Prioritization (IATF only)
Plain-language summary
Trends and performance data must drive the priority order of improvement actions — worst and most customer-critical first, visibly.
What the clause is really asking
Trends in quality and operational performance get compared with progress toward objectives and lead to action prioritisation — analysis is not complete until it has reordered the action list.
What auditors look for
Auditors look for the connecting evidence: the trend review and the resulting prioritised actions (improvement plans, resource allocations) reflecting the worst trends and customer impact.
Typical evidence
Prioritised improvement/action lists traceable to trend data; management review outputs showing reprioritisation.
How to comply — recommendations
Close every quarterly data review with one output: the re-ranked top-five action list, dated. The re-ranking record is the compliance evidence and the management habit worth having.
Common nonconformities
Analysis and action lists living separate lives; resources spread evenly regardless of trend severity.

In the book
Chapter 9 — Evaluation — Reading Your Own Instruments 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. This IATF requirement is covered in the Automotive Edition, in the same six blocks as the ISO clause around it.
