8.3.1/8.3.2ISO 9001:2015 (IATF applies — see related)

Design & development — general & planning

Plain-language summary

If you design products (or under IATF, processes), do it as a managed project: defined stages, reviews, verification and validation activities, clear responsibilities, the right people, and records throughout.

What the clause is really asking

Establish a D&D process and plan each project: nature/duration/complexity, stages and reviews needed, verification and validation, responsibilities, internal/external resources, interfaces, customer involvement, documentation needed.

What auditors look for

Auditors pick a project and check the plan against execution: milestones, review records, who owned what, customer involvement evidence. Where design is excluded from scope, they verify the exclusion is genuine — process design under IATF can never be excluded.

Typical evidence

D&D project plans; stage gates; review minutes; responsibility matrices.

How to comply — recommendations

A simple stage-gate template (concept-design-verify-validate-launch) with a review record at each gate covers planning for an SME. Keep customer touchpoints visible in the plan.

Common nonconformities

Projects run informally with no plan; gates skipped under deadline pressure with no recorded decision; responsibilities assumed, not assigned.
