A project is planned for an enterprise accounting system with an estimated size 60 KLOC. The organization applies Basic COCOMO (Semi-Detached Mode with parameters: )
Effort = 3.0 . (KLOC)1.0
Development time = 2.5 . (Effort)1/2
Average cost per person-month (pm) = $10,000
A contingency margin of 10% effort is mandatory
The client demands a detailed schedule if staff is capped at 15 engineers.
Including 10% contingency margin what is the project cost?
- A.
$ 1.80 M
- B.
$ 1.98 M
- C.
$ 2.4 M
- D.
$ 2.36 M
Attempted by 48 students.
Show answer & explanation
Correct answer: B
To determine the project cost, we first calculate the base effort using the Basic COCOMO formula provided: Effort = 3.0 * (KLOC)^1.0. With a size of 60 KLOC, the base effort is 3.0 * 60 = 180 person-months (pm). The problem mandates a 10% contingency margin on effort, so we add this to the base: 180 pm + (10% of 180) = 198 pm. Finally, we calculate the total cost by multiplying the adjusted effort by the average cost per person-month ($10,000). Total Cost = 198 pm * $10,000/pm = $1,980,000 or $1.98 million.",
