Continual improvement
Changed in ISO 9001:2026
There is no clause 10.3 in ISO 9001:2026 — continual improvement is folded into 10.1. Keep citing 10.3 until your transition audit, then re-point every reference.
Plain-language summary
Keep making the QMS itself better — suitability, adequacy, effectiveness — using what analysis and management review reveal as needs or opportunities.
What the clause is really asking
Continually improve the suitability, adequacy and effectiveness of the QMS, considering the results of analysis/evaluation (9.1.3) and management review outputs to identify needs or opportunities to address.
What auditors look for
Auditors look for the loop closing: analysis findings and review outputs becoming improvement actions, and the QMS demonstrably better over time (trend direction across years, not just activity).
Typical evidence
Improvement records traceable to analysis/review outputs; multi-year trend evidence; updated processes/documents from improvements.
How to comply — recommendations
Once a year, ask one honest question in management review: 'where did the SYSTEM improve, not just the product?' Document the three best answers with their measures — that is continual improvement, evidenced.
Common nonconformities
Improvement claimed but trends flat for years; actions never traced back to analysis; system improvements indistinguishable from routine corrections.

Chapter 10 — Improvement — Closing Loops for a Living treats this clause family in full: what it is really asking, what auditors look for, the evidence that satisfies, how to make it work on a real floor, and where companies stumble.
