## Meaning

A group of senior people from different departments who review and approve proposed changes to systems or software before they are implemented. This board ensures changes do not cause problems for the business or users.

A change advisory board (CAB) is a governance mechanism used in IT service management and software development to control and manage change risk. The board typically includes representatives from operations, development, quality assurance, product management, and business stakeholders. Before major changes are released to production, the CAB reviews the change request, assesses potential impact on existing systems and users, and decides whether to approve, defer, or reject it. This prevents unplanned outages and ensures alignment between technical changes and business needs. In larger organizations, the CAB meets regularly (weekly or bi-weekly) to triage pending changes, while smaller teams may use an ad-hoc approach. The board uses tools like change impact assessments, rollback plans, and testing results to make informed decisions.

## When you hear it

The change advisory board must approve all database schema changes before deployment to production.

## Examples

- **in a standup:** "We have submitted the authentication module update to the change advisory board for review next Thursday."
- **in a code review:** "This is a breaking API change, so we need to document it well for the change advisory board presentation."
- **in a team meeting:** "The change advisory board has asked us to provide a detailed rollback plan before they will approve the infrastructure migration."

## What native speakers say

- "The CAB approved our deployment request"
- "We need to present this to the change advisory board"
- "The change advisory board rejected the proposal due to risk concerns"

## Common mistakes

- ✗ "We made a change advisory board to handle the bug fix." → ✓ "We submitted the bug fix to the change advisory board for approval." (The board does not make changes; it reviews and approves changes that have been proposed by teams.)
- ✗ "The change advisory board is only for database updates." → ✓ "The change advisory board reviews all significant changes, including infrastructure, application, and configuration updates." (A CAB evaluates any change that could impact the system, users, or business, not just specific types of changes.)
- ✗ "We do not need the change advisory board for small patches." → ✓ "We should follow our change policy to determine if this patch requires change advisory board approval." (Whether a change needs CAB review depends on organizational policy and the change's risk level, not just its size.)

## Be careful

Often abbreviated as CAB but this can confuse people unfamiliar with the acronym. Do not confuse with general advisory boards used in other industries.
