Milestones are time-dependent tasks that represent required steps in your support process, such as first response time or resolution time. By defining entitlements and milestones, you can ensure that each case goes through the set of steps required by your SLA and meets the time limits for each step.

You can use the Lightning App Builder to define criteria-based record page components for different objects and apps. Verified References: [Criteria- Based Record Page Components]
