In our 15-criteria evaluation of digital platform engineering services (DPES) firms, we identified seven vendors making inroads in this emerging business technology services market — EPAM Systems, GlobalLogic, Harman Connected Services, HCL Technologies, Luxoft, Ness Software Engineering Services, and Persistent Systems. Forrester defines digital platforms as the new generation systems — like digital experience and the internet of things (IoT) — that drive customer experience and differentiation. This Forrester Wave evaluation analyzes how each DPES provider measures up, and it helps CTOs and VPs of product development make the right choice based on their unique needs.
