The short answer

Recommendation
Make the use safe first, then decide whether it can go on. Stop a never-allowed practice or special category data at once; screen an AI feature a supplier added as a running use under dated conditions; stop any other unapproved tool within the policy's working days and move people to one they may use.
Reasoning
Finding an unapproved use means the procedure is working. The aim is to limit exposure while you find the facts, so people are asked to put nothing above Public in, and no personal data, before anything else. A threat of penalty makes people hide what they do, so reports made in good faith carry no blame. The incident pack, not this flow, decides whether data that went in is an incident. A stop works only with an alternative: people who have an approved tool stop using the free one.
Considerations
  • The figures are the pack's defaults: an unapproved tool stopped within 3 working days of discovery (AG-02), and a running Tier 2 or 3 use assessed within 90 calendar days of the inventory closing.
  • A prohibited practice or special category data gets no dated condition. Tell Legal or the Data Protection Officer the same day.
  • Carrying on after being told to stop, putting Confidential information into a personal or free account, or hiding a use may be a conduct matter under your disciplinary procedure. Keep it apart from the no-blame report.
  • Without an approved list, every tool counts as unapproved.

The same flow written out: each step, its reasoning and where the pack covers it. 20 steps.
  1. Start

    We find staff using AI tools nobody approved

    Finding one means the procedure is working. Most organisations find AI uses they did not know about: a free assistant on personal accounts, a feature a supplier added in a release, or a tool a team bought with a card. The aim is to make the use safe first and then decide whether it can go on. Do not email everyone to ask who uses AI and threaten a penalty, because people hide what they do.

  2. Step

    Tell the AI governance lead the same day

    Whoever finds the use tells the lead, whatever the source: the inventory survey, discovery of systems bought with a card or signed into with a work address, a supplier's notice of a new AI feature, a manager's question or a staff report. In the pack's example the staff survey found the free assistant on personal accounts. The lead owns the steps that follow.

  3. Decision

    Never-allowed practice or special category data, as far as you know?

    These two cases skip the working days the policy otherwise allows. A use that matches a prohibited practice, or that takes special category personal data, stops now. Tell Legal the same day for a prohibited practice. For special category data report at once and tell the Data Protection Officer the same day. Legal decides whether a use matches and whether anything further is needed. Judgement: if you are unsure, answer yes. The questions that follow check again.

    In the pack

  4. Outcome

    Stop it now and tell Legal or the DPO the same day

    Do not wait for the working days the policy sets, and set no dated condition. Tell Legal the same day for a prohibited practice. For special category data, report it at once as an event through the incident route and tell the Data Protection Officer the same day. Nobody is blamed for a report made in good faith, and the incident pack decides whether it is an incident and what must be reported.

    In the pack

  5. Step

    Ask people to put nothing above Public, and no personal data, in

    Do this first, before you work out the rest. It limits the exposure while you find the facts. Say plainly that nobody is blamed for a report made in good faith, because people who feel blamed hide the use. Public information with no personal data in it stays allowed in any tool, but never through a work account. Personal data needs a tool approved for it, even inside Public information (BC-5).

    In the pack

  6. Step

    Ask what went in, over what period, through which account

    Compare the answers with the approved list. The questions are about data level, not fault. Ask what was pasted (draft text, customer material, code, personal data), over what period, and whether the account was a personal or a work one. In the pack's example the four users confirmed the same day that no personal data and no Confidential files had gone in.

    In the pack

  7. Decision

    Do the answers show special category data or a never-allowed use?

    The users' answers can show what the first look did not. If special category data went in, or the use matches a prohibited practice, treat it as a stop now. Judgement: if the users cannot say what went in, answer yes.

    In the pack

  8. Decision

    Did Internal, Confidential or personal data go in?

    Internal or Confidential information that went into a tool not approved for it is reported as an event, and so is personal data that went into a tool not approved for it, even inside information that is otherwise Public (BC-5). Judgement: if the users cannot say what went in, answer yes. Public information with no personal data in it goes in under the Public rule, not as mishandling.

    In the pack

  9. Step

    Report it as an event through the incident route

    This is an event report. The incident pack screens every report and decides whether it becomes an incident and whether any reporting duty and clock applies, so set no clock here. In the pack's example the free assistant held only draft campaign wording (Internal). Triage found no incident the same day and no reporting duty arose.

    In the pack

  10. Decision

    Is it an AI feature a supplier added to software we already use?

    Suppliers add AI features in releases. The pack treats the feature as a new use and screens it. If it is already switched on, it is a use found running, and a missing supplier decision becomes a dated condition, as it did for the pack's warehouse forecasting module. A separate AI tool, or a free assistant, is a different case: answer no. Notice of a new AI feature is supplier term ST-7, which P06 clause CL-20 carries.

    In the pack

  11. Step

    Screen it as a new use, marked already running

    Answer the twelve intake questions as the use runs today and mark it as already running. The screen sets the tier as for a new use, taking the highest tier any trigger gives. A hold that would stop a new use becomes a condition with a date, because stopping a service people rely on may do more harm than carrying on for a short time under control.

