Answer and Explanation:

Given:

Actual time (AT) = 70 days

Actual cost (AC) = $78,000

Scheduled cost (SC) = $84,000

Earned value (EV) = $81,000

Computation of cost variance:

Cost variance = Earned value - Actual cost

Cost variance = $81,000 - $78,000

Cost variance = $3,000

Computation of schedule variance:

Schedule variance = Earned value - Scheduled cost

Schedule variance = $81,000 - $84,000

Schedule variance = - $3,000

Computation of Cost schedule Index (CSI):

Cost schedule Index = EV² / (AC × SC)

Cost schedule Index = ($81,000)² / ($78,000 × $84,000)

Cost schedule Index = 1.00137363

Cost schedule Index = 1.001 (Approx)

Computation of time variance:

Time variance = (AT × CSI) - AT

Time variance = (70 × 1.001) - 70

Time variance = (70.07) - 70

Time variance = 0.07 days
