percent complete / progress comparison

[Lorderon]

Hi,
I have a schedule (baseline, let's call it Schedule A) wherein it was the
original schedule submitted to the client. In this schedule resources are not
loaded and it is simply showing the Start / Finish date of every tasks and
the work (budgetted units) per task.

Now, I have an actual schedule (let's call it Schedule B) which we are now
using to enter the actuals.

Question is if I want to know our progress in comparison to Schedle A, how
to do it? Say today is June 6 and each tasks on Schedule B has some percent %
complete how to compare it to Schedule A?

Just like this....
Schedule A:
Task 1: Build wall, Start (May 30), Finish (June 7) = meaning by June 7
should be 100% complete

Schedule B:
Task 1: Build wall, Actual Start (May 30), actual percent complete only 20%
(today is June 6)

So, how to know the percent complete of Task 1 in Schedule A as of June 6?
Like asking a question, if our actual percent complete is 20% as of June 6
(as per Schedule B), how many % complete we should have been as per the
target on Schedule A? If our progress is only 20% how is it compared to the
original schedule we submitted to the client?



Thanks.
