The Real Reason Your PRs Get Big

Short summary

Large pull requests stem from a teachable skills gap, not poor discipline—most engineers are never explicitly taught how to decompose complex features into independent, reviewable chunks. AI has removed the friction cost of code generation, making intentional decomposition training critical for teams. Teams that excel at PR decomposition achieve dramatically faster review cycles, catch significantly more bugs early, and maintain highly predictable delivery.

• •PR size is a skill, not a discipline—engineers need explicit training on decomposition
• •AI removed the friction cost of code generation, making decomposition training more critical
• •Teams with strong decomposition practices see faster reviews, fewer bugs, and predictable delivery
