What is the kanban system and how does it help in improving workflow efficiency and visualizing work processes?

The Kanban system is a visual method for managing workflow in a way that helps teams prioritize tasks, limit work in progress, and improve efficiency. By using Kanban boards to visualize work processes, teams can easily see the status of each task, identify bottlenecks, and make informed decisions to optimize their workflow. This system helps teams to focus on completing tasks one at a time, reducing multitasking and improving overall productivity.
