ITPEC FE Morning April 2023 Question 55
ITPEC FE Morning April 2023 — Question 55 of 80
FP counts five element types: external inputs, external outputs, external inquiries, internal logical files, and external interface files. Each element is weighted by complexity, then a complexity adjustment factor is applied to get the final FP count.
Why not others:
- (a) — describes WBS-based estimation (breaking work into items with standard workload values)
- (b) — describes COCOMO (estimating person-hours and duration from known development scale, applicable beyond business)
- (c) — describes estimation by analogy (comparing with similar past software projects)
Key rule: FP measures what the software does for users (I/O, files, queries), not lines of code or work packages.
