Question

The traffic control system inside Riyadh city is not meeting the expectations of the city traffic police. The system is to be updated within a few weeks to incorporate the traffic intensity, the weather conditions and the VIP movements etc. The entire project is to be completed within 10 weeks as per the following schedule:

Task ID	Task	Allocated Time (Weeks)	Budget (SAR)
TID-10	Requirements elicitation	1	10,000
TID-11	Use-case Development	1	10,000
TID-12	Process Model Development	1	10,000
TID-13	Data Model Development	1	10,000
TID-20	Architecture-Level Design	1	10,000
TID-21	User-Interface Design	1	10,000
TID-22	Algorithm Design	1	10,000
TID-23	Data Storage Design	1	10,000
TID-30	Programming	1	10,000
TID-31	Quality Assurance	1	10,000

At the end of Week 7 of the project you have completed only first six tasks (i.e. you just finished, TID-21 i.e. Data Model Development) with a total of SAR 67,500 spent to date. The Interior Minister asks you to produce a report on the status of project work with the help of earned value method. In particular you are asked to include answers to the following questions in your report:

1. What is the cost variance (CV), cost performance index (CPI), schedule variance (SV) and schedule performance index (SPI) for the project so far?
2. How is the project doing? Is it ahead of schedule or behind schedule? Is it under budget or over budget?
3. Use the CPI to calculate the estimate at completion (EAC) for this project. Is the project performing better or worse than planned?
4. Use the SPI to estimate how long it will take to finish this project.

Use the earned value management (EVM) in the given scenario answering each of the abovementioned question separately.

thank you for time and effort
