(I don't think GE Aerospace is the same GE that makes military jets, are they? Its hard to keep track of the players with all the corporate reshufflings going on. During the Cold War, we'd rather have let the Russians into the plant than let any GE reps into it! :-) I'm sure work was going on with CMM for quite some time before I became aware of it. You may be right about the '89 time frame being when it started to gain some momentum. I guess my point was that we were not developing our Pictures-to-Code process with an eye towards getting CMM certification. It just sort of worked out that what we were doing to make a profit also assisted in getting us the certification. > Last I heard they (now part of LMC) were at level 4, shooting for 5. > LockMart is shooting for a Level 5? What is it that they are making at that particular chunk of LockMart? There has often been debate on the economics of shooting for anything above Level 3. There is some belief that 4 and 5 are interesting and nice work if you can get it, but that money sunk into achieving it does not translate into money returned on the bottom line. Of course, a lot of that depends on the kind of software you are busy building, too. Not all things worth doing are worth doing well. Fortunately for us, our embedded software is similar enough from one project to the next that it lends itself to process improvements more so than other types of work.
