I have set my baseline and am tracking progress. I find that my variance is high, so during the review meeting with management, i get an okay to replan the activities. So do i set another baseline and track progress based on this? Do i revise my baseline everytime i find that am unable to meet my schedule? Also can you give me some thumb rules as to when to rebaseline, when to use interim plan, when to reschedule work?
I think rebaseline is only when scope changes or any other scenarios also?
Rebaseline is due to approved change request which includes scope, time, cost and quality impact. The change request are approved if there are no options to meet the original baseline.
When updating the baseline, ask yourself : “Is all the task approved again (or) only selected tasks are approved?”. This help you to decide whether to select either “Entire Project” or “Selected Tasks” in Set Baseline dialog
Interim Plan is used to backup baseline information or backup the current Start and Finish date. For instance, before updating the baseline if you need to have a backup of the current baseline, you copy Baseline to Baseline 1 (… Baseline 10) by select Interim Plan in Set Baseline dialog and selecting Copy: Baseline and Into: Baseline1. Another instance the interim plan will be useful is when you want to see the effect of the recent update on the current start and finish date. You can copy Start/Finish to Start1/Finish1, update the estimates/actuals, and compare the current Start, Finish with Start1 and Finish1.
