How do you even define and measure "productivity" in software development? My customers define productivity as "Delivered according to spec on time and within budget." That's the only measurement they care about. As hard as it is for programmers to understand beautiful "clean" code and automated tests are generally not stakeholder priorities. Yes, bad code and no testing has a cost that may have to get paid down the road. I think stakeholders understand that software will fall short of perfection. For a long time the standard practice was unit testing, integration testing, and (if you were lucky) rigorous QA. Plenty of usable software got written that way. There's nothing inherently wrong with TDD and automated testing, and when done right those techniques can reduce the need for more complex testing (integration and QA) and help the team understand what the code is supposed to do. That's not the only way to write good code that works, but it's one way. The problems of defining, measuring, and improving programmer productivity have been known and discussed since the 1960s. We have a set of fairly vague best practices (also known since the 60s/70s) but there's no silver bullet. The problems with developing non-trivial software in team environments mainly come from communication and team dynamics, not from lack of style guides or automated tests. Every little bit can help, of course, but let's not kid ourselves that TDD and automated testing are magic fairy dust.
