Linkages are pre-planned connections from one offering that pulls through the next offering. The connections are made by carefully pre-planned and executed sales activities. Of course in reality, linkages do not begin at the end of one project and end at the beginning of the next. Linkages are positioning activities that take place during the initial sales process and during projects. The positioning may not only be related to the next project in the Service Chain, but also can be made with regard to the entire Service Chain.
