Then the Six Sigma gurus and/or managers should be fired. Plain and simple. Accidents happen in finished products only because they are allowed to happen. It doesn't matter if it's the designers fault or the guy who does pack-to-ship.yerasimos wrote:Skiprr, think of it this way: a manufacturer could have two-three dozen whiz-bang engineers and technicians using CAD/CAM and CNC machining, with a dozen six-sigma black belt managers running the show. It only takes two distracted guys--one talking on a cell phone while handling his car keys near some unprotected guns, the other rushing to box them before his shift ends--to send the guns to the distributor/dealer with scratches. Accidents happen in industry, and here the casualty is quality.
I'd be more apt to suspect the two distracted guys accidentally scratching the gun with a handful of keys was downstream, probably at the dealer. The dealer is a retailer, often a small business under a few million dollars in revenue, without the benefit of business process management frameworks used by large companies. My local dealer, whom I love and support with my purchases, takes his ARs and AKs off the wall at the end of each business day--to prevent easy visibility for theft--and puts them back at the beginning of each business day. Were I to examine a damaged AR in his shop, it's that repetitive, unstructured activity I'd suspect over manufacturer error.
Accidents happen in the supply chain, but they should seldom--very, very seldom--happen in production. To achieve Six Sigma, a process must not produce more than 3.4 defects per million opportunities. I'm not saying all firearm manufacturers achieve Six Sigma, but in your example I'll stand by my statement that those managers need to be fired if some process so simple as pack-to-ship causes such an easy opportunity for damage. The company I work for is a Fortune 500, and I can attest that any defect up or down the production line is treated with equal importance.
