3)The program manager (PM) considers that a difference of 5% between the cumulative cost performance index (CPI) and the to-complete performance index (TCPI) for the estimate at completion (EAC) indicates that an EAC may be unrealistic. What might you say about the contractor's EAC based on this test, given this chart?

(IMAGE DESCRIPTION: TCPI EAC chart. TCPI and CPI graphed over time from September through December. CPI is 0.857 and TCPI is 0.874.)

The CPI to TCPI comparison shows a difference of 8.74%, so the contractors EAC is not reasonable.

The trend of CPI is positive, so the contractors EAC is reasonable.

The CPI to TCPI comparison is negative, so the contractor EAC is not reasonable.

The CPI to TCPI comparison shows a difference of 1.7%, so the contractors EAC appears reasonable.

4)This excerpt from an IPMR provides what information?

(IMAGE DESCRIPTION: IPMR excerpt with schedule variance, or SV, data for the following WBS elements: WBS 1.1.7 Communications has negative 493 SV in dollars, and negative 35 SV in percent; WBS 1.2.2 Systems Engineering has negative 472.4 SV in dollars, and negative 27 SV in percent; WBS 1.1.2 Suspension/Steering has negative 326.8 SV in dollars, and negative 19 SV in percent; WBS 1.1.8 Integ. & Assembly has negative 51.6 SV in dollars, and negative 9 SV in percent; WBS 1.3.4 Test & Eval Support has negative 25.2 SV in dollars, and negative 17 SV in percent.)

This shows favorable schedule variances in $ and therefore identifies WBS elements that are helping to shorten the project schedule.

Since this data is only in dollars and percent, it doesnt have anything to do with schedule performance.

This shows unfavorable schedule variances in $ and %, which should be correlated with the IMS.

Since this data is in dollars, it must represent cost variances rather than schedule variances and therefore doesnt tell us anything about schedule performance.
