In Appian, which design object is primarily used to model and capture business rules?

• A. Decision Object
• B. Process Model
• C. Record Type
• D. Interface

Answer: (A)

Modeling and capturing business rules is best done with a Decision Object. This design object is built to house the rule logic itself—often expressed as decision tables or decision expressions—so you can define, test, and reuse rules independent of the process flow or UI. By centralizing rules in a Decision Object, logic such as eligibility, scoring, or policy decisions becomes a single source of truth that can be invoked from processes, interfaces, and other app parts, making changes easier and more consistent.

The other design objects serve different roles: a Process Model outlines the sequence of steps and tasks in a workflow, a Record Type defines the data structure for storing and retrieving data, and an Interface governs user interactions. While they may rely on rule results, they are not primarily designed to model and capture business rules themselves.
