One cool Agile tool is "Kanban", a visual management system that helps teams manage their workflow and identify bottlenecks in their process. It involves creating a visual representation of the work items and their status, and then using this information to optimize the process.

Kanban boards are a great tool for teams to visualize their work and make it easy to understand the progress and status of work items.

Additionally, Kanban allows teams to set up work-in-progress limits which help in managing the flow of work and avoid overloading the team with too much work at once.

It's a great way to improve efficiency and productivity while maintaining a steady workflow.
