Hi  @HimanshiArora

Case Specialization in Pega is a design pattern used to define multiple variations of a case type based on specific conditions (like customer type, region, or product type). Instead of creating completely separate case types, you specialize one base case type into multiple versions that handle unique behaviors, rules, or processes.

• Tailored functionality: Adapt case behavior to address specific requirements for different regions, customer types, or product variations.
• Reduced complexity: Avoid creating a multitude of separate case types, simplifying development and maintenance.
• Enhanced flexibility: Easily adjust to changing business needs by modifying specialized rules without impacting the core case logic.

1. Class specialization: Create new classes that inherit properties and methods from existing case type classes. This provides the most flexibility for tailoring security, persistence, and rule resolution.
   • Pattern inheritance: Extend case type classes based on organizational structure (e.g., ORG-DIV-APP-Work) to accommodate variations across business units or regions.
   • Direct inheritance: Define specialized case types that directly inherit from a base case type, allowing specific rules and functionality to be overridden for that specialized case.
2. Ruleset specialization: Utilize rulesets to organize and manage specialized rules for different regions or functionalities. Pega's localization feature leverages ruleset specialization to display language-specific field values based on user locale.
3. Circumstance specialization: Create variations of rules based on specific conditions or properties (e.g., customer credit score, geographic region). This enables dynamic adaptation of case behavior at runtime without altering the core logic.
4. Application specialization: Build separate implementation applications on top of a common framework application to accommodate significant differences in business processes or user groups.
