How MassMutual and Mass General Brigham turned AI pilot sprawl into production results

MassMutual and Mass General Brigham shifted from ungoverned pilots to disciplined AI practices to reach production.

MassMutual reported measurable outcomes including 30% developer productivity gains and large reductions in help desk and customer call times.

MassMutual enforces hypothesis-driven development, defined success metrics, and a heterogeneous tech stack with common service layers.

Mass General Brigham shut down ungoverned pilots, deployed Microsoft Copilot, created a controlled landing zone, and enforced clinician sign-off for clinical AI.

Both organizations implemented observability, safety controls, and governance to manage model drift and access.
