    What is Change Advisory Board (CAB) Approval?

    For any organization that has attained maturity, it is important to incorporate various changes into its software. Change, no matter how small, is always critical for a successful software product. For a business to perform essential business operations seamlessly, it must rely on software operating. They also have to count on software updates.

    What is Change Management?

    Changes in software can be as small as incorporating a small shiny feature to something as big as a security update, which is critical. Businesses must make sure that the latest changes in the features do not tamper with the existing infrastructure. This is the purpose of change management. It helps in ensuring that any update or change in software does not tamper with the existing functions.

    Change Management CAB refers to all the activities that are related to preparing, supporting, and assisting the individuals, teams, and the organization, to bring about a structured change in the organization. To have a better understanding of the concept, you can undergo an ITIL 4 Foundation Certification.

    What is the Change Advisory Board (CAB)?

    Change Advisory Board or CAB refers to a group of people who are entrusted with the task of monitoring and evaluating the changes that are incorporated in an IT environment. The business and its culture are responsible for assessing the level of appropriateness of a change that is being incorporated. Some of the IT Services certification courses will help you have a better insight into these topics.

    Now a question might arise in your mind about who makes up the Change Advisory Board. Well, the CAB consists of key people who are responsible for decision-making and technically skilled staff. There is no fixed rule about who can be a part of the Change Advisory Board. There is a Change Manager, who makes sure that the right people who have the right information, background, and knowledge are entrusted with the task of reviewing the changes made to an IT environment. Sometimes Subject Matter Experts are called in so that they can review the changes made and advise on them if required.

    The main task of the Change Advisory Board is to review the changes and make sure that they do not pose any threat or risk in the future, so as to avoid unwelcome consequences. What differentiates Change Advisory Board from Change Management is that Change Management refers to the entire process of raising, reviewing, monitoring, evaluating, and finally approving and tracking the changes to oversee the impact that it has brought about in the IT environment. However, CAB approval only means that the team approves (or disapproves) the changes that are to be incorporated into the IT environment.

    Change Advisory Board (CAB) Members

    There are several members who are involved in the Change Advisory Board. All these personalities work at diverse levels of the Change Advisory Board process flow and aid in the process of efficient Change Management.

    • Service Desk Analyst

    A Service Desk Analyst is assigned who takes the calls related to service, documents the incidents, and then escalates the matters to the Service Desk Manager. To put it in simpler words, the Service Desk Analyst helps to offer awareness regarding the issues that might arise with service delivery and helps to resolve them to ensure the smooth functioning of the IT environment.

    • Operations Managers

    The Change Advisory Board also consists of the Operations Managers, who are accountable for looking over the daily administrative activities of the organization.

    • Engineer or Application Manager

    The application Manager is responsible for looking over the development of the applications and their arrangement. To be suitable for this role, a professional has to have the ability to make quick and error-free judgments. He should also be knowledgeable about the ins and outs of all the products that are offered to the clients.

    • Information Security Officer

    As the name suggests, the Information Security Officer must take care of issues that are related to network security daily. He should also provide knowledge related to the possible threats or any susceptibilities that might be associated with any system or application.

    • Senior Networking Engineer

    The task of the Networking Administrators is to supervise the networks and cloud infrastructures of a company and manage them. This post holds considerable responsibility; therefore, it requires a Senior Networking Engineer to have certain years of experience.

    • Business Relationship Managers

    They are the ones who directly work with the clients in a B2B kind of setting. Nevertheless, they can also work on issues related to customer service. They are the ones who offer a deep insight into the needs and wants of the clients.

    These, along with other professionals of eminence, ease the CAB approval process and help to bring about the proper functioning of the IT environment of any organization. KnowledgeHut's Service Management training will help you better understand these topics.

    Functions of the Change Advisory Board

    Change Advisory Board (CAB) Operations

    Every managing body follows a certain course of action to be able to work properly. In the case of the Change Advisory Board, it is the Change Manager who oversees conducting timely meetings of the CAB, in which it discusses its agenda and course of action to be able to perform seamlessly. The meetings can either be conducted on a timely systematic basis or can be called based on the intensity of any matter that needs to be discussed and taken into consideration.  

    In case of a crisis where a meeting is to be called on an urgent basis, it has to be related to some incident that can threaten critical business tasks. However, it is only the Change Manager who has the right to take a final call on the change, even in case of emergencies.

    Challenges Facing the CAB

    No process continues in an error-free manner. Even the Change Advisory Board meets certain challenges during its action. Here are some of the common problems that the Change Advisory Board might come across: 

    1. It might be inefficient and slow: In case of an emergency change, CABs are not able to incorporate them on an urgent basis. They are a little slow and inefficient.  
    2. It might be difficult for CABs to track the project health throughout: In order to track the project health, it is important for CABs to track the health of the project, which might be a little difficult sometimes. 
    3. Incorrect planning might be an issue: In the case of Change Management and Change Advisory, incorrect planning may pose a massive threat. It is, therefore, of the utmost necessity to ensure that proper planning is done before the execution of every stage, followed by proper evaluation of the change incorporated.   
    4. Insufficient resourcing: Sometimes, experts may not be enthusiastic enough to deliver their best; therefore, insufficient resources might be another problem that needs to be dealt with to ensure the seamless functioning of the IT environment of a business or organization.  
    5. The change implementations may sometimes be partial: With the ITIL change management procedure, CAB may sometimes implement only a few parts of the changes to be incorporated while leaving behind some of the others. 

    Future of CAB

    CAB is a strategic change that has helped in automating the methods. This helps to free the attention and time of the leaders and managers so that they can focus more on the other strategic kind of work, which can be executed better with their involvement. 

    Therefore, it is no wonder that CABs are going to have a great demand in the future. The requirement for agility in the delivery of superior quality services and products is never-ending. Technology, if it goes wrong, can disappoint the clients. Therefore, companies need to invest in a robust Change Management system, of which the Change Advisory Board is an inseparable part.  

    However, owing to the kind of inefficiency that CAB exhibits, there might be some disadvantages. In the case of structures where digital organizations adopt structures that are more product-centric and the product life cycles are managed entirely by small teams, CAB may be irrelevant. Nevertheless, CAB might still be useful for huge organizations with a soiled structure.


    In a nutshell, we can say that CAB, or the Change Advisory Board best practices help in delivering support to the team of an organization that deals in change management. The team works by advising on the changes that have been proposed, assessing, and prioritizing the changes that are to be or have been incorporated. Therefore, CAB helps in offering a varied perspective for efficient decision-making. Hope this gives you an idea about the role of CAB and the importance of CAB approval in decision making.
