Section
5-1 Project management
Answer
Explanation
The person-months needed to make the changes can be found by dividing the number of programs to be modified by the volume of work in one (1) person-month.
First, find the number of programs to be modified using the following formula:
5,000 × 20% = 1,000
Next, find the volume of work in one (1) person-month by multiplying the number of programs that can be modified in one (1) day by one (1) programmer by the number of work days
in a month:
0.2 × 20 days = 4
Therefore, the number of necessary person-months is found using the following formula:
1,000 programs ÷ 4 = 250 person-months
