CISA Practice Question: Information Systems Acquisition, Development, and Implementation

An IS auditor is reviewing a waterfall SDLC project that has completed the requirements phase. Which of the following is the greatest risk to the project?

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

A key business stakeholder did not sign off on the requirements.

In waterfall, requirements are defined upfront and changes are difficult. If a key stakeholder did not sign off, there is a risk that later phases will be based on incomplete or incorrect requirements.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • The project manager left the company.

    Why it's wrong here

    While impactful, it can be managed by reassignment; requirements sign-off is a critical control.

  • A key business stakeholder did not sign off on the requirements.

    Why this is correct

    Without sign-off, requirements may not reflect actual needs, leading to rework.

  • The development team is unfamiliar with the technology.

    Why it's wrong here

    This can be mitigated with training, but missing sign-off is more fundamental.

  • The design phase is behind schedule.

    Why it's wrong here

    Schedule delays are common but not the greatest risk compared to incorrect requirements.
