ITPEC IP April 2020 Question 47
ITPEC IP April 2020 — Question 47 of 100
The function point method estimates system size from user-visible functions such as inputs, outputs, inquiries, interfaces, and logical files. Each function is counted and weighted by complexity, providing a size measure largely independent of programming language.
Answer (b)
Why not others:
- summing WBS activity estimates is bottom-up estimation
- estimating from lines of code is a code-size productivity method
- adjusting from a similar past system is analogy-based estimation
Key rule: Function points measure delivered functional size rather than source-code volume or task-by-task effort.
