Why use an MSP?

Establishing and maintaining an in-house program to manage a large non-employee workforce in addition to finding the expertise to strategically source, benchmark programs, and facilitate continued program maturity can be a significant undertaking. An MSP uses tools, such as a Vendor Management System (VMS), and has the skill sets and experience to manage the entire life cycle of sourcing contingent resources and services, onboarding and offboarding non-employee workers, and managing the invoicing process around the world.

Data is a critical component to any successful program – what data should be captured, how to analyze the data, and how to “read” what the data is saying. MSPs are adept at making sense of data to enable better decision making, support program changes (or not), and guide budgeting and forecasting.
