Learn at the feet of a master screw-up
Bad project managers that I’ve worked with have taught me more about project management than even the best project managers.
We often have to practice our art for years to make the same kind of gaffs and goofs that a single bad project manager can make in a month.
If we are patient, and pay attention to what they are doing, we get to a ringside seat to their mistakes and valuable lessons in to precisely what not to do.
