What is Effectiveness Verification?

In 30 seconds

Effectiveness verification is proving, against a criterion and period defined in advance, that an implemented corrective action has actually eliminated the problem. Completing the action does not mean it was effective.

How does it work?

  • When the action is chosen, a success criterion and monitoring period are defined (for example, no recurrence of the same defect over a set period).
  • After implementation, data is collected and compared with the criterion.
  • If the criterion is not met, the case returns to root cause analysis.

Often confused with

Implementation check and effectiveness

Confirming that the action was carried out is a check; showing with data that the problem is actually gone is effectiveness verification.

Common mistakes

  • Setting the criterion after the fact.
  • Closing the case before the monitoring period ends.

From a QWorks perspective

In QWorks closure is verification, not a record: a case does not close without effectiveness evidence.
