Re: Bcwp/bcws

All of this is great; I tried to give emilslx a most simple example. There
is one point in your post I disagree with:
It is incorrect to say "Cumulative BCWP never exceeds BCWS."

I see cBCWP>cBCWS frequently.
SPI=BCWP/BCWS

If SPI exceeds 1.0 (you are ahead of schedule) then BCWP will exceed BCWS.
This is true for both monthly and cummulative data. At the end of the
contract cBCWP=cBCWS since you cannot earn more than you scheduled on a
cummulative basis at the end. Actually, it would be OK to call it quits any
time during the contract --- if that were to happen when BCWP>BCWS then you
would be in an odd situtation. You would have to take some adjustments to
get the two equal at close. If cBCWP<cBCWS at close, then you would write
down cBWCS to reflect cBCWP at close.

It would be fair to say, "Murphy's Law will not allow BCWP to exceed BCWS"

Hi emilslx,

Welcome to this Microsoft Project newsgroup :)

Scheduled work is what you planned to happen, and work performed is what
actually happened.

Dear friends,

I can't understand the difference between BCWP and BCWS. Budgeted cost
of works performed and works scheduled. At the first sight, they are
the same. Can anybody bring examples or explain in which cases they may
differ?

Thank you!
Emil

The term BCWS is really the time phased budget for scheduled work and
is usually plotted over time. It may be related to the bid for a job,
or not. In formal EVM BCWS excludes profit and contingency funds. If
your schedule is resource loaded and costed then the planned cost is
the BCWS for each period, and cumulative. BCWP is portion of BCWS you
"earn" for getting work done. An objective and independent assessment
of the percent complete for each task underway provides the BCWP for
the task. Independent means without regard to the time, staff-hours,
or funds spent on the task since none of these data give any insight
to what was really accomplished. Cumulative BCWP never exceeds BCWS.
ACWP is just the incurred cost. PV, EV, and AC are generally replacing
the BCWS, BCWP, and ACWP terms. Other books include the PMI Practice
Standard on EVM and my book at http://www.managementconcepts.com/publications/project_management/evm3.asp.
