Certified Pega Decisioning Consultant (CPDC) Practice Exam

When implementing a decisioning project, establishing an issue and group hierarchy is crucial as it lays the foundational structure for the entire project. This hierarchy helps categorize and organize the different decisioning scenarios and propositions that will eventually be used. By defining the issues first, you can effectively group them in a logical manner that aligns with business objectives and customer needs.

Having a clear issue and group hierarchy allows subsequent steps, such as defining prioritization rules and determining which propositions to use, to be more coherent and focused. It ensures that all decisions made in later phases are aligned with the overarching strategy and goals of the project. Thus, it's essential to start with this foundational element to guide and inform all following decision-making processes.

Other steps, like defining prioritization rules or propositions, can only be effectively executed if there's a structure in place that describes how issues are categorized and prioritized based on business importance or complexity.
