Adding One More Phase Makes it even Harder to Apply

Though 8D is a fairly comprehensive way of solving problems in a systematic way, it has not gained as wide an acceptance as some of the other mantras (formulas) like P-D-C-A, DMAIC etc. In my opinion this could be due to the large number of elements being involved.
The suggested D0 is a one time requirement for the top management and so may be kept out of 8D, which is for CPA (corrective and preventive action)
In fact we could make it a three step Solution process
Step 1. Containment solutions (D1-D3)
Step 2. Root cause solutions (D4)
Step 3. Implementing and verifying (D5-D8)
to make it short to remember and implement.
