The first step is to document the change request with all relevant details, including the reason for the change, its potential impact, urgency, and associated risks. Once documented, the change is assessed for feasibility and business impact. Each change request is prioritized and scheduled based on its classification—normal, emergency, or standard. After review by the Change Advisory Board (CAB), the change is either approved, rejected, or deferred. Upon approval, it is implemented under controlled conditions and monitored for any adverse effects. Finally, a post-implementation review ensures that the change delivers the intended results and identifies areas for improvement. This methodical progression ensures that change implementation does not disrupt ongoing services or deviate from the organization's strategic goals.
