A notification is not a completed workflow
Sending a message can be a useful step, but it does not tell you whether the recipient understood it or acted. Design the workflow around the result that matters. Name the action required, the owner, and the condition that marks the work complete.
Define the trigger precisely
A vague rule such as “send a reminder when something is late” hides important decisions. Which deadline? Which timezone? What if the task was completed but the source system is delayed? Write these conditions down before connecting a messaging service.
Make repetition safe
Retries are normal in connected systems. A service can receive a request even when its response gets lost. Use a stable identifier for the action so a retry does not create a second task or send a second message. Keep a record of what the workflow attempted and what the receiving system acknowledged.
Give exceptions a destination
When an address is wrong, information is missing, or a person cannot complete the task, assign the exception to someone who can help. A queue that nobody owns becomes another workaround. The administrator should see the reason, the relevant context, and the next available action.
Review the right signals
Review unresolved exceptions, repeated failures, and work that still needs manual intervention. These tell you where the process needs attention. A large count of messages sent is less useful if the underlying work remains incomplete.
