Question

You have been provided with 13 cases as below, explain what you can interpret from the provided data for each case?

What impact would be there on Budgeted Cost of Work Scheduled, Budgeted cost of work performed, Actual Cost of Work Performed and cost and schedule variances as a result of:

a. Early start of an activity on a PERT Chart?

b. Late start of an activity on a PERT Chart?

Planned Earned Actuals ACWP) Value (BCWP) Actual Earned Case Value (BCWS) 800 800 600 400 800 800 800 800 1,000 600 1,000 1,000 600 1,200 1,000 1,000 1,000 800 800 800 800 800 800 800 ,000 ,000 1.200 12

Explanation / Answer

-------------------------

a. Early start of an activity on a PERT Chart?

BCWS cannot change. It is immune to actual reality. It is only a planning figure.
BCWP will more than BCWS now.
ACWP is related to the actual cost of the work performed. So, shifting of schedule will change this just equal to the change in BCWP.

So, SV will be positive. CV will be zero.

b. Late start of an activity on a PERT Chart?

BCWS cannot change. It is immune to actual reality. It is only a planning figure.
BCWP will less than BCWS now.
ACWP is related to the actual cost of the work performed. ACWP is related to the actual cost of the work performed. So, shifting of schedule will change this just equal to the change in BCWP.

So, SV will be negative. CV will be zero

Case BCWS ACWP BCWP SV = BCWP - BCWS CV = BCWP - ACWP Interpretation
