We published a Forrester Wave on business service management (BSM) in March 2007. It has generated a lot of interest in the topic from both users and vendors, particularly around its finding that there are several different types of BSM project. The implication that there are different buying centers and drivers makes it even more difficult for vendors to apply the right sales approach with every prospect. Participating vendors can always use Forrester Wave research to identify potential improvements in both their marketing and sales processes, but there are also individual "what it means" (WIMs) for each vendor. Vendors not covered in the evaluation can also learn important lessons from the results.
