Decide what a workflow should measure and wire it in — flow measures (WIP, age, cycle time, throughput, rework), evidence measures (coverage, first-pass yield, escape rate, check agreement), leverage measures (delegate mix, human minutes per item, escalation rate, cost per item), and the outcome measure the stream exists for — with each measure named on the steps that feed it and a baseline taken before anything changes. Use when defining a workflow, when a board has numbers nobody steers with, or before making any workflow-improvement bet. Part of the flow-driven family.
