process of reducing engineering errors & ecn'n 2

[duk748]

hello - our company has recently evaluated our ecn or eco process & found that even w/ the use of 3d cad our shop drawings used to manufacture our equipment still have too many errors - we do no checking leanning on the person who created the drawing to be responsible for his work - has anyone a plan that seems to work well to eliminate the rework, mistakes & ultimate ecn's that come w/ them -
our errors are costing us many $$ - also anyone wish to share a plan or procedure that works to eliminate the number of ecn's in general within their company - any info or feed back would be graetly apprecaited - thank you

Sadly duk, we eliminated the checking role a couple of years back

KENAT did you come to unnecessary checker role due to step down someone or change a philosophy to his role in office?
If for example several groups are developing product for different project I see it is almost impossible to fulfill checker role in office by one person.
Much better if in separate teams lead designer will combine checker role during design develop.
All above of course IMHO

There was no unnecessary checker role. I came to take the necessary checker role because they fired the previous experienced and very good incumbent as part of a 'reduction in force' for the more targeted reasons mentioned above.

I already mentioned that the checker doesn't have to be 100% full time checker if the volume doesn't justify it. However, whoever does it needs the appropriate skills and experience and at least around here the team leads or whatever you want to call them wouldn't have that.

If you're lucky enough to be in an environment where everybody has the experience & skill to be a checker then yeah peer review will probably work fine. However, I don't believe this to be the norm.

You are also right that it can be a struggle routing everything through one person or a small team. However, good project planning and appropriate mitigation's should take care of this.

I want to emphasize that I don't see the checker role as just an end of the line final inspection process. They should also be subject expert that people come and ask questions of preemptively, they should be taking the lead in educating folk, involved in DFMA...

It doesn't matter if there is a full time checker. What does matter is that the checker is competent and diligent.

thread1103-193286 gives some ideas on what would define a 'competent & diligent' checker.
