Overview

Systems Integration covers the design and integration of complex, multi-vendor technology systems — connecting disparate applications, platforms, and infrastructure into working end-to-end solutions. It is led by the global integrators (Accenture, IBM, Infosys, TCS, Deloitte) that handle large-scale enterprise transformations, ERP implementations, and complex integration programs.

Demand is driven by enterprise complexity, digital transformation, cloud migration, and the need to make heterogeneous systems work together, with large integration programs (ERP, cloud, AI) being multi-year, high-value engagements. It is consolidating around scaled global integrators, with the work shifting toward cloud-native, API-driven, and AI-enabled integration; it sits within computer systems design services.
