WIP stands for work in process, which is the amount of work that is currently being done in a system. One way to understand WIP is to make it visible to all stakeholders, using tools such as Kanban boards, cumulative flow diagrams, or burn-up charts. By making WIP visible, we can see the current state of the work, identify bottlenecks, limit WIP to match capacity, and improve flow efficiency.Reference:Principle #6 -- Visualize and limit WIP, reduce batch sizes, and manage queue lengths,Make Value Flow without Interruptions,SAFe Principle 6: Visualise and limit WIP, reduce batch sizes, and manage queued lengths
