D6 is Redundant and Add Judgement at D5

If review the chart, we find this may change as,
If verify the corrective action at D5, then D7, else identify possible soluton(red box).

Verification versus Validation in 8D Problem Solving

You must realize the difference between verification and validation:
Roughly speaking VERIFICATION means that you will try whether an intended corrective action works and VALIDATION means that you will confirm that it really works long term.
Verification of a corrective action should be done before or during its implementation. Obviously you will not implement an unworkable corrective action.
Validation of a corrective action should be done after the implementation of the corrective action to confirm its effectivity (that it really works) long term.

D5 and D7 are very different

D5 and D7 are very different. D5 happens before the solution is implemented; it is the work done to ensure the solution will be effective and permanent. D6 is when we implement it. D7 is sharing lessons learned to prevent reoccurrence everywhere it may apply. Operative words permanent then pervasive to ubiquitous.
