DPI Continual Improvement Practice Question
An enterprise service management team is utilizing value stream mapping to analyze their change enablement process. They discover that 40% of total lead time is spent waiting for peer code reviews due to developer availability bottlenecks. According to ITIL guidance on continual improvement methods, what is the most appropriate corrective improvement action?
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
✓
Implement automated static code analysis tools and cross-train team members to alleviate the peer review bottleneck.
Bottlenecks caused by human resource constraints in value streams should be addressed by improving throughput, cross-training, automating reviews where possible, or optimizing the workflow across the 'Organizations and people' and 'Value streams and processes' dimensions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the severity threshold for major incident reporting.
Why it's wrong here
Incident severity thresholds are unrelated to code review bottlenecks in change enablement.
- ✗
Outsource all coding tasks to an offshore partner without changing the review process.
Why it's wrong here
Outsourcing without addressing the review bottleneck will simply shift the delay downstream.
- ✗
Eliminate code reviews entirely to maximize change velocity.
Why it's wrong here
Eliminating reviews compromises quality and governance, introducing unacceptable risk.
- ✓
Implement automated static code analysis tools and cross-train team members to alleviate the peer review bottleneck.
Why this is correct
Automation (tooling) and cross-training (people) directly address review bottlenecks without sacrificing quality.
