control accounts in WBS

Hi,

I earlier had doubt on the Control Account & Code of account functions. but after reading the answers in PMZilla, it is well distinguished. But I wan to know that if Control Accounts will cater more than 1 work package then how the Progress/ Performance of that particluar work package or activities associated can be tracked eaither by EVM or any other means as it will have more than 1 work packages?Pl explain if possible give daigrams.

Thanks

 it is not compulsory

it may vary as per need or choice.

control account may have one or more than one work packages.

also EVM can be assessed at control account or at each workpackages or even at certain activities. or may be at mile stones.

it is so flexible.
