In Scrum with Kanban, Flow is a central concept. It refers to a smooth and streamlined progression of work within a team. It is based on the philosophy of Lean, which focuses on minimizing waste and maximizing value creation.
To optimize it in the context of Scrum, it is important to define flow. In addition, the Scrum Team can optimize flow using the Kanban practices. By embracing these concepts, a Scrum Team gains more control over the work process and its predictability.
