In the previous post I mentioned Paul Ritchie. Paul works for SAP and is Head Global Project Management. I came to Paul's site through a reference. A quick read put him on the list. But now that I've started reading more of Paul's materials, my view has changed.
I rarely suggest that someone take a deep dive into a topic in the way I'm suggesting you do with Paul's Blog. This is not one of those self serving endorsements. Paul's Blog is a source of professional grade project management advice.
That's all I can say. A new found voice of reason, experience, and practical advice in the sea of confusion, conflict, self serving opinions, and over sold methods.
