My project is 75% complete and I have no problem getting a nice view in MS Project showing the remaining critical path. However, I want a view that shows how we got to this point, in other words I want to see the full critical path of the project, including tasks that have already been completed at this point. Is there a way to clearly show this?
You are describing something like an as-built critical path, which is not easily created even in the best of circumstances.
- MSP sets the Critical flag based on total slack, but total slack becomes meaningless for completed tasks. Thus, completed tasks are never “Critical.”
- Conceivably, you could implement some very rigorous status-and-update procedures to memorialize the (future) critical path based on total slack at each update window – i.e. just before marking the task complete. Then at some future time you would be able to look back through your marks to “remember” which tasks were critical at the time of their completion. I don’t know of anyone who does this. Obviously, you can’t do this after the fact.
- You can also use a macro or an add-in to trace driving logic backward from a project completion milestone to the project start, including completed tasks if you like. I routinely use this approach, and it yields good insight, subject to the accuracy of the logic and the Actual Start and Actual Finish dates.
