Sending a message is only one part of the task.\n\nA useful place to start an automation is the handoff. What information should move? Where should it go? Who needs to know when it cannot move? Those questions make the next step easier to describe before choosing a tool.\n\nFor example, a service business could keep the appointment record in one place and use that record when preparing a reminder. If the time changes, the reminder should follow the current record. If a phone number is missing, that exception needs somewhere visible to wait for a person.\n\nThe same thinking applies to a content queue. A generated draft, an approved version and a published post are different states. Keeping them separate helps the author see what still needs a decision. An approval should mean a person has chosen the words, the destination and the time.\n\nA good first test is small enough to inspect. Take one example through the normal path, then change a detail or interrupt the connection and see what happens. A neat diagram is useful, but the recovery step is part of the workflow too.\n\nStart by writing down one handoff that keeps getting repeated. Name the information, the next owner and the exception. Then choose the tool that makes that movement easier to follow.",
