Critical Path: Obsolete

This website was recommended by a colleague. I was struck by the presentation and the concept. It made me think back on some of the previous schedules that I have created. Although I don’t claim to be an expert in resource loaded network development (RLN), I can recall seeing on many occasions more than one critical path in my network. This means that there were paths that were identified by the scheduling software as critical and red, but not the longest. Sometimes, the path would begin at the beginning and end halfway. Another path would begin in the middle and go to the end. I would spend a lot of time trying to find the critical path, only to repeat it the next reporting period.
I am interested in hearing some academic/professional feedback on this topic.
You can find the following information on The International Center for Scheduling, Inc.’s website.
“Is the Critical Path Obsolete?”

Is? “Critical Path” Obsolete?
Murray Woolf, founder of ICS, was the 2nd speaker chosen from six speakers around the world. He asked the thought-provoking question: Has “Critical Path” become obsolete? He claims it has, and even calls for the retirement of the term critical-path. His paper was distributed via Internet to a worldwide audience on the 30th of July 2008.
