Which group should be notified for approval when a planned modification to an environment is...

TheChange Management Board (CMB), also called the Change Advisory Board (CAB), is the formal authority responsible for reviewing, assessing, and approving planned modifications to IT environments. This group ensures that proposed changes align with business objectives, do not introduce unnecessary risks, and comply with security and regulatory requirements.

Event management teams focus on monitoring events, problem management teams handle root-cause analysis, and executive boards provide strategic direction but are not operational approval authorities. Only the CMB has the explicit role of validating technical and security implications before implementation.

By involving the CMB, organizations enforce structured governance, minimize disruptions, and establish accountability. This practice is central in ITIL and ISO/IEC 20000 standards, ensuring that operational integrity and security are preserved during change cycles.
