ITPEC FE Morning October 2019 Question 52
ITPEC FE Morning October 2019 — Question 52 of 80
Project Effort Estimation — estimate total person-days using a size/complexity matrix plus overhead.
Step 1 — Creation effort:
- Small / Low: 30 × 0.4 = 12
- Medium / Medium: 40 × 0.9 = 36
- Large / Medium: 20 × 1.0 = 20
- Large / High: 10 × 1.2 = 12
- Subtotal: 80 person-days
Step 2 — Add review & revision: 80 + 5 = 85
Step 3 — Project management = 20% of total person-days including review:
- 0.2 × 85 = 17
Total = 85 + 17 = 102
Why not others:
- (a) 80 — creation only, missing review and management
- (b) 85 — missing the 20% management overhead
- (c) 101 — calculated management as 20% of creation only (0.2 × 80 = 16, then 80 + 5 + 16 = 101)
Key rule: "including X" after a percentage base means X is part of the base for that percentage, not separate from it. Here: management base = creation + review = 85.
