The contractor I am working with advertises as being a CMM Level 5 developer.  My understanding is that is a big deal.  To have such highly repeatable processes that are fully circular evaluating and correcting faults inline.

Then the project lead told us how it really works: based on the project type, size and duration you could be anywhere from a 3 to 5.  For example, a custom product, less than a few years and under 10 people is a 3.

I think it’s odd that everything at a company isn’t level N or M.
