Question Related to COCOMO model – 1
Suppose that a project was estimated to be 400 KLOC. Calculate effort & time for each of 3 modes of development.
| Software Product Type | a | b | c | d |
| Organic | 2.4 | 1.05 | 2.5 | 0.38 |
| Semi-detached | 3.0 | 1.12 | 2.5 | 0.35 |
| Embedded | 3.6 | 1.20 | 2.5 | 0.32 |
Solution:
As we know that 3 modes of development are
- Organic
- Semi-detached
- Embedded
Also we know that
Effort = a (KLOC)b person month
Time = c (Effort)d Months
Here, we are given KLOC = 400
Organic:
Effort = a (KLOC)b person month
= 2.4 (400)1.05 person month
= 1295 person month
Time = c (Effort) d Months
= 2.5 (1295) 0.38 Months
= 38 Months
Semi-detached:
Effort = a (KLOC)b person month
= 3 (400)1.12 person month
= 2462 person month
Time = c (Effort) d Months
= 2.5 (2462) 0.35 Months
= 38.4 Months
Embedded
Effort = a (KLOC)b person month
= 3.6 (400)1.2 person month
= 4772 person month
Time = c (Effort) d Months
= 2.5 (4772) 0.32 Months
= 38 Months
