Assume that a software system P is to be developed with the following parameters:
Estimated size of the software: 33,480 LOC
Productivity: 620 LOC per person-month
Number of developers available: 6
Salary of each developer: Rs. 50,000 per month
Find (E, D, C), where E is the effort in person-months, D is the development time in months and C is the total cost in lakhs of rupees.
Pick an option to check yourself, or open the answer below.
Show answer & explanation
Correct answer: B. (54, 9, 27)
Explanation
Effort E = size / productivity = 33,480 / 620 = 54 person-months. With 6 developers working in parallel, the development time D = E / 6 = 54 / 6 = 9 months. The cost is effort multiplied by the monthly salary, C = 54 × Rs. 50,000 = Rs. 27,00,000 = 27 lakhs. Hence (E, D, C) = (54, 9, 27), which is option (2).More Database Management Systems questions
