Let us consider an IT project P scheduled for 6 months where: Project team must develop two activities a month for 6 months • Each activity is planned to cost 50 $ • We observe the project at the beginning of month 5 and we find that 10 activities are already finished, and that CPI is equal to 0.4. 1. How is the project performing from a schedule perspective? 2. How is the project performing from a cost perspective? 3. What is the actual cost of the project? 4. If we assume that the COST variance experienced in the project will continue, how much more money will it take to complete the project? 5. If we suppose that the variance experienced were to stop, what is the project's estimate at completion? 6. What is the project's TCPI using the project's budget at completion? 7. If the project manager focuses on the percentage of the project that is complete. What should he/she report? 8. Imagine that instead of 5 months and actual cost…
