LLM Model-Risk Register

A spreadsheet register of LLM failure modes per feature, scored by likelihood and impact, with controls and owners.

What's inside

  • A register sheet with one row per feature and failure mode: model, likelihood, impact, controls, owner, review date, status and open actions.
  • The risk score calculates as likelihood times impact.
  • A scoring guide with 1-to-5 likelihood and impact scales, each level with an LLM example, and the score bands for low to critical.
  • A sample register with ten rows across six features, covering failure modes such as hallucination, PII leakage, prompt injection and bias.

Format: Excel workbook.

How to use it

Add a row for each LLM feature before it launches and review the high scores on the date set in the register.
