For this exercise, assume that you are the DevOps lead of an organization/open-source community that uses GitHub to manage its projects under a GitHub Organization. GitHub Organizations are shared accounts consisting of members and projects with sophisticated security and administrative features. You have been asked to ensure that your organization's repositories are healthy such that there are no PRs in an unmerged state for more than one week, and every issue is either resolved or updated in 12 hours.
