9.1.2ISO 9001:2015

Customer satisfaction

Plain-language summary

Track how customers actually perceive you — not how you hope they do — using defined methods, and act on what the perception data says.

What the clause is really asking

Monitor customers' perceptions of the degree to which their needs and expectations have been fulfilled; determine the methods for obtaining, monitoring and reviewing this information (surveys, scorecards, complaints, market share, compliments, warranty claims).

What auditors look for

Auditors ask for your defined methods and the latest data, then the action trail: perception dropped — what happened next? Relying on 'no complaints = happy' gets challenged; silence is not satisfaction.

Typical evidence

Customer scorecards; survey results; complaint trends; review records with actions.

How to comply — recommendations

For most SMEs the customer's own scorecard plus a structured annual review call per key account is the honest method. Track the trend, minute the actions — perception data without response is decoration.

Common nonconformities

No defined method beyond waiting for complaints; scorecard data downloaded but never reviewed; declining trends with no action.
