Comprehensive and Detailed 250 to 250 words of Explanation From Exact Extract of SAFe 6.0, including the SAFe Release domains:
In SAFe 6.0, identifying and removing bottlenecks is essential to improving flow and accelerating value delivery across the Agile Release Train. One of the primary tools used to identify bottlenecks is Value Stream Mapping. This Lean technique visualizes the end-to-end flow of work, information, and value from concept to delivery, making delays, handoffs, queues, and constraints visible. SAFe emphasizes value stream mapping as a critical practice for optimizing the Continuous Delivery Pipeline and improving system-wide flow.
By mapping each step in the value stream, ARTs can clearly see where work accumulates, where cycle times increase, and where rework or waiting occurs. This insight enables teams and leaders to focus improvement efforts on the most impactful constraints rather than optimizing isolated components. Value stream mapping directly supports SAFe’s Flow Accelerators, particularly “Identify and optimize the bottleneck” and “Eliminate handoffs and non-value-added work.”
While Kanban boards help visualize and manage flow within a defined process, value stream mapping goes further by examining the entire system across organizational boundaries. OKRs are strategic alignment tools and do not identify operational bottlenecks. Ishikawa diagrams are useful for root cause analysis but are not the primary tool for visualizing flow constraints across a value stream.
Therefore, Value Stream Mapping is the SAFe-recommended tool for identifying bottlenecks and enabling continuous flow improvement within the Release domain.
