The Failure Modes Catalog

AI operations fail in predictable ways. The same seven failure modes show up across industries, company sizes, and use cases. Knowing them before they happen is the difference between a smooth operation and an expensive lesson.

Failure Mode 1: Data Drift

The data your AI was trained on or configured for no longer matches the data it receives. Customer behavior changed. Market conditions shifted. A data source started sending a different format. The system still runs but the output degrades silently.

Failure Mode 2: Prompt Rot

A prompt that worked six months ago produces worse results today because the underlying model updated, the business context changed, or edge cases accumulated that the original prompt did not handle. Prompts need regular review.

Failure Mode 3: Silent Failures

The operation completes without errors but the output is wrong. A lead scored at 90 should have been scored at 30. An email sent to the wrong segment. The system reports success because it ran to completion, but the result is incorrect.

Failure Mode 4: Dependency Collapse

A third-party API changes its format, raises its prices, or goes down. Your operation depends on it and has no fallback. One external change cascades through your entire system.

Failure Mode 5: Scope Creep

The operation was built for one use case but gradually got extended to handle more. Each extension adds complexity. Eventually the system is doing things it was never designed for, and the failure rate climbs.

Failure Mode 6: Knowledge Loss

The person who built the operation leaves. Documentation is incomplete. Nobody fully understands how it works. Maintenance becomes guesswork and changes introduce new bugs.

Failure Mode 7: Cost Escalation

Usage grows. API costs scale. What was $50 a month becomes $500 a month and nobody notices until the bill arrives.

The Prevention

For each failure mode, there is a simple countermeasure: monitoring for drift, scheduled prompt reviews, output validation, dependency fallbacks, scope documentation, thorough documentation, and cost alerts. None are complex. All require discipline.

The Prevention Protocol

Create a monitoring check for each failure mode. Data drift: compare this month's input distribution to last month's. Prompt rot: run a golden dataset through your prompts monthly. Silent failures: validate outputs against known-good examples weekly.

The seven failure modes in ai operations are predictable. Predictable means preventable. Build the monitoring before you experience the failure, and most of these modes become non-events instead of crises. The failure modes catalog is your prevention checklist, not just a list of things to worry about.
