For the requirement that a credit check must be completed for a credit card to be approved,

incorporating the credit check as part of the credit card application process is necessary. The most

straightforward way to model this is by using case type relationships.

C . Make credit check a child case of credit card request: This configuration establishes the credit

check as an integral step within the credit card request process, ensuring that the credit check is

completed before the credit card can be approved. Making the credit check a child case means it is

directly associated with and dependent on the parent credit card request case, aligning perfectly

with the requirement.

Making both the loan request and credit check top cases (A) does not establish the necessary

dependency. Creating a spin-off case (B) suggests a parallel or subsequent process not inherently

dependent on the completion of the credit check for the credit card request, which could misalign

with the requirement. Making the credit card request a child case of credit check (D) inverts the

intended relationship and does not accurately represent the process flow described in the

requirement.

Reference: Pega's case management documentation provides insights into designing case hierarchies

and relationships, including the use of child cases to model dependent processes within an

overarching case.
