FC0-U71 Software Development Concepts Practice Question
A company is developing a mobile app and wants to release a minimal set of features quickly, then add more features based on user feedback. Which methodology best supports this approach?
⚠ Common exam trap
FC0-U71 often tests the distinction between iterative/Agile approaches and sequential/Waterfall or V-Model — the keywords 'minimal features quickly' and 'based on user feedback' are Agile signals.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Agile
Agile methodology emphasizes iterative development, frequent releases, and continuous feedback from users, which directly supports releasing a minimal set of features quickly and then adding more based on feedback. Agile's incremental and iterative nature aligns with the described approach.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Agile
Why this is correct
Agile delivers work in short iterations, releasing a minimal feature set early and adapting subsequent increments to user feedback. This directly satisfies the stem's requirement to ship quickly then evolve features, unlike waterfall's sequential, feedback-poor structure.
- ✗
V-Model
Why it's wrong here
The V-Model pairs each development stage with a corresponding verification phase, so requirements are fixed before build begins; it cannot deliver a minimal feature set and iterate on user feedback. It suits regulated, safety-critical projects where validation evidence must map to a frozen specification.
- ✗
Spiral
Why it's wrong here
Spiral iterates through risk-analysis cycles producing prototypes, but its emphasis is risk reduction across large, costly projects rather than shipping a minimal feature set for rapid user feedback. It is tempting as an iterative model, and would be correct where the dominant driver is managing high technical or cost risk.
- ✗
Waterfall
Why it's wrong here
Waterfall completes sequential phases with requirements fixed before build, so it cannot deliver a minimal feature set and then iterate on user feedback. It is tempting because it is a well-known, structured methodology, and it would be correct where requirements are stable, fully specified and regulatory documentation demands sequential sign-off.
