What I am saying is that few product people have the vision of what is needed - and have the right vision of the end result. Most product people more of iterative meandering tourists with vague idea of the end result rather than captains that have exact understanding where they ought to be in a week - as per having a useful and usable progress that moves everyone measurably closer to successful product.
Maybe I ask too much of my product people, but that's the reality - there are only so many steve jobses out there. People like to believe they have the traits but often lack similar "from the early years" experience of being in the whole basics of production to managing part that jobs had.
So to sum it up, too much of Wrong kind of technical debt. Sort of buying a ferrari when you need a house - because your wife will have a child soon ;)
