THE STARTING POINT
Design automation fallback rules for unavailable systems, invalid inputs and uncertain outputs. Assign recovery ownership and test the manual route.
List the interruptions.
Consider missing inputs, unavailable systems and outputs that cannot be accepted. Describe what happens to work already in progress when a dependency fails. Distinguish a temporary delay from a case requiring a business decision, so the workflow does not treat every interruption as an automatic retry.
Keep a usable manual route.
Identify what information a person needs to continue the task safely. Make pending work and completed actions visible to avoid duplicate processing. Discuss how the manual route will be rehearsed during the pilot rather than assuming someone can reconstruct the task when the automation stops.
Review recovery ownership.
Assign responsibility for resolving exceptions and deciding when automated processing can resume. Record the checks needed to reconcile manual and automated work. A fallback should be part of the workflow’s operating instructions, not a separate document that nobody knows to consult.
Work through failure before expanding the workflow
List where a task can fail: input validation, an unavailable dependency, an uncertain result or a partially completed action. For each point, determine whether the system knows that nothing happened or whether the outcome is uncertain. That distinction affects whether a retry is safe.
Describe the manual continuation route and the information needed to use it. Assign an owner to unattended failures and agree how they are visible. Test interruptions at different stages, including recovery after a service becomes available. Reconcile the final state so a task is not lost, repeated or left permanently pending. Keep fallback instructions close to the operating workflow rather than only in a development note.
A fallback and recovery decision sheet
Use a row per failure category. Confirm the proposed response with both the business owner and the technical operator.
- Failure point: input, dependency, processing step or downstream action that may fail.
- Known state: what has definitely completed and what remains uncertain.
- Automatic response: stop, retry, defer or reject, with conditions and limits.
- Manual response: responsible role, context provided and available continuation actions.
- Communication: useful user status, operator notification and escalation when unresolved.
- Reconciliation: how the team confirms the eventual outcome and prevents duplicate work.
Do not retry every failed action in the same way
A repeated read and a repeated payment instruction have different consequences. Identify actions that need duplicate protection or a status check before another attempt. Keep error messages useful enough for the operating team to distinguish rejection from uncertainty.
Avoid a manual fallback requiring information the system has discarded. Preserve the necessary context within the approved access and retention arrangements. A queue of failed tasks also needs ownership; making errors visible without assigning a response does not complete the recovery design.
Should a fallback always be automatic?
No. Some failures are better paused for a person, particularly where the next action could create an irreversible or duplicate outcome. Choose the response around the task’s consequences and the information available, then verify that the operating team can carry it out.
ILLUSTRATIVE PLANNING EXAMPLE
Example: an unavailable external service
An automated workflow sends a request to an external service that times out. Decide whether retrying is safe, how duplicate actions are prevented and when a person is notified. Provide enough context for the person to complete or cancel the task without starting again from an unexplained error message.
Test the fallback with the operating team. Record the retry limit, escalation owner and reconciliation step before increasing the workflow’s scope.
