ITPEC FE Morning April 2020 Question 52

Staff allocation — peak staffing calculation — find the phase with the highest staff count.

Given: 200 person-months total, 10-month project.

For each phase, compute staff = (total_effort × effort%) / (total_duration × time%):

• •Requirements: 200 × 0.16 / (10 × 0.20) = 32 / 2 = 16
• •Design: 200 × 0.33 / (10 × 0.30) = 66 / 3 = 22
• •Dev/Test: 200 × 0.42 / (10 × 0.40) = 84 / 4 = 21
• •System test: 200 × 0.09 / (10 × 0.10) = 18 / 1 = 18

Peak staffing = 22 (Design phase).

Why not others:
- (a) 18 — System test staffing, not the peak
- (b) 20 — no phase yields this value
- (c) 21 — Dev/Test phase, but Design is higher at 22

Key rule: staff_per_phase = (total_effort × effort_%) / (total_time × time_%). The peak is the maximum across all phases.
