Andrew Sales, chief methodologist and SAFe Fellow at Scaled Agile, Inc. proposed 8 flow fundamentals for improving flow of customer value in SAFe systemically.
Visualizing and limiting work in progress improves team capabilities but does not solve the systemic problems of flow at higher levels.
Addressing bottlenecks can be done by increasing capacity, replanning work or learning new skills, but first move to the right on the Org Topologies map to make teams more specialized.
Minimizing hand-offs and dependencies can be achieved by reorganizing around value at ART or Solution level, or by redefining the system design for cross-functional teams.
Getting fast feedback requires improvements in technical feedback loops, automation, and more frequent customer reviews at ART level or higher.
Working in small batches is essential, and proposed solutions include creating different delivery types or becoming a team of teams that work on issues at the customer level to enable vertical slicing.
Managing queue lengths involves not committing beyond the current Program Increment and focusing on less informal work. Removing team backlogs and letting a team of teams coordinate work can also speed up the system.
Optimizing time in the zone is made possible through optimizing meetings and events, keeping WIP low, and using collaboration patterns such as pairing and mobbing.
Finally, remediation of legacy policies and practices may require systemic thinking using the Org Topologies map.
