Are there any name-brand companies (or even largely unknown but reasonably successful companies) that have managers as described in this blog? Does this tend to be a big consulting problem vs "pure software" companies? I can certainly see this being the case someplace like Booz or Deloitte, based on anecdotes from friends that work at those companies. I've been with the same employer for ~20 years, so obviously a limited experience, but I'd guess 80% of our SDMs were developers themselves and the remaining 20% had complementary roles within dev teams. I've yet to find a manager who was "just an MBA" with little experience as a development team member. Maybe I just lucked into one of the good companies?
