What is it about "Project Management People" that causes them to express themselves in aphorisms? For an example check out this blog. Is there not enough truth that they feel compelled to make up some more? Is it that an aphorism reads well on a powerpoint slide? How can "Project Management" have more aphorisms than a more concrete science like physics?
I'm going to go out on a limb here and postulate: "The more aphorisms, the less knowledge"
