The CAB handles various changes, from emergency reviews to routine upgrades, guiding organizations in making informed decisions. It helps reduce disruptions to IT services and applications and is crucial in change and IT service management across different industries. Typically, the CAB holds regular meetings, either weekly or biweekly, to review change requests.

How Does Change Advisory Board Work?

The change advisory board (CAB) is a critical component of business change management, primarily focused on assessing, aligning, and approving changes in an organization’s IT services, applications, infrastructure, and operations. It acts as an advisory body for the change manager, evaluating risks and potential consequences associated with change requests. The CAB gained prominence with the IT Infrastructure Library (ITIL) in the 2000s and has become an essential part of IT change management processes.

The change advisory board (CAB) operates through a structured process involving four key steps. First, when a department or team wishes to make a change, they submit a formal proposal to the CAB. Second, the CAB convenes a meeting to thoroughly examine the proposal, considering its potential benefits and associated risks. Additional information may be requested during this phase. Third, based on a comprehensive review of all pertinent information, the CAB decides to approve or reject the proposed change. Finally, if the change is approved, the CAB plays an essential role in guiding the efficient implementation of the change, ensuring a coordinated and well-executed process.

The CAB’s role is crucial in minimizing service disruptions, promoting accountability and transparency in decision-making, ensuring changes align with organizational goals, and achieving financial objectives through cost reduction, improved productivity, and increased revenue. For organizations, it finds utility in managing minor upgrades to significant transformations. The CAB should operate autonomously to be effective, and its members must collaborate to benefit the organization.

Roles And Responsibilities

The change advisory board (CAB) plays a critical role in reviewing and approving changes within an organization. Here are the key roles and responsibilities of CAB members:

  • Change Evaluation: CAB assesses change proposals, considering their impact on the organization by conducting risk assessments, weighing benefits, and evaluating feasibility.
  • Change Approval: Upon thorough evaluation, CAB can approve or disapprove change proposals.
  • Change Planning: CAB collaborates with stakeholders to develop comprehensive plans for implementing approved changes. This includes addressing potential disruptions, allocating resources, managing dependencies, and creating effective schedules for seamless transitions.
  • Risk Management: CAB conducts in-depth risk analysis for change implementations, covering compliance, security, and operational impact, to mitigate and manage potential risks effectively.
  • Communication and Coordination: Serving as a bridge between stakeholders, the change manager, change proposer, and implementation teams, CAB facilitates communication and ensures seamless coordination throughout the change process.
  • Change Documentation: CAB maintains accurate and up-to-date records of all approved and implemented changes, using a standardized change advisory board template for documentation.
  • Post-Implementation Review: After changes have been implemented, CAB conducts reviews to assess their impact on various operations. Feedback is collected to monitor performance and identify areas for further improvement, enhancing overall efficiency.


The composition of a CAB is vital to its effective functioning in change management. Here are the key members and their roles within the CAB:

  • Stakeholders’ Representatives: The CAB should include representatives from various departments and stakeholders to ensure a comprehensive perspective on proposed changes.
  • Subject Matter Experts (SMEs): SMEs contribute their specialized knowledge of change management and related domains, offering insights into risks, potential impacts, and technical aspects of transitions.
  • Change Managers: These individuals oversee and successfully implement changes, managing the entire process from planning to execution.
  • Change Initiators: Teams or individuals who propose changes play a pivotal role in the CAB. They provide essential information, answer queries, and explain the rationale behind their proposed changes.
  • Senior Management Representatives: Members from senior management teams bring leadership, resources, financial support, and strategic alignment to the change implementation process.
  • End-User Representatives: The presence of customers and employees who will directly experience the changes is crucial. They offer valuable insights into customer satisfaction, daily operations, and the user experience.

How To Set Up?

Setting up an organization’s change advisory board (CAB) requires careful planning and execution. Here’s how to establish a CAB effectively:

  • Define Objectives and Scope: Clearly define the CAB’s scope, objectives, and decision-making authority. This helps identify the types of changes it will handle and the responsibilities of members.
  • Identify Key Stakeholders: Identify and involve essential stakeholders participating in the CAB and contributing to decision-making.
  • Establish Meeting Frequency and Structure: Determine a suitable meeting frequency and structure for CAB sessions. Define the roles and responsibilities of members during these meetings.
  • Develop Change Evaluation Criteria: Create evaluation criteria, considering factors like impact, risks, alignment with business goals, and resource requirements to assess proposed changes.
  • Document Change Management Process: Document every stage of the change management process, from proposal submission to change implementation. Clearly outline the roles and responsibilities of CAB members at each stage.
  • Define Communication Channels: Establish effective communication channels for sharing information, collaborating on decisions, and providing feedback among CAB members.
  • Continual Improvement: Regularly review and improve the CAB’s performance based on member feedback and the outcomes of implemented changes.
