Well it is broken, damn it. This whole thing flies in the face of what you and Dr. Ron and I are always talking about, LEAN and continuous improvement. This is the opposite; I don't get it. I mean people are actually maintaining inventory in preparation for building scrap. This is insane. How did we evolve to this? Where did this come from?
Jim I think one of the problems is they don't want to know; they don't want to deal with DPMO, defects per million opportunities, percent first pass yield. They're taking first yield after you do touch-up. All these things contribute. I think it's just hiding a problem. Phil We have something we call the consultant's dilemma. To paraphrase our Car Talk Brothers, but basically we feel like we're mechanics. One of the things we have in common with them. This is what we typically see. People have a defect problem: "Maybe if I ignore it it'll go away," like putting duct tape over the Check Engine light or turning the radio up to hide a sound. Then they go a little further: now it's starting to get a little bit more severe, kind of swerving from side to side, hitting the curb, things like that: "Well, let's try to fix it ourselves," oh, finally getting to do something. Sometimes they succeed; a lot of the times they don't, and it gets worse. And then maybe they'll call in the consultant.
But anyway, it's that first thing, that complacency, where they're living with a certain level of defects. How do we get this way? Is this an indictment of our society and our whole culture? Jim Phil All right, I'll calm down now. Jim And speaking of soldering. Don't solder like my brother. Phil
