Your Salesforce has multiple types of Cases that require different fields. How should your company support this business need?

A Page Layout alone controls field arrangement and visibility but cannot differentiate between different types of records or enforce different picklist values per type.

Record Types allow administrators to define different business processes, picklist values, and page layout assignments for different categories of records on the same object. By assigning different Page Layouts to each Record Type, each Case type can display its own relevant fields without creating redundant objects.

Creating another object adds unnecessary complexity and data model overhead - the Case object natively supports multiple types through Record Types.

A Workflow Rule automates post-save actions like email alerts or field updates and has no capability to control field display based on case type.
