Original estimate and subsequent workitems

Question

Let say i have a CMMI bug in TFS2010 and I give it an original estimate of 40. I create 2 linked (child) work items of type Task and give it each an original estimate of 10 and 30.

Is this the right way to do ? Or should I only enter the original estimate on the leaf work items (thus: only on the tasks in this case) ?

Answer 1

I guess it depends on what you want to track. If you're tracking at the bug level, you'll likely want to track the original in both places. No matter what, you're going to have to keep the estimate to complete (ETC) updated on all tasks for appropriate reporting.
