In what world do PMs actually think the supposed thoughts in this article? Yes, it's important to document well, focus on why not how, and be a shit umbrella not funnel -- though these have been PM 101 everywhere I've worked.

But when PMs infringe on these issues (and yes, all PMs do) I find it's rarely a conscious decision as much an impulsive/instinctive thing from being torn in 100 directions at once.
