AIGO — AI Governance Operating Framework

AI Retirement Procedure

Version: 0.1
Status: Draft
Working Name: AIGO
Full Name: AI Governance Operating Framework
Document Identifier: AIGO-PROC-012

1. Purpose

This procedure defines the process for planning, approving, executing, documenting, and verifying the retirement of AI systems. The procedure ensures that AI systems are removed from operational use in a controlled manner and that associated risks, data, dependencies, access, controls, records, and obligations are appropriately addressed.

2. Scope

This procedure applies to the retirement of AI systems within the organization’s AIGO governance scope. It may apply to:
  • AI models;
  • AI applications;
  • generative AI systems;
  • AI agents;
  • AI-enabled business processes;
  • AI services;
  • third-party AI services;
  • AI infrastructure;
  • datasets and data pipelines; and
  • supporting governance mechanisms.

3. Objectives

The objectives of AI retirement are to:
  • ensure retirement is authorized;
  • prevent unintended continued operation;
  • manage transition risks;
  • protect data;
  • revoke unnecessary access;
  • manage dependencies;
  • preserve required records;
  • address residual risks;
  • meet applicable obligations; and
  • formally confirm retirement.

4. Retirement Principles

AI retirement should be:
  • planned;
  • authorized;
  • controlled;
  • documented;
  • traceable;
  • risk-based;
  • proportionate;
  • reversible where appropriate; and
  • verified.
Retirement should not be considered complete solely because a system has been removed from a production interface.

5. Retirement Triggers

An AI system may be considered for retirement when:
  • its intended purpose is no longer required;
  • a replacement system is available;
  • the system is obsolete;
  • risk has become unacceptable;
  • performance is no longer adequate;
  • the supporting technology is no longer available;
  • a supplier service is being discontinued;
  • regulatory requirements change;
  • the system is no longer economically viable; or
  • governance requirements cannot reasonably be maintained.

6. Retirement Request

A retirement request should identify:
  • AI system;
  • system owner;
  • reason for retirement;
  • proposed retirement date;
  • dependencies;
  • affected stakeholders;
  • replacement arrangements;
  • risk considerations;
  • data considerations;
  • contractual obligations; and
  • required approvals.

7. Retirement Assessment

Before retirement, the organization should assess:
  • operational impact;
  • business continuity;
  • security;
  • privacy;
  • legal and regulatory requirements;
  • contractual obligations;
  • data retention;
  • records;
  • dependencies;
  • user impact;
  • risk; and
  • replacement arrangements.

8. Retirement Classification

The retirement process should be proportionate to the significance of the AI system. Factors may include:
  • system criticality;
  • risk classification;
  • number of users;
  • affected stakeholders;
  • regulatory significance;
  • autonomy;
  • data sensitivity;
  • third-party dependencies; and
  • business impact.

9. Retirement Approval

Retirement should receive approval from an appropriately authorized authority. Approval may involve:
  • AI system owner;
  • business owner;
  • AI governance;
  • risk management;
  • security;
  • privacy;
  • legal;
  • compliance; and
  • executive management.

10. Retirement Plan

A retirement plan should be established for material systems. The plan should identify:
  • activities;
  • responsibilities;
  • dependencies;
  • timeline;
  • communication;
  • transition;
  • data handling;
  • access removal;
  • system shutdown;
  • validation; and
  • closure.

11. Stakeholder Identification

Relevant stakeholders should be identified before retirement. Stakeholders may include:
  • users;

13. Replacement Systems

Where an AI system is being replaced, the organization should assess the replacement system separately according to applicable AIGO requirements. Retirement approval should not automatically constitute approval of the replacement system.

14. Transition Planning

Transition should be planned where operational continuity is required. Transition arrangements may include:
  • replacement AI system;
  • alternative technology;
  • manual process;
  • temporary service;
  • phased migration; or
  • controlled service reduction.

15. Dependency Assessment

Dependencies should be identified before retirement. Dependencies may include:
  • applications;
  • APIs;
  • datasets;
  • models;
  • infrastructure;
  • workflows;
  • suppliers;
  • monitoring;
  • controls; and
  • human processes.

