QUESTION 2

With Pega’s Situational Layer CakeTM approach, how do you configure a regional variation for Human Resources (HR) time off cases?

  1. Create a rule for the variation and add the rule to the common layer of the application.
  2. Create a rule for the variation and add it to a secondary common application layer.
  3. Create a rule for the variation and add the rule to the layer for the region.
  4. Create a rule for the variation and replace the existing HR time off rule in the application common layer.

Answer: 3

I am confused with 2 and 3, can you tell me which one is the proper answer.

2

The correct approach is to create a rule for the regional variation and place it in the layer that represents that specific region. In Pega’s Situational Layer Cake, regional differences are handled by using a dedicated layer above the common enterprise or application layer. The base HR time off case stays in the common layer and remains unchanged. Any regional customization should be added in the regional layer so it only applies when that region is in context. This keeps the base application clean while allowing localized behavior where needed. So the right answer is to add the rule in the layer for the region.
