Knowledge transfer is the deliberate movement of knowledge from one person or group to another. In software teams, code reviews turn that movement into a routine part of development while reducing dependence on individual experts. section 1.3.2 section 3.1.3
Use code reviews and everyday collaboration to distribute knowledge deliberately:
- Set knowledge transfer as an explicit review goal alongside bug finding, maintainability, mentoring, and recordkeeping. section 3.1
- Capture the change’s rationale in the pull request, including what changed and why. section 1.3.2
- Combine reviews with development conversations, team meetings, and informal pair programming so learning starts before submission. section 3.1.3
- Spread understanding across the team to improve the Vacation Factor and make absences less disruptive. section 3.1.3
A review that transfers knowledge
A long-standing developer reviews a change with a newer teammate, explains a codebase quirk and the reason behind the design, and records that rationale in the pull request. Future teammates can use the review history instead of relying on that developer’s memory. section 1.3.2 section 3.1.3
