of SMEs to conduct E-Business projects. VOs are normally not created from scratch, but instantiated from a strategic network or pool of enterprises. This enhances the preparedness of participating members when an E-Business opportunity occurs. The underlying strategic network acts as a breeding environment for the VOs. Therefore, it is called a VO Breeding Environment (VBE). Examples from the automotive industry are illustrating the development and needs of this concept. Strategic planning is important for such a network in order to increase chances of occurring business opportunities. The remainder of this chapter shows how scenario-oriented methods such as cross-impact analysis can be used to support a collaborative strategic planning in such networked organisations. The application of such methods allows long-term foresight and the anticipation of the right technological, financial and business oriented decisions.