16. Dependency Removal

Dependencies that are no longer required should be safely removed or disabled. The organization should verify that removal does not unintentionally affect other systems.

17. Data Assessment

Data associated with the AI system should be assessed before retirement. The assessment should consider:
  • data ownership;
  • retention requirements;
  • legal obligations;
  • contractual requirements;
  • business records;
  • personal data;
  • sensitive data; and
  • deletion requirements.

18. Data Retention

Required records and data should be retained according to applicable requirements. Retention should distinguish between:
  • records that must be retained;
  • data that may be retained;
  • data that should be deleted; and
  • data that should be securely archived.

19. Data Deletion

Where deletion is required, it should be performed using appropriate methods. Deletion should consider:
  • production data;
  • backups;
  • replicas;
  • caches;
  • logs;
  • exported data;
  • third-party copies; and
  • derived data.

20. Personal Data

Where personal data is involved, retirement should include an appropriate privacy assessment. The organization should determine:
  • what personal data remains;
  • retention requirements;
  • deletion requirements;
  • access requirements;
  • archival requirements; and
  • third-party obligations.

21. Security Assessment

Before retirement, security requirements should be reviewed. The assessment may include:
  • credentials;
  • accounts;
  • service identities;
  • keys;
  • certificates;
  • network access;
  • integrations;

  • retention requirements.

25. AI Agent Retirement

Where an AI agent is retired, the organization should verify that:
  • autonomous execution is disabled;
  • tool access is removed;
  • credentials are revoked;
  • scheduled actions are disabled;
  • integrations are removed; and
  • outstanding tasks are resolved.

26. Third-Party Service Retirement

Where a third-party AI service is retired, the organization should address:
  • service termination;
  • contractual requirements;
  • data return;
  • data deletion;
  • account closure;
  • credential revocation;
  • integration removal; and
  • evidence of provider actions where required.

27. Monitoring Changes

Monitoring requirements should be updated when the system is retired. The organization should ensure that:
  • obsolete alerts are removed;
  • monitoring dependencies are removed;
  • required historical records are preserved; and
  • monitoring coverage remains appropriate for replacement systems.

28. Control Changes

Controls associated exclusively with the retired system should be reviewed. Controls should be:
  • retired;

The risk assessment should be reviewed before retirement. The review should consider:
  • retirement risks;
  • transition risks;
  • residual risks;
  • data risks;
  • security risks;
  • privacy risks;
  • continuity risks; and
  • replacement risks.

30. Risk Closure

Risks that exist only because of the retired system may be closed when sufficient evidence confirms that the underlying exposure no longer exists. Risks transferred to another system or process should remain open and be reassigned appropriately.

31. Incident Review

Open incidents involving the AI system should be reviewed before retirement. The organization should determine whether incidents:
  • must be resolved before retirement;
  • can be transferred;
  • require continued investigation; or
  • require retention of evidence.

Retirement should consider applicable:
  • laws;
  • regulations;
  • regulatory reporting;
  • contractual obligations;
  • litigation holds;
  • investigations;
  • records requirements; and
  • other legal obligations.

33. Records Management

Governance records should be retained according to applicable requirements. Records may include:
  • system profile;
  • risk assessments;
  • approvals;
  • change records;
  • monitoring records;
  • incidents;
  • assurance reports;
  • audit evidence;
  • contracts; and
  • retirement evidence.

34. Retirement Testing

Before final shutdown, appropriate testing should confirm that:
  • dependencies have been identified;
  • transition is functional;
  • required data has been handled;
  • access has been reviewed;
  • integrations are understood; and
  • shutdown will not create unacceptable impact.

35. Shutdown

The system should be shut down according to the approved retirement plan. Shutdown may involve:
  • disabling access;
  • disabling deployment;
  • stopping services;
  • removing integrations;
  • disabling scheduled tasks;
  • decommissioning infrastructure; and
  • removing unnecessary credentials.

36. Retirement Validation
