CISA Practice Question: Is the PRIMARY benefit of using a prototype…
Which of the following is the PRIMARY benefit of using a prototype during system development?
⚠ Common exam trap
CISA often tests the primary purpose of a technique — candidates pick cost or speed benefits, but the exam expects the requirements-clarification rationale.
Answer choices

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Clarifying user requirements
A prototype is a working model built early to elicit and validate user requirements before full-scale development. Its primary benefit is clarifying and confirming what users actually need, reducing the risk of building the wrong system.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Clarifying user requirements
Why this is correct
A prototype gives users something concrete to interact with, exposing gaps and ambiguities in stated needs before full build. This early feedback loop reduces rework, making requirements clarification the primary benefit rather than cost, documentation, or code reuse.
- ✗
Accelerating coding
Why it's wrong here
Prototyping clarifies and validates requirements with users before construction, exposing misunderstandings early; it does not itself speed coding, which depends on design quality and tooling. Accelerating coding is the aim when schedules are tight and requirements are already stable and well understood.
- ✗
Minimizing documentation
Why it's wrong here
Prototyping primarily clarifies and validates user requirements early, reducing rework risk; it does not reduce documentation, and often adds to it. Minimising documentation is tempting because prototypes can substitute for written specifications in agile contexts, but that is a side effect, not the primary benefit sought here.
- ✗
Reducing development cost
Why it's wrong here
Prototyping primarily reduces requirement risk by confirming user needs early; cost savings are a possible downstream effect, not the principal benefit, and rework from a discarded prototype can raise spend. Cost reduction is pursued through reuse and estimation discipline, not through prototyping itself.
