• C. A method to plan marketing campaigns
• D. A formal process to assess, approve, and implement changes; reduces risk, maintains service quality, and ensures traceability

Answer: (D)

Change management in IT is a formal process to assess, approve, and implement changes to the IT environment. By evaluating the potential impact, risks, and dependencies before any modification, it helps prevent unintended side effects that could disrupt services. Approved changes are scheduled, implemented with a rollback plan, and tested, with all steps and rationale documented to create a clear record of what happened and why. This traceability is crucial for accountability and audits. The process also standardizes how changes are made, reducing variability and the likelihood that unauthorized or conflicting modifications will occur. For successful IT services, this means fewer outages, more consistent performance, and the ability to meet service levels. Even emergency changes can be handled within a controlled framework to restore service quickly while still maintaining documentation and post-change review.
