Connected systems work best when each handoff is explicit. Clear inputs, predictable results, and useful feedback help people understand what happened and what to do next.
- Define the event and the required information.
- Make retries safe and recognizable.
- Give people clear progress and recovery messages.
Make the next step predictable
Start by naming the information that moves between systems and the event that triggers the transfer. Avoid relying on a field or status that changes meaning in different tools. A simple, documented contract makes the connection easier to maintain.
Plan for a request to arrive more than once. A repeated event should not create duplicate work. Use stable identifiers and keep the result of an action available so the system can recognize a retry.
Design feedback for the person using the workflow. A useful status explains whether the action is pending, complete, or needs attention. When something fails, preserve the information they entered and describe a practical next step.
Test the handoff under ordinary and exceptional conditions. A slow response, an unavailable service, or a missing field should produce a controlled result that the team can understand.
