Page layouts, record types, and support processes are features that can be implemented to support different case management steps and fields for two separate business operations. Page layouts control the layout and organization of fields, buttons, related lists, and other components on a record detail or edit page. Record types allow you to offer different business processes, picklist values, and page layouts to different users based on their profiles. Support processes define the picklist values for the Status field on cases for each record type.
