ITPEC IP October 2022 Question 50
ITPEC IP October 2022 — Question 50 of 100
Graph I represents staffing, and graph II represents correction cost. A waterfall project usually starts with a small team, grows through design, implementation, and testing, then declines near completion, matching I. A defect found later affects more completed work and documentation, so correction cost rises sharply over time, matching II.
Answer (a)
Why not others:
- III incorrectly suggests late corrections become cheaper
- IV's constant level does not represent the normal rise and fall of project staffing
- combinations using II or IV for staffing do not match lifecycle workload
Key rule: Waterfall staffing peaks in the middle, while the cost of correcting an early mistake increases the later it is discovered.
