CAM Earned Value Management 5

Question 1

Under EIA-748 guidelines, retroactive changes to previously reported BCWS, BCWP, or ACWP are permitted only for what purpose?

Accepted Answer

Correcting errors, accounting adjustments, or customer-directed changes

Answer

EIA-748 restricts retroactive data changes to legitimate corrections and directed adjustments, never to alter apparent performance.

Question 2

A control account with a $400,000 BAC is 60% complete with ACWP of $270,000. What is the cost variance?

Accepted Answer

-$30,000

Answer

BCWP = 0.60 × $400,000 = $240,000, so CV = $240,000 - $270,000 = -$30,000.

Question 3

During a surveillance review, a CAM cannot explain the basis for claimed percent complete on a work package. What EVMS weakness does this indicate?

Accepted Answer

Lack of objective, verifiable criteria for measuring work accomplishment

Answer

Earned value claims must rest on objective, documented criteria; unsupported percentages undermine data integrity.

Question 4

What is the primary purpose of freeze period controls on the baseline?

Accepted Answer

To prevent changes to near-term budgets and schedules that would obscure current performance

Answer

Freeze periods restrict near-term replanning so current-period variances reflect real performance rather than baseline churn.

Question 5

Which corrective action is MOST appropriate when a CAM's variance analysis identifies a recurring labor rate overrun outside the CAM's control?

Accepted Answer

Document the driver, quantify the impact, and elevate it to program management for resolution

Answer

Drivers beyond the CAM's authority must still be analyzed, quantified, and escalated with recommended management action.
