EVM Cost and Schedule Variances and Performance Indices

Suppose you have a project consisting of three activities. Midway through the project you collect the following information:

Activity	PV	EV	AC
1	30	40	35
2	20	15	15
3	10	10	15

What is the project-level Schedule Variance (SV) and Cost Variance (CV)? What is the project-level Schedule Performance Index (SPI) and Cost Performance Index (CPI)?

Under what conditions would a positive variance and a performance index less than 1.0 occur simultaneously?

Topic 5b: Corrective Action

Describe any performance "thresholds" used by your organization to signal when corrective action is required to get a project back on track. If no "thresholds" are used, describe how your organization determines when to apply corrective action. In this context, use the PMI definition of corrective action - "an intentional activity that realigns the performance of the project work with the project management plan".

Option: If you work in an agile environment, describe when, in the process, corrective action is identified and how the effects of corrective action are assessed.
