Physical percent complete methods

Manual entry, cost-based, effort-based and deliverable-based, and what each suits. The cost-based trap is the one to internalise: it is the easiest to automate and the least meaningful, because a task 80% spent may be 30% done and cost-based progress will never tell you. Design guidance is deliverable-based where deliverables exist, effort-based for labour tasks, manual only where nothing better applies. And the honesty point — whatever you configure, the number is only as good as the person entering it, and configuration cannot fix a culture where nobody reports bad news.
