BCWP Calculation

[Ritesh]

Hi

From Microsoft Project 2003 I understand BCWP is calculated as BCWS *
% Work Complete. I have the following queries:

1. In the Plan that I have, it is calculated as BCWS * % Complete (not
% Work Complete). Even if I change the Default Earned Value Method to
Physical % Complete, it still uses % Complete for Calculating the BCWP
value

2. Secondly even if % Work Complete is used, why should it be used in
BCWP calculations. % Work Complete is calculated as Actual Work / Work
* 100. If a resource puts in 100 hours of actual work and out of this
100, say only 75 hours contributes to the original baseline, then %
Work Complete value for BCWP calculations should be 75 and not 100.
However the way MSP calcultes, there is no difference between ACWP and
BCWP. How does MSP distinguish between ACWP and BCWP when whatever
Actual Work is charged is accounted in % Work Complete Calculations
and consequently in the BCWP calculations.

Appreciate any help on this query.

Then the Work Complete should be 75 hr, not 100. Put the other 25 on
whatever task that work went to. If the scope of the task expanded and the
25 h went to that expanded scope, you need to modify the schedule
accordingly and rebaseline. Project is not clairvoyant, and can't possibly
know without being told that 25 of those hours didn't go toward the
original baseline.

However the way MSP calcultes, there is no difference between ACWP and
BCWP. How does MSP distinguish between ACWP and BCWP when whatever
Actual Work is charged is accounted in % Work Complete Calculations
and consequently in the BCWP calculations.

Actual Cost is manually entered. BCWP is calculated, so they're not the
same unless the user makes them the same.

Hope this helps in your world.
