Which design object captures complex, business-specific logic in an easy-to-read format?

• A. Interfaces
• B. Decisions
• C. Process models
• D. Expressions

Answer: (B)

Decisions are designed to capture complex, business-specific logic in a format that’s easy for non-technical stakeholders to read and adjust. In Appian, a decision design object organizes rules into readable structures such as decision tables or decision trees. This lets business users see how inputs like customer type, order value, or location lead to outputs like approvals, discounts, or routing decisions, without wading through code. Because the logic is expressed as structured, rule-based content, it’s straightforward to review, modify, and test, and keep it separate from how the process flows or how data is presented.

Interfaces focus on how information is shown to users, not on the rules themselves. Process models map the sequence of steps in a process, handling flow and tasks rather than the business decision logic. Expressions encode calculations and conditions in code-like formulas, which can be powerful but are typically less approachable for business readers and aren’t organized as a centralized, readable decision set.
