Hi Alaa, I agree with Mike.
Hi Alaa,
I agree with Mike. -Make sure you get agreement in advance that this is acceptable before starting down this path.
I cannot tell you if it is contractually acceptable since I don't know anything about your contract, but if I was acting on behalf of the client I would need a very good reason to let you do this, because it is not good practise:
1) Makes it easier to hide unjustifiable changes to the programme
2) Makes it very difficult to compare revised vs orginal programme (different AIDs & potentially WBS / descriptions for the same activity)
3) Makes the schedule of changes you should be including with the revised programme more complex than it needs to be
4) Rolling up completed activities to a high-level summary instantly makes the programme invalid for any meaningful forensic analysis of historical performance
Cheers,
G
