Analysis & evaluation
In ISO 9001:2026
Checked — the evaluation list grows from seven items to eight: the effectiveness of actions on risks and on opportunities are now separate evaluations, matching the split in 6.1.
Plain-language summary
Turn your data into decisions: analyse and evaluate to judge conformity, satisfaction, QMS performance, planning effectiveness, risk actions, supplier performance and improvement needs.
What the clause is really asking
Analyse appropriate data from monitoring/measurement to evaluate: product/service conformity, customer satisfaction, QMS performance and effectiveness, whether planning was implemented effectively, effectiveness of risk/opportunity actions, external provider performance, and the need for improvements. Statistical methods among the tools.
What auditors look for
Auditors look for genuine analysis — trends, comparisons, correlations — rather than raw data tables, and for each of the listed evaluation outputs appearing somewhere (typically management review).
Typical evidence
Trend analyses; quality reports; supplier performance evaluations; analysis inputs to management review.
How to comply — recommendations
Build the analysis around the listed questions — one page per question per quarter answers the clause and gives management review real content instead of data dumps.
Common nonconformities
Raw data presented as 'analysis'; no trending across periods; risk action effectiveness never evaluated.
