Monitoring, measurement, analysis & evaluation — general
Plain-language summary
Decide what to measure, how, when, and when to analyse it — then actually evaluate QMS performance and effectiveness from the data, keeping the evidence.
What the clause is really asking
Determine: what needs monitoring/measuring, the methods (valid results required), when to measure, when to analyse and evaluate. Then evaluate the performance and effectiveness of the QMS and retain records. The clause turns gut-feel management into data-driven management.
What auditors look for
Auditors map your KPI architecture against your processes (4.4): does every process have a measure, does data actually get analysed (not just collected), and do evaluations lead anywhere? Dusty dashboards that nobody acts on fail the intent.
Typical evidence
KPI definitions and data; analysis reports; evaluation records feeding management review.
How to comply — recommendations
One measurement plan: KPI, process, method, frequency, owner, where reviewed. Collect less, act more — five live KPIs beat thirty dead ones.
Common nonconformities
Data collected but never analysed; no defined methods (numbers nobody can reproduce); processes with no measure of effectiveness.
