This document discusses code review patterns and improving code review practices. It describes several code review problems or constraints teams commonly face, such as unclear review contexts, inefficient review coordination, and lack of review metrics. For each problem, it proposes a potential pattern or solution, such as defining review contexts upfront, conducting team reviews to improve quality, and tracking review counts and time spent. The document advocates adapting and combining these patterns to fit each team's unique needs rather than copying practices from other teams. It also encourages challenging existing practices and aiming higher with code reviews.
