Which tool is used to configure decisions within Appian automation?

• A. Decision Tables
• B. Expressions
• C. Interfaces
• D. Process Models

Answer: (A)

Decision tables are the primary way to model decision logic in Appian automation. They present rules in a clear, tabular form where each row defines a specific combination of input conditions and the corresponding outcome. Appian evaluates the inputs against the table and returns the matching result, making it easy to update decisions without changing the process flow or writing code. This separation of decision rules from the process model improves readability and maintainability, especially for business users who need to adjust rules as requirements change. Expressions, interfaces, and process models play other roles—expressions for inline calculations, interfaces for user interaction, and process models for the overall flow—so they aren’t as well suited for configuring decision logic as a structured decision table.
