IMS (Integrated Management System)
An integrated management system combines two or more management standards — typically ISO 9001, ISO 27001, and ISO 42001 — into one system that shares policies, audits, document control, and management reviews instead of running parallel structures.
Why integration works
All modern ISO management standards share the Annex SL high-level structure: identical clause numbering, shared concepts like context, interested parties, objectives, document control, internal audit, and management review. Roughly 60–70% of the clauses can be satisfied by one common process — the remaining part is the discipline-specific layer (risk assessment methodology, control annexes, operational requirements).
The benefits compound: one audit cycle instead of three, one document-control system, one management review covering all disciplines, and a single policy hierarchy — which cuts cost and, more importantly, keeps the systems consistent with each other.
How to build one
Start with the most mature existing system as the skeleton, map the other standards’ discipline-specific requirements onto it, and run a gap analysis per standard to catch what the shared layer misses. Our detailed article walks through combining ISO 9001, 27001, and 42001 into a single IMS.
