Explanation: Release management involves planning, coordinating, executing, and validating changes and rollouts to the production environment. Change management is a higher-level component than release management and also involves stakeholder and management approval, rather than specifically focusing the actual release itself. Availability management is focused on making sure system resources, processes, personnel, and toolsets are properly allocated and secured to meet SLA requirements. Problem management is focused on identifying and mitigating known problems and deficiencies before they occur.
