Introducing FlexReview Teams and SLO is a system designed to manage code reviews and team ownership in a team-based culture. It provides a customizable framework for managing code review rules, assignments, and notifications, allowing teams to establish their own policies and objectives while facilitating inter-team best practices. The system uses a Team representation that can be mapped with a unique GitHub Team and inherits the configuration from its parent team. A Service Level Objective (SLO) for code review defines the suggested time it should take the reviewer to respond to a code change, incentivizing authors to create smaller PRs and reviewers to stay on top of PRs. The system supports three configurations for reviewer assignment: expert reviewer, oncall reviewer, and load balanced, as well as automated rules for stale PRs and review reassignment. A team's SLO dashboard provides real-time insights into code review response times, highlighting areas for improvement and ensuring compliance with set objectives.
