Code integrations give Sleuth access to your code repositories. Sleuth analyzes your pull requests, commits, files and authors to provide a meaningful and clear view of the changes you make in code when you deploy.
Developing off trunk rather than on long-lived branches is correlated with higher delivery performance
If your teams create short-lived branches that are merged into a core branch (trunk, main, master) at least daily then you're working consistent with commonly accepted continuous integration best practices. Sleuth is an excellent tool for your team.
If your team is small or nimble enough to commit directly to one branch, more granular data may not be available or relevant (e.g., review time and review lag time in change lead time) depending on your process and provider. However, Sleuth will still surface the important metrics to help your team succeed in its software delivery optimization goals.
