Inbox zero your pull requests, get to "PR Zero"

The text discusses strategies and tools used by a team to achieve "PR Zero," or having very few open pull requests. They accomplished this through encouraging smaller pull requests, reaching developers directly when reviews are critical, and celebrating progress towards PR Zero in Slack using Sleuth Automations. These automations help improve the efficiency of code review processes, reduce waiting time for developers, and promote better quality code by ensuring smaller batch sizes. The team also uses a daily summary of open pull requests to encourage prompt action on them.
