Josh, That’s a great answer. You even got to the part I hadn’t asked about yet, which was, what do you do on government projects where you can’t just rebaseline at will.
Your presumption wasn’t far off, but the real monkey wrench is this scenario: What if I generically assign a task to a skillset called “Electrical Engineer” at the onset of the project, but then later change that assignment to Joe and Jim? Joe and Jim won’t have any baseline values unless I rebaseline that task. That’s fine, but what if Joe and Jim have been working for a while on it and have accumulated actuals and are now behind schedule so I add Sally. In order for Sally to have baseline values, I have to rebaseline the task. If I do that, then the late work of Joe and Jim will suddenly be on track.