    In the pack

  12. Decision

    Does the screen set Tier 2 or Tier 3?

    Tier 2 applies when Confidential or personal data go in, customers or the public see the output, the use informs a decision about a person, or a wrong output would affect a core service. Tier 3 applies when the use falls in an Annex III area, decides or shapes a decision about a person, or acts on its own. Legal confirms any Annex III or role question. A provider signal, such as a feature built on a supplier's model API, does not raise a running use to Tier 3. H-4 becomes a dated condition until Legal records the role. A deployer role clears it and the answers set the tier. A provider or other role clears it but the use is then Tier 3, outside the pack's deployer governance. Else Tier 1.

    In the pack

  13. Outcome

    Approve with dated conditions, or stop it with a reason

    The tier's approvers approve with conditions (the executive decision-maker for Tier 3), or the use is recorded as Stopped with its reason. The use owner is consulted and signs the conditions it accepts, and nobody approves a use they own (IS-4). Write each condition with a date and the person who answers for it, and say in the decision that the tool is switched off if a date is missed. The assessment is due within 90 calendar days of the inventory closing by default, and the date goes in the inventory. Judgement: if that date has passed when you find the use, the approvers set a new date. The pack does not say.

    In the pack

  14. Outcome

    Decide: approve with conditions, or stop it with a reason

    The AI governance lead decides a Tier 1 use, by default within 5 working days of a complete request (the pack's example took 4). If the lead owns the use, the executive decision-maker decides in the lead's place (RS-16). If it goes on, enter the use, tier, approver, conditions and review date in the inventory, and add the tool to the approved list. Tier 1 is reviewed at 12 months by default. If it cannot go on, record it as Stopped with its reason.

    In the pack

  15. Step

    Stop the use within 3 working days and help people move

    A tool that is not on the approved list, or a use that needs data above what the list allows, is stopped within the working days the policy sets, 3 by default. The help matters as much as the stop: people who have an approved tool stop using the free one. Ask what they would need from an approved tool.

    In the pack

  16. Decision

    Do people carry on after being told to stop?

    Nobody is disciplined for a mistake reported at once. The policy says deliberately using an unapproved tool after being told to stop, putting Confidential information into a personal or free account, hiding a use, or putting special category data into any tool may lead to action under the disciplinary procedure.

    In the pack

  17. Outcome

    Take it to the line manager and HR as a conduct matter

    This is a conduct matter for the person's manager and HR, under the disciplinary procedure the policy names. Judgement: pass on the dates the person was told, and keep it apart from the no-blame reporting of the original event, so that reporting stays safe for everyone else. The pack does not set either step.

    In the pack

  18. Decision

    Does an approved tool already meet the need?

    Compare what the users wanted with the approved list. In the pack's example the four users moved to the approved assistant and finished the AI essentials module by 28 Sep, a week after the stop. If the list has nothing that meets the need, or you do not know, answer no.

    In the pack

  19. Outcome

    Move people to the approved tool and count the stop

    Move the users. The policy's evidence for a stop is the date found, the date stopped and the tool they moved to. Count it in the measure of unapproved uses found and stopped in time, such as 1 of 1, with any gap named, and never as a score.

    In the pack

  20. Outcome

    Propose the tool they need through intake

    If no approved tool meets the need, the use owner proposes one through intake. Ask what they would need from an approved tool, then approve one. Judgement: refusing without an alternative is likely to send the use back to personal accounts. Until a decision is made, only Public information goes in, and never through a work account.

Practical checklist

  1. Tell the AI governance lead the same day.
  2. Stop a never-allowed practice or special category data now, and tell Legal or the Data Protection Officer the same day.
  3. Ask people to put nothing above Public, and no personal data, into the tool.
  4. Ask what went in, over what period and through which account, and compare it with the approved list.
  5. Report any Internal, Confidential or personal data that went in as an event through the incident route.
  6. Screen a supplier-added AI feature as a new use marked already running, with each hold as a dated condition.
  7. Stop any other unapproved tool within the policy's working days.
  8. Move people to an approved tool that meets the need, or propose one through intake.

Evidence to have ready

  • For each unapproved use: the date found, the date stopped and the tool people moved to.
  • The users' answers on what went in, over what period and through which account.
  • The event report and the incident triage outcome for any data above Public.
  • For a running feature, the screen, the tier and each dated condition with its owner.
  • The monthly count of unapproved uses found and how many were stopped in time.

Assumptions

  • You have, or are setting up, an AI policy with an approved list and an AI governance lead. Without a list, every tool counts as unapproved.
  • The figures shown, 3 working days to stop and 90 calendar days to assess, are the pack's defaults. Your own policy may set different ones.
  • The people involved acted in good faith. Deliberate concealment or carrying on after a stop is a conduct matter and follows your disciplinary procedure.
