Keep each workflow doing one job

A workflow works best when it does exactly one thing, start to finish, without trying to also handle three other cases along the way. If you find yourself adding a branch for "unless it's this kind of order," that's usually a sign you need a second workflow, not a bigger first one.

Single-purpose workflows are easier to test, easier to turn off without breaking something unrelated, and far easier to explain to another person. I've inherited a workflow that tried to do everything, and it became a tangle nobody wanted to touch, including me, months on. Splitting things apart also means one small change to how you handle one case doesn't risk quietly breaking every other case bundled in with it.

Think of each workflow as a single tool in a drawer, not a Swiss army knife trying to cover every situation at once.

Try this today: look at your busiest workflow and see if one branch inside it deserves to become its own separate workflow.
