Question-Related to COCOMO model – 4
Using the Basic COCOMO 81 model ‘see the tables and example below’, calculate the effort required – ‘in person-months’, the overall development time, and the number of personnel required for the project described below.
- Effort = a (KLOC)b. person month
- Development Time = c (Effort)d months
- Number of People = Effort / Development Time persons
| Software Product Type | a | b | c | d |
| Organic | 2.4 | 1.05 | 2.5 | 0.38 |
Assume that the size of an organic-type software product has been estimated to be 32,000 lines of source code. Determine the effort required to develop the software Product, its duration, and the number of personnel.
Solution:
We know that
Effort = a (KLOC)b. person month
Development Time = c (Effort)d months
Number of People = Effort / Development Time persons
Given that, estimated Lines of Code = 32,000 = 32 KLOC
Software Product Type / Modes of Development: Organic
Effort = a (KLOC)b person month
= 2.5 (32) 1.05 person month
= 95.13 person month
= 95 person month
Development Time = c (Effort) d Months
= 2.5 (95) 0.38 Months
= 14.1 Months
= 14 Months
Number of People = Effort / Development Time persons
= 95 / 14 persons
= 11.65 persons
= 6.78 persons
= 7 persons
