Projects organize work beyond individual issues
GitHub Projects can provide table, board and roadmap-style views for planning work. Issues and pull requests can be organized into views with fields and filters.
Keep the workflow connected to development
A useful project board should reflect the real lifecycle of work, such as backlog, ready, in progress, review and done. Avoid creating columns that nobody maintains.
Automate repetitive movement
Where appropriate, repository activity can update project items automatically so developers do not have to maintain project state manually after every change.
