When choosing a VMS technology and MSP service provider don’t jump too fast to base your decision on the providers capabilities in contract labor alone.
Statement of Work (SOW) spend in many organizations dwarfs contract labor spend. The major VMS players lack the knowledge & capabilities to manage SOW spend effectively. They will tell you they do but when I talk to my customers who have tried to use them they tell me the VMS/MSP players are missing the mark.
From a technology perspective few can handle true SOW transactions. These transactions can be complex with detailed and many deliverables/milestones and acceptance criteria. Scope changes further exasperate the traditional VMS/MSP providers.
If you have SOW spend in your organization make sure you add it to your service provider decision criteria with at least 50% weight factor (or more).
