What is one element of the CALMR approach to DevOps?

Lean flow is one of the elements of the CALMR approach to DevOps in SAFe. It means applying lean principles and practices to optimize the flow of value from idea to production. Lean flow accelerates delivery by eliminating waste, reducing batch sizes, implementing pull systems, limiting work in process, managing queues, reducing handoffs, and applying cadence and synchronization. Lean flow enables faster feedback, shorter lead times, higher quality, and lower costs.
