Now, I would like to make some comments about your topic "The Radsafe response SHOULD be: What went wrong? What's the root cause? What's the most appropriate corrective action?" In this also I agree with your point of view, however going a little further, I would like to add more questions in your topic, restricted only to what, as you wrote, but also to include why and how. In fact the attention should be to the 7 basic questions: 1) What are the pending safety performance or
safety culture problems?
2) How important? (Significance to safety, reliability, etc) 3) Why did it happen? (fail) (Direct causes) 4) Why were they not prevented? (Root causes) 5) How to eliminate the safety performance or safety culture problems? (Repairs) 6) How to prevent their recurrence? (Remedies) 7) What corrective actions should be implemented (Action Plan) Jose Julio Rozental hits the nail on the head with
this one. One of the issues deserves more discussion, however, and that is
the importance of the subject. We discuss this all the time by pointing
out the differences in the various arguements that are ongoing. What we
rarely do is dwell on the importance or relative importance of the specific
aspect being discussed. We should.
I have an engineering plan for preparing a simple
Important-Performance sheet that assigns importance and performance to competing
values for making decisions. (Values must be independent.) It makes
decision making much simpler if one must allocate relative importance to a
number of values associatied with a project or problem.
Until we look at these competing values, we cannot
effectively make decisions. Of course there may be an infinite number of
values, but many can be lumped into catergories and given importance relative to
the others. Try this by attempting to allocate 1000 points between 10 or
20 independent arguements to assign importance, then give each a relative cost,
do the cross product sum to determine which is the better decision.
Sorry to be vague, but the process should work for
safety issues or dosimetry or air sampling strategies or waste transportation
and give the best choice.
