Since the end of 2008 and continuing today, sourcing and vendor management (SVM) professionals have been telling Forrester that they are rationalizing the number of providers they use, renegotiating contracts with the remaining players, and finding ways to increase value from their preferred providers. These buyer changes aren't going unaddressed by IT services firms, which are changing their offerings and their internal operations to succeed in the face of changing user requirements. SVM professionals need to understand how the services landscape is shifting to ensure that they derive maximum value from their services providers and can take advantage of significant market changes.
