AI risk appetite

The board or equivalent has approved a statement of how much AI risk the organisation will accept, broken down by kind of risk, and it is used in decisions.

Why it matters

Without a stated appetite, each approver applies their own tolerance, so similar uses get different answers and nobody can say whether the organisation is taking too much risk or too little. A board-approved appetite gives approvers a common reference and makes risk acceptance a deliberate choice.

Levels
0 AbsentConfirmed absent: the evidence shows nothing is in place. Not known is recorded as insufficient evidence, not 0.
1 InitialNo statement of AI risk appetite; tolerance depends on whoever is deciding.
2 DevelopingAI is mentioned in the general risk appetite, or a draft AI statement exists, but it does not distinguish kinds of risk or is not approved.
3 DefinedA board-approved, owned AI risk appetite sets tolerances by kind of risk, has a review date and is referred to in approval decisions.
4 ManagedExposure across live and proposed uses is reported against the appetite, and decisions that exceed it are escalated and recorded.
5 OptimisingThe appetite is recalibrated from evidence of outcomes, incidents and external change, and the board reviews whether it is enabling the intended use of AI.
Level 3 criteria

Level 3 is met when every applicable criterion is met. Criteria marked with an overlay apply only to organisations with that characteristic (overlays).

  1. RSK-01.1 A board-approved AI risk appetite sets a tolerance for each relevant kind of risk, such as harm to people, legal, reputational and operational risk.
  2. RSK-01.2 The AI risk appetite has a named owner and a review date.
  3. RSK-01.3 Approval decisions on uses of AI refer to the risk appetite.
Assessment questions
  • Has the board approved a statement of how much AI risk the organisation will accept?
  • Does it set different tolerances for different kinds of risk?
  • How do approvers use it when deciding whether a use of AI can go ahead?
Evidence an assessor would expect
  • The approved AI risk appetite statement, with approval record and review date
  • Approval records for uses of AI that refer to the appetite
  • Risk reports comparing exposure with the appetite
How to reach Level 3
  1. Agree the kinds of AI risk that matter to the organisation, for example harm to people, legal, reputational and operational.
  2. For each kind, write a tolerance statement saying what level of risk is acceptable, using the organisation's existing risk scale where possible.
  3. Name an owner and review date, and get the appetite approved by the board or equivalent.
  4. Add a reference to the appetite in AI approval templates so approvers must state how each decision fits it (see GOV-03).

Common pitfalls

  • Writing one overall tolerance that does not separate different kinds of risk.
  • Approving the appetite but never citing it in actual decisions.

Starter artefacts

  • AI risk appetite statement by kind of risk
