The Lean Thinking principle, “make value flow without interruptions” means identifying and eliminating any delays that prevent the smooth and fast movement of work product from step to step in a value stream. Delays are a form of waste that reduce the efficiency and effectiveness of the system, increase the lead time and cost, and lower the customer satisfaction. Delays can be caused by various factors, such as handoffs, queues, bottlenecks, rework, defects, approvals, dependencies, and variability. To make value flow without interruptions, SAFe applies the following eight flow accelerators: Visualize and limit WIP, reduce batch sizes, and manage queue lengths Implement full test automation and continuous integration Take an economic view Apply product development flow principles Understand and exploit variability Implement fast feedback and integrated learning Build quality in Base milestones on objective evaluation of working systems References: Principle #6 - Make Value Flow Without Interruptions - Scaled Agile Framework, Accelerating Flow with SAFe - Scaled Agile Framework
