Hello to all:
First post on the forum so here goes....
This post is an intersection of aviation, document change, configuration control, FMEA, design, and possibly others but I am posting here.
I am working for a small aviation/aerospace job shop as a QE. Anyway, there is a large number of ECO's that are generated as a % of units sold/jobs/revenue etc and is a source of internal failure costs as well as turnbacks, time lost etc and I am in the process of reviewing the whole ECO process. In addition to tuning up the whole "document change" and configuration control processes, I am looking to incorporate some more objective criteria for ECO's to facilitate approvals and minimize risk.
The firm technically does not have "design authority" on many jobs but does own a number of drawings on lower level assemblies and has some lattitude on "changes." Most of these changes are triggered by obsolete parts from suppliers, some for cost savings, and other minor reasons. Of course we are starting to track the cost of quality for some of these changes but I am interested in "front loading" the change process with some more specific justification/criteria for analyzing changes...sort of a mini FMEA approach embedded within the ECO process. I am not interested in handcuffing Engineering so much as I would like to be a little more thorough on evaluating the risks and justifications and alternatives. Some of the criteria would include:
Where else used
Mil or other specifications
Supplier test data,
Most of the "questions" raised during these changes would go away if initiators would be a little more thorough on the front end. I will avoid internal political discussions but I simply want to take some of the guess work out of the approval process and be more thorough.
In the age of global cost competiveness, cheap imports, etc...the risks of quality lapses are very real despite ISO and other certifications. I do not want layers of paperwork but want to be more clear on what is allowed in the ECO process. Any suggestions on what the perfect ECO checklist for risk management would look like?
Again, I have a very good form already that calls out reasons, descriptions, class of change and so on. But what I see lacking is more detail on risk mitigation - objective evidence for justification on that gray area between really minor and major changes that would normally trigger a more thorough review. I am simply trolling for additional thoughts and ideas on the subject.
Thx,
DW
