Final answer:
Andrea needs approval from the change advisory board or steering committee to upgrade the outdated OS on the company's servers. She should present the risks of not upgrading, like security vulnerabilities and compatibility issues, to convince them.
Step-by-step explanation:
When Andrea discovers that her company's servers are running an obsolete operating system (OS), she needs to prepare a plan to upgrade them.
According to company policy, before any work can commence, the upgrading process must be approved by those holding decision-making power within the company, commonly known as the change advisory board (CAB) or steering committee.
It is the responsibility of this group to assess the risks, benefits, and costs associated with the upgrade and decide whether to proceed.
Andrea must present a convincing case that highlights the importance of the upgrade, possibly emphasizing on the consequences of maintaining an unsupported OS, such as security vulnerabilities and incompatibility issues with modern software, which can lead to productivity loss and potential data breaches.
