CISA Practice Question: A company has been developing a custom inventory…
A company has been developing a custom inventory management system using Scrum. In the current sprint, the team discovered that the integration module with the legacy ERP system has severe performance issues: under peak load, transactions time out and fail. The product owner is concerned because the release is scheduled in two weeks. The development team estimates that a proper fix will take three weeks. A similar issue occurred in a previous sprint and was temporarily resolved by reducing the number of concurrent transactions, which lowered performance but kept the system operational. The stakeholders are anxious about the deadline because the legacy ERP will be retired shortly after the planned go-live. What is the BEST action for the team to take?
⚠ Common exam trap
Candidates often choose Option D (workaround) because it seems pragmatic and avoids delaying the release, but they fail to recognize that the legacy ERP's imminent retirement makes a later permanent fix impossible, leaving the system with a critical, unresolved performance flaw.
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
✓
Delay the release by one week to complete the proper fix (three weeks total)
Delaying the release by one week allows the team to implement a proper, permanent fix for the ERP integration module's performance issue, which is critical given that the legacy ERP will be retired shortly after go-live. A temporary workaround would risk system instability and transaction failures under peak load, potentially causing data loss or corruption during the transition. The three-week estimate for a proper fix addresses the root cause, ensuring the system can handle peak loads reliably before the legacy system is decommissioned.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reduce the scope of the release to exclude the ERP integration feature entirely
Why it's wrong here
Excluding ERP integration would make the system incomplete and not meet business needs.
- ✓
Delay the release by one week to complete the proper fix (three weeks total)
Why this is correct
A one-week delay allows a proper fix, ensuring system reliability.
- ✗
Add two additional developers to the team to complete the fix within the original two-week timeline
Why it's wrong here
Adding developers may not speed up the fix and could introduce coordination challenges.
- ✗
Apply the same workaround for the go-live and plan a permanent fix in a later release
Why it's wrong here
The workaround reduces performance and may not handle peak loads.
