Which of the following would be used to communicate a high level description of a major change that involved significant cost and risk to the organization?

In ITIL change management, a change proposal is specifically created for significant or major changes that carry substantial cost and risk, providing decision-makers with a high-level overview before detailed planning begins. It differs from a request for change in that it is submitted earlier in the process to secure high-level approval and funding commitment, ensuring that only justified major changes proceed to full planning.

A change policy is a governance document that defines the rules and criteria for managing changes broadly, not a communication artifact for a specific change instance.

A service request covers routine, pre-approved, low-risk activities such as password resets or standard software installs, not high-cost major changes.

A risk register is a repository used to log and track risks across the organization and is not used to communicate the scope or description of an individual change.
