Explanation
Carrying out a measure is not the same as solving a problem. With the effectiveness check you look back later: has the problem not returned, does the new way of working work, is the risk lower? That prevents actions from being ticked off without result.
You plan the check in advance, with a date and a way of measuring: counting reports, a sample, an inspection, a short audit or a conversation with the people doing the work. The moment must be far enough after implementation to see an effect. That depends on how often the problem occurred.
If the measure is not effective, you go back: the cause was wrong or the measure was too weak. You start a new analysis and a new measure. Anyone who skips an effectiveness check misses the Check in the PDCA cycle.
Example from practice
After introducing an extra control step against wrong labels, the quality officer counts complaints about labels for three months. If there are no new ones, he closes the action. If there are, a new analysis starts.
