That might be based on a misconception of what the CMM is all about. CMM at any level doesn't guarantee that your software is free of bugs or of high quality. What it guarantees (sort of) is that you have a process for producing that software which is under various levels of control. The old analogy of the concrete life preservers is illustrative here. You can have a CMM Level 5 process for making them, but they are still about as useless as tits on a bull. Our software is safe more because of competent design and intense verification. This can be done even if you are inventing your processes on the fly. So relax as you place your tray in the upright, locked position. Call that stewardess over and ask for a pillow and a double martini (shaken, not stirred) and take comfort as those mighty Pratt & Whitney engines spool up. We make thrust you can trust!
