Write one sentence for the process: “Given this input, perform these checks, produce this output.” Then list the data each step needs and what it will emit. Mark steps that can fail, require approval, or change external state.
Sketch the normal path first, then decide how empty input, malformed data, timeouts, and retries should behave. If a retry might send a second message or create a duplicate record, plan an idempotency key or review gate before building. Only then arrange the nodes in Workflows.
A diagram can clarify a good process; it cannot rescue an undefined one.
