AI-assisted software development with redesigned code-review controls
A six-person engineering team used AI coding agents to increase pull requests from about 31 to 68 per week, but median merge time rose from roughly 4 to 14 hours and P90 reached five days. The team introduced smaller diffs, explicit human verification, explain-back requirements, and separate commits for AI-generated code versus human judgment, reducing median merge time to about six hours.

Verdict
High-value case for teams facing a similar quality / throughput problem. Implementation effort is medium effort, so it is worth prioritizing when the workflow pain is recurring, measurable, and owned by a team that can execute.
Should You Care?
Yes, if
- Worth considering if Software development is already losing value to this problem.
- Move faster if quality speed is measurable in your current operation.
- Relevant when the task is close to: Generate software changes with AI and review, validate, and merge the resulting p...
No / wait, if
- Pause if this limitation applies: AI-generated code was uniformly plausible and harder to assess for intent, generated tests...
- Wait if ownership, compliance, or implementation capacity is unclear.

Implementation Risks
- AI-generated code was uniformly plausible and harder to assess for intent, generated tests could encode the same requirement misunderstanding as the implementation, and the AI reviewer bot produced additional low-value comments while missing a significant performance issue
- Human review remained the bottleneck.

Quality / throughput
Medium effort
AI agents accelerated code generation faster than the team's fixed human review capacity, creating larger pull requests and a review queue. An AI reviewer bot added more text but did not identify important issues such as an N+1 query.
Generate software changes with AI and review, validate, and merge the resulting pull requests safely.
-
- PR volume increased from about 31 to 68 per week
- median diff size grew from about 90 to 310 lines
- median time-to-merge initially increased from about 4 to 14 hours, with P90 rising from 1.5 to 5 days
- After enforcing a 400-line diff cap, requiring a human verification section, applying an explain-back rule, and separating mechanical and judgment commits, median merge time fell to about 6 hours.

- Implementation effort
- The technical piece is only part of the work; the harder question is ownership, monitoring, and rollout discipline.
- Practical read
- Best read as a medium effort operational change with ROI upside when the pain is already measurable.
