Summary
William Yeh uses code review as a lens to examine six deeper engineering and team practices: foundational beliefs about quality, technical mastery and domain knowledge, team covenant consensus, collaborative understanding techniques, making progress visible, and sustainable engineering measures. The article argues that code review is not just a quality gate but a vehicle for collective ownership and knowledge sharing.
William Yeh 以 Code Review 為切入點，探討六個更深層的工程與團隊實踐：品質的基本信念、掌握基本功與領域知識、團隊公約共識、協同理解技巧、讓進步看得見，以及支持長久研發的措施。文章論證 Code Review 不只是品質把關，更是集體所有權與知識共享的載體。
Key Points
- Quality is built in through correct practices, not inspected out — code review reinforces this belief
- Collective ownership (XP principle): no single person owns any code; anyone can contribute to any part
- Lower bus factor (知識集中風險): code review forces knowledge distribution across the team
- Team covenants (coding standards, design principles) must be explicitly agreed upon, not assumed
- For engineers: focus on engineering disciplines (①②); for team leads: team dynamics (③④); for managers: visibility and sustainability (⑤⑥)
Insights
The distinction between code review as quality gate vs. code review as knowledge transfer mechanism reframes the common objection that “review slows us down.” When review is primarily about learning and collective ownership rather than catching bugs, the calculus changes. The structured reading guide (engineers read ①②, leads read ③④, managers read ⑤⑥) is a useful signal that code review has different value at different organizational levels.

品質是計畫、設計和內建而來的，不是靠檢驗出來的。換言之，品質來自正確地做事。
