Exception Path Design and Error Escalation (Delivery)
A sequence with 7 steps: Enumerate every failure mode the workflow can hit before the first client record moves through it.

What are the steps?
Exception Path Design and Error Escalation (Delivery)
- 01
Enumerate every failure mode the workflow can hit before the first client record moves through it
List API timeouts, auth token expiry, malformed payloads, duplicate records, and rate-limit rejections. A workflow with 3,000+ connector options still fails on the same handful of causes, so name them explicitly.
- 02
Assign each failure mode a cost tier based on what breaks downstream
A dropped lead notification costs a sales follow-up; a corrupted invoice sync costs a billing dispute. Tier 1 failures halt the run, Tier 2 failures queue for review, Tier 3 failures log and continue.
- 03
Build a dead-letter destination for every Tier 1 and Tier 2 failure
Route failed payloads to a dedicated table, sheet, or channel with the raw input, timestamp, and error message attached. Without this, debugging a client-reported miss means reconstructing history from memory.
- 04
Insert a human approval gate wherever an autonomous action touches money, client-facing messaging, or contract terms
Predictive systems now trigger actions without a human in the loop, so approval checkpoints on budget reallocation and outbound sends are a scoping decision, not an optional nicety.
- 05
Define the retry policy per step and cap it
Three retries with exponential backoff covers most transient API failures. Uncapped retries on a payment or CRM write step create duplicate records that cost more to clean than the original failure.
- 06
Write the escalation path into the client's shared channel with named owners
Specify who gets notified, within what window, and what they are expected to do. An alert with no owner is a log entry, not an escalation.
- 07
Run a forced-failure test on each Tier 1 path before go-live
Break the connection deliberately, confirm the dead-letter capture fires, and verify the escalation reaches a human. Document the test date in the delivery handoff.
