This document discusses challenges with traditional managed service provider (MSP) models and proposes an alternative approach. Specifically: - Traditional MSP models rely on high candidate availability but face challenges like skills gaps, a candidate-led market, and a busy agency market. - The author argues that a "one size fits all" approach does not work given today's tight labor market conditions. - They propose an "adaptive" model where the MSP is more flexible in terms of the agencies used, account management styles, and pricing structures in order to better meet each client's unique needs over time.
