CS605 Software Engineering-II-assignment 3 idea solution
Q.
Let us assume that you are working as a Team lead in a renowned multinational company. The software project has 80 planned work tasks that are estimated to require 415 person-days to complete. At the time you have been asked to compute the Earned Value Analysis, 8 tasks have been completed. However, the project schedule indicates that 18 tasks should have been completed. The following scheduling data in person-days are available:
| Task | Planned Effort | Actual Effort |
| 1 | 3 | 3.5 |
| 2 | 4 | 5 |
| 3 | 5 | 5.5 |
| 4 | 4 | 3 |
| 5 | 6 | 7 |
| 6 | 7 | 6.5 |
| 7 | 5 | 5 |
| 8 | 7 | 7.5 |
| 9 | 8 | |
| 10 | 8 | |
| 11 | 3 | |
| 12 | 2 | |
| 13 | 14 | |
| 14 | 2 | |
| 15 | 7 | |
| 16 | 6 | |
| 17 | 8 | |
| 18 | 7 |
Compute the following
1) SPI
2) Schedule variance
3) Percent scheduled for completion
4) Percent complete
5) CPI
6) Cost variance for the project.

multinational company. The software project has 80 planned work tasks that
are estimated to require 415 person-days to complete. At the time you have

Compute the following
1) SPI
2) Schedule variance
3) Percent scheduled for completion
4) Percent complete
5) CPI
6) Cost variance for the project.
SOLUTION:
In order to calculate above quantities we have to compute this:
BCWS is the effort (person-days etc) for task so
= 3+4+5+4+6+7+5+7+8+8+3+2+14+2+7+6+8+7
= 106
BCWP = 3+4+5+4+6+7+5+7
= 41
BAC = 415
.
ACWP = 3.5+5+5.5+3+7+6.5+5+7.5
= 43
Now we needed all these values to compute above EVA.
1. SPI = BCWP/ BCWS
= 41/106
= 0.38
2. Schedule Variance= BCWP – BCWS
= 41-106
= -65
3. Percent Schedule for Completion = BCWS/BAC
= 106/415
= 0.25
4. Percent Complete= BCWP/ BAC
= 41/ 415
= 0.09
Percent Complete tells that 09% of the task has been completed. So we are 16 % left.
5. Cost Performance Index= BCWP/ ACWP
= 41/ 43
= 0.95
6. Cost Variance = BCWP – ACWP
= 41 – 43
= -2
Negative CV indicated that the project is over budget. -
