Considering failure rate of PMI led projects is even higher then agile projects for software. I really wouldn't hold that up that as the way to go.

PMI (critical path) != waterfall. But then that's also said of "agile", which too often devolve to waterfall.

Project management is risk mitigation. In my experience, most "agile" projects have been risk amplifiers. Ironic.
