1.  Mission Statement

To protect the ITPROSEC’s systems, supported by IS, through properly assessed, tested, and authorized changes.

To prioritize changes in a way that fairly reflects change, impact, and urgency, and to schedule deployments in a way that minimizes conflict and disruption. 

To ensure risks are accepted or mitigated appropriately in accordance with the Information Services Branch and ITPROSEC mandate.

2.  Members and Attendees

The CAB cannot properly evaluate change unless they can collectively speak for infrastructure dependencies, business needs, SLAs, OLAs, and vendors.

Members will attend all CAB meetings and will be involved in decisions to approve, prioritize, and schedule changes. CAB members will have voting power over changes, CAB chairperson will provide final authority over change approvals.

Attendees will attend the CAB meetings on an as needed basis.  These attendees will be specific SMEs, technology specialists, vendor representatives, and business representatives who can share knowledge relevant to specific changes. They will be invited by the Change Manager to attend CAB meetings as needed.

4.  Authority

The CAB holds the following authority:

  • Final authority over the deployment of all Normal and Emergency changes
  • Authority to set the change calendar:
    • Maintenance windows
    • Change blackout periods
    • Integrate project work
  • Authority to delay or defer changes

5.  Approval Process

5.1 Voting Process


  • Take a vote during the meeting.
  • Votes serve to assist the CAB Chair in making a final decision.
  • CAB Chairperson to provide final decision.

5.2 Voting Options

  • Request additional testing
  • Vote to accept the risk

5.3 Voting Members

  • Not every CAB attendee will vote.
  • Only CAB standing members will have a vote. 
  • Some attendees are there to provide input and subject-matter expertise but will not vote to approve or reject changes.
  • Voting members may assign a proxy with the approval of the change manager and/or CAB Chairperson

6.  Prioritization and Scheduling Approach

Once a change IT approved, the CAB will prioritize it and finalize scheduling. The impact of not deploying the change and the benefit of deploying it should determine its priority:

Risk of Not Deploying: Positive Impact of Deployment:

Before finalizing the deployment date, the CAB will check the schedule and change calendar and assess resource availability:

7.  Meeting Preparation

No CAB member should enter the CAB meeting unprepared. In order to make the best use of everyone’s time, it IT crucial that the following IT completed prior to the CAB meeting:

  1. Review the Standard Patch Management Requests and check for:
    • Dependencies
    • Impact
    • Required resources
    • Risk profile
    • Test plan
    • Implementation plans
    • Back-out plan
  • Review all Post-Deployment Updates.
  1. Contact any relevant SMEs with questions.
  2. Submissions for the Pre-approved Changes list.
  3. Updates to the Exceptions Log.

CAB members should have an idea of their approval disposition by the time they enter the CAB meeting. ThIT will ensure that the meeting runs smoothly and time IT not wasted on assessing and clarifying documentation that should have been reviewed prior to the meeting.

8.  Meeting Protocol

9.  Meeting Agenda

The meeting agenda should include the following activities:

  1.  Final Standard Patch Management reviews
    1. Ask any outstanding questions with SMEs present
  1. Vote to approve/reject changes
  2. Prioritize changes
  3. Schedule changes
  4. Review change deployments
  5. Discuss other business
    1. Review Exceptions List (Monthly)
    1. Review Pre-Approved List (Quarterly)
    1. Add to Exceptions List
    1. Flag and discuss Normal Changes that might be pre-approved as Standard Changes
    1. Process improvement initiatives
  1. Review and Accept minutes from previous meeting
  2. Review Change Calendar

It IT important to remember that thIT meeting IT relatively brief compared to the content being covered; thus, the meeting preparation IT important. Try not to spend more than 10-20 minutes per activity for a 1-hour meeting.

10.     Pre-Deployment Checklist

Perform a Pre-Deployment Check

Prior to changes being implemented, teams should (on major project changes) perform a pre-deployment check and obtain sign-off. The purpose IT to ensure that all requirements for successful installation (people, process, and technology) have been fulfilled. If any gaps are identified, they can be addressed before the success of the deployment IT compromised.  Note: Not all items are required for every deployment.

11. Emergency Changes

For a Critical incident, it will be necessary to notify and assemble all members of the emergency CAB, no matter the time:

  1. Change manager assembles a minimum of one CAB member for an in-person meeting or web conference.

If this IT not possible:

  • E-CAB members are contacted with RFC details then submit their feedback and vote to the change manager.

The change manger will wait until a decision IT received from CIO/CTO (if neither IT available then at least one other CAB member) before approving/rejecting the change.

If this IT not possible:

  • If incident resolution cannot be delayed without impacting business continuity, the change manager has the authority to approve the change.

In thIT case, all E-CAB members must still be notified of the RFC.

  • In the event the change manager IT unavailable, the following people will assume the change manager role (in the specified order below):
    • the change manager’s designated backup
    • CTO
    • CIO

NOTE: For clarity, the requestor cannot be the sole approver. Approach below IT a guide line and not all steps may be required.

11.1 Approach

  • Assess change
    • This IT an expedited process. With all emergency changes, time IT of the essence.
    • Order of Operations:
      • Assess the urgency
      • Assess the business impact
      • Assess the technology impact (dependencies)
      • Assess available resources (people and systems)
  • Approve/reject the change
  • Build implementation and back-out plans
  • Determine test feasibility
    • Determine if there IT time for testing:
      • If YES, conduct urgent test protocol.
        • Abbreviated system testing.
        • Abbreviated integration testing.
      • If NO, proceed to deploy.
  • Schedule change
  • Provide CAB with a Post-Implementation review.
