CISA Practice Question: When implementing a commercial off-the-shelf…
When implementing a commercial off-the-shelf (COTS) software package, which of the following is the MOST important activity to ensure the software meets business requirements?
⚠ Common exam trap
It's easy for candidates to confuse vendor demonstrations with functional validation, assuming a demo proves the software fits all requirements, when in reality demos are scripted and omit edge cases that a gap analysis would expose.

Correct answer & explanation
✓
Performing a gap analysis between requirements and software features
Performing a gap analysis is the most important activity because it systematically maps each business requirement against the COTS software's delivered features, identifying any shortfalls that must be addressed through configuration, customization, or process adaptation. Without this structured comparison, the organization risks deploying software that fails to support critical business processes, leading to costly rework or project failure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Conducting a vendor demonstration
Why it's wrong here
A vendor demonstration shows scripted functionality in a controlled environment, not evidence that the package satisfies the organisation's documented requirements or integration constraints. Demonstrations are useful during early market scanning to shortlist candidates, but requirement verification demands structured evaluation such as a fit-gap analysis against defined criteria.
- ✗
Developing a project plan with milestones
Why it's wrong here
A milestone plan schedules delivery activities; it does not establish whether the package's functionality satisfies the stated business requirements. Project planning is correct once a solution is selected and implementation must be tracked, but requirement verification depends on evaluating the package's fit against documented criteria.
- ✓
Performing a gap analysis between requirements and software features
Why this is correct
A gap analysis systematically compares documented business requirements against the COTS package's delivered features, exposing shortfalls, customisation needs and integration risks before commitment. This directly determines whether the software actually satisfies business requirements, unlike testing or vendor references performed later.
- ✗
Reviewing the software's technical architecture
Why it's wrong here
Reviewing technical architecture addresses infrastructure compatibility and scalability, not whether the package's functionality matches documented business requirements. Architecture review is the right activity when assessing integration, hosting or performance constraints, but requirement fulfilment is verified through structured evaluation against defined business criteria.
