Exception handling and workflow change control
Objective: Operate an AI workflow with visible exceptions, monitoring, rollback, version control, and a manual path when approved conditions are not met.
Define exceptions before launch: unavailable sources, unsupported formats, low-quality scans, conflicting instructions, sensitive data, policy gaps, high-impact requests, unusual volume, model outage, suspected prompt injection, or outputs that fail validation. The system should fail safely by abstaining, preserving the original input, and routing to an authorized person. Users need a clear way to report a wrong or harmful result and continue service without being forced through the same failure. Time-sensitive exceptions require ownership and service targets; a manual path that nobody staffs is not a control.
Every material change should have a request, reason, owner, affected components, risk review, test scope, approval, release record, and rollback plan. Changes include model versions, vendors, prompts, source sets, connectors, thresholds, user groups, and downstream actions. Monitor critical failures, overrides, abstentions, complaints, latency, cost, security events, and data-boundary breaches with thresholds that trigger investigation or pause. Preserve enough evidence to reconstruct an incident without retaining unnecessary sensitive content. Emergency changes still require after-action documentation. If the workflow drifts outside its intended purpose, stop or reclassify it rather than quietly expanding scope.
Before you begin
- Confirm F05, F06, F11, and F12; record that approved vendor controls, transfer authority, operating roles, monitoring thresholds, rollback package, exception authority, and production approval are absent.
- STOP. If vendor controls, transfer authority, operating roles, monitoring thresholds, rollback evidence, or exception authority is missing or conflicts with F05/F06/F11/F12, route the runbook to the accountable change authority and authorized specialist reviewers; do not claim production approval or execute a change, exception release, or rollback.
