CISA Practice Question: Which THREE of the following are common risks…
Which THREE of the following are common risks associated with the prototyping methodology?
⚠ Common exam trap
It's easy for candidates to confuse 'incomplete requirements specification' (a general risk) with a prototyping-specific risk, but the exam expects recognition that prototyping actually reduces this risk through iterative user feedback, while the three correct answers (B, C, E) are directly tied to the methodology's iterative and informal nature.
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
✓
Lack of adequate documentation
Prototyping often prioritizes rapid iteration over formal documentation, leading to incomplete or outdated records of system specifications, design decisions, and user agreements. This lack of adequate documentation creates risks for maintenance, knowledge transfer, and auditability, as the final system may lack the necessary artifacts for ongoing support and compliance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Incomplete requirements specification
Why it's wrong here
Prototyping helps clarify requirements, so this is less of a risk.
- ✓
Lack of adequate documentation
Why this is correct
Documentation is often overlooked in prototyping.
- ✓
Prototype being accepted as the final production version
Why this is correct
This is a common risk if prototyping is not managed.
- ✗
User misunderstanding of prototype limitations
Why it's wrong here
Users generally understand prototypes are not final.
- ✓
Scope creep due to frequent changes
Why this is correct
Frequent changes in prototyping can lead to scope creep.
