Add to that the problem that "productive" is not the real goal. Businesses can survive and even thrive with sub-optimal processes as long as those processes deliver value that exceeds their cost. (We see this in early stage startups, i.e. "Do things that don't scale".) Needing a development process to run optimally in order to deliver value suggests that the marginal value may be far too small for a custom software solution.
