コードレビューはコアな協働プラクティスであり、それを上手に実施すること(フィードバックの提供と受け取りの両方)は重要な専門スキルです。良いコードレビューはコード品質を向上させ、知識を共有し、健全なチーム文化を構築します。一方、不適切に行うと摩擦が生まれます。
コードレビューを上手に実施する
✓ Be CONSTRUCTIVE and KIND → critique the CODE, not the person; assume good intent;
be respectful (reviews can feel personal)
✓ Be SPECIFIC and clear → explain WHY (reasoning, not just "change this"); suggest solutions
✓ Distinguish must-fix (bugs, security) from nitpicks/preferences (label them; don't block
on minor style)
✓ Praise good things too (not just criticism); ask questions vs demanding
✓ Be timely (don't block teammates); focus on what matters (logic, design, bugs, not just style)
コードレビューを上手に受け取る
✓ Don't take it PERSONALLY → feedback is about the code and improving it (separate ego)
✓ Be OPEN and grateful → it's a learning opportunity and a quality safeguard
✓ Consider feedback genuinely; ask for clarification if unclear; discuss respectfully
✓ It's OK to DISAGREE → explain your reasoning; find the best solution together (not winning)
✓ Learn from it → reviews are a great way to grow
