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.
Market snapshot
Not sized separately. Custom programming and systems design cover this node and every other delivery segment beside it — consulting, implementation, infrastructure services and outsourcing all draw on the same classification, so the figure belongs to the parent. Integration work is nonetheless the stickiest of them: once a firm has wired a client's systems together, it owns the roadmap.
