Detect degraded behavior, recover deliberately, and communicate clearly when an AI application fails.

Detection leads to impact assessment, containment, and verified recovery. A postmortem produces owned improvements to prevention and detection.
Respond with containment and evidence. Detection leads to impact assessment, containment, and verified recovery. A postmortem produces owned improvements to prevention and detection.
Module 18 / Lesson 01

Define meaningful service indicators

Choose indicators tied to user outcomes: successful completed tasks, evidence freshness, latency, unavailable dependencies, and blocked unsafe actions. Raw request volume alone says little about usefulness.

Service objectives need a defined window and workload. Separate an application failure from an appropriate refusal of an unauthorized request. A denied attack should not automatically be counted as a product defect.

Apply the ideaDefine three indicators with numerator, denominator, window, and owner.
Module 18 / Lesson 02

Create actionable alerts

An alert should identify a condition worth human attention and provide a first diagnostic step. Combine sustained symptoms with relevant context to reduce noise. Differentiate a single transient retry from a prolonged loss of service.

Link the alert to a runbook. Include safe identifiers, environment, recent changes, and relevant dashboards. Avoid putting customer text in notifications simply because it is available.

Apply the ideaWrite an alert for stale indexed policies with a useful runbook entry point.
Module 18 / Lesson 03

Triage and contain

During an incident, first establish impact and contain harmful behavior. Stop unsafe writes, disable a failing feature, or use a known safe fallback when appropriate. Preserve evidence and maintain a clear timeline.

Assign an incident lead and communication owner. Avoid multiple people making conflicting production changes. Communicate what is known, what is uncertain, the user impact, and the next update time without speculative promises.

Apply the ideaDraft a short client update for a retrieval freshness incident.
Module 18 / Lesson 04

Recover and validate

Restore the service through a tested rollback, dependency recovery, or repaired data path. Verify user-facing behavior and access controls before declaring recovery. Check queued work and uncertain writes rather than assuming they resolved themselves.

Fallback behavior must have its own boundaries. Returning an old cached policy may be worse than temporarily refusing to answer. Choose fallbacks according to data sensitivity, freshness, and the task’s consequences.

Apply the ideaDefine a safe response during model outage and a different response during stale-policy detection.
Module 18 / Lesson 05

Learn from the incident

A postmortem explains the sequence, contributing factors, detection gaps, response, and follow-up actions. Avoid reducing the explanation to a person’s mistake when system design made the failure easy.

Assign owners and due dates to a small number of concrete improvements. Convert important failures into tests or monitoring. Review whether the original assumptions about workload, permissions, or dependencies still hold.

Apply the ideaWrite a postmortem with one prevention action and one detection improvement.

Worked scenario

An assistant continues answering from an index that missed a policy revocation. Contain by disabling affected answers or enforcing a safe freshness gate, then repair synchronization and invalidate caches. Recovery includes proving the revoked source is absent from future retrieval and citations.

Practical assignment

This is a practical design or implementation assignment. Use synthetic data. Where managed services are required, verify account access, costs, supported features, and cleanup before provisioning.
  1. Rehearse model outage, stale index, and denied tool action.
  2. Record a timeline and user impact.
  3. Choose containment and safe fallback.
  4. Verify recovery with explicit checks.
  5. Draft stakeholder communication.
  6. Create a postmortem and add a regression case.

Knowledge check

1. What should happen first during a harmful write incident?
2. Is stale cached policy always a safe fallback?
3. What makes a postmortem useful?

Answer guide
  1. Contain the unsafe behavior and assess impact. Containment reduces further harm while diagnosis continues.
  2. No. Freshness and task consequences determine whether fallback is acceptable.
  3. A causal explanation and owned improvements. Learning requires concrete prevention or detection changes.
