Now we know there's more than just "QC failures", at least sometimes. We're both using more expansive (and conventional) terms to describe the quality process.
And yes, I still think Demming is in play here. The attitude that 'QC needs to fix this' is exactly what got Detroit in trouble. Demming has everything to do with these things, including stuff like Medical issues that have nothing to do with cars. You need to understand the faiure before you assign blame.....
One of us 'knows' this is a simple failure, one of us (based on experience) knows no failure is simple until understood. One of us thinks the failure is "pretty obvious", the other trained to not make assumptions.
One of us knows that design goes past making a copy of a successful design, and that the details of designs are not always obvious (the basis of many 'trade secrets'). Materials and processing are a part of design, same as the size, shape and color of parts. The parts could very well be made to exactly the specifications called for, but there is no guarantee that those specifications were correct for the job. That calls for an entirely different 'fix' that just beating up your vendors or inspectors.
I also know that assembly techniques can cause issues other than out and out failures. This is the basis for DMIs (Detalied Manufacturing Instructions), being sure it's built the way it's intended (the way engineering built it). I have confidence that QA efforts at Crosman will out, they seem to be doing things right. I also know enough about how this stuff works to not make blanket statements on the importance of QC efforts (Inspection) until more is known. It would seem, at least at one point, one of us knew what the failure mode and solution was, one of us knew he didn't know.
I simply suggested several failure modes that were not the result of inspections or part defects. Things that 'better QC' would not fix. I stick by those examples and can no doubt propose a few more, but that's not the point really.
For the record, I never claimed to know what's up, only that it might not be as simple as better inspection....... Still do, in fact. I think the best call is to give folks time to do their jobs.
