A while back the LPS was conceived to address the unreliablility in project execution. Without going into all of it in a 'comment' I'll say that dependence and variability (as described by Goldratt) were the breakthrough ideas that led to the current incarnation of the LPS. While there's no arguing that some resources can be contraints on a project, all resources, specifically people who promise, can add to the variability experienced on the project. Attending to the reliability of the promising of all while giving extra attention to the constraining resources has resulted in significant performance improvements on projects. BTW, you'll never catch me arguing with Goldratt. The Theory of Constraints is an incredible contribution to production management, especially one-of-a-kind production, a.k.a. 'projects'.
