todolist#22 Control accounts
Sometimes while estimating the effort required at a work package level, we may not have complete information to decompose some of the work packages into activities (may not have complete information).
Example : - I am estimating for a software to be delivered in Jan 2009 and the RDBMS should be the then latest Oracle RDBMS the price of which is not known now. Still I may have to start work on it, without knowing how much it is going to cost.
In these circumstances, we open a control account (a provisional account) for those work packages, whose actual estimates are not yet known - and the work continues. Workpackages operating with a control account are definitely high risk items, and should be given top priority while monitoring and controlling them.
