Most companies have a quality system on paper. Fewer have one that actually governs behaviour in everyday work. The difference doesn't lie in the documentation, but in the routines that ensure problems are caught, analysed and solved at the source.
When the system only lives in the folder
A quality system that exists solely as documents is typically updated before an audit and forgotten afterwards. The same complaints keep coming back, because the cause was never removed — only the symptom was handled.
CAPA: corrective and preventive actions
CAPA routines ensure that a deviation isn't simply closed but understood. Corrective actions remove the current fault; preventive actions remove the possibility of it happening again. It is this preventive part that decides whether the problems stop coming back.
Hallmarks of a quality system that works
- •Deviations are recorded the same day they occur — not at the next audit
- •Root cause analysis is carried out systematically, e.g. with 5-why or a fishbone diagram
- •Preventive actions have an owner and a deadline
- •Status is visible to those who work with the process
Visibility creates ownership
When quality data is visible where the work is done, quality becomes part of the daily conversation rather than a control function. That is a precondition for employees to take ownership — and for the improvements to hold without constant follow-up from above.
To structure the root cause analysis itself, you can use our A3 problem-solving template and 5-why template. The hidden costs of faults arising at all are covered in Cost of Quality.
✓Concrete takeaways
- →Solve the cause, not the symptom — otherwise the complaint returns
- →Make quality data visible in operations, not just in management reports
- →Give each preventive action an owner and a deadline
- →Measure whether the same faults fall over time — that is the real test
