Assume the following regarding the development of a software system P :
- Estimated lines of code of P : 33, 480 LOC
- Average productivity for P : 620 LOC per person-month
- Number of software developers : 6
- Average salary of a software developer : ₹ 50,000 per month
If E, D and C are the estimated development effort (in person-months), estimated development
time (in months), and estimated development cost (in ₹ Lac) respectively, then (E, D, C)
=_________.
- A.
(48, 8, 24)
- B.
(54, 9, 27)
- C.
(60, 10, 30)
- D.
(42, 7, 21)
Attempted by 108 students.
Show answer & explanation
Correct answer: B
Solution: compute effort, time, and cost for the project.
Estimated effort (E): E = Total LOC ÷ Productivity = 33,480 ÷ 620 = 54 person-months.
Estimated development time (D): D = E ÷ Number of developers = 54 ÷ 6 = 9 months.
Estimated development cost (C): C = E × Salary per person-month = 54 × ₹50,000 = ₹2,700,000 = ₹27 lac.
Therefore the correct triplet (E, D, C) is (54, 9, 27).
