Add D0 to 8D Problem Solving: Create the Appropriate Culture

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) teams.
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.

Extra Initial Step for 8D Problem Solving Not Needed

A separate D0 phase for Culture may not be necessary, because I feel that inculcating such a step wise activity is a pre requisite of a culture change by itself.

Should D0 be Added to 8D?
Fred Newcomer, Consultant, United States, SIG Leader
Several years ago I was researching 8D and discovered the premise of D0.
I learned that it was to determine the efficacy of using an 8D process for a particular problem. So, my thought is to consider D0 as a step to review the problem at hand and determine if it fits operational criteria to be considered for 8D.
Operational criteria could include cost of failure, cost of compliance or lack of compliance, or a loss of customer.
