What design object is used to capture business rules in Appian?

The decision object is specifically designed to capture and manage business rules in Appian. It allows for the definition of complex conditions and the logic needed to evaluate those conditions based on input data, leading to specific outcomes. This capability is essential for automating decision-making processes and ensuring that business rules are applied consistently across the application.

The decision object can be utilized in various contexts within Appian, such as in process models and user interfaces, where dynamic decision-making is necessary. It supports logical expressions and can simplify the structure of other design objects by centralizing rule definitions, making it easier to update and maintain business logic over time.

In contrast, process models focus on orchestrating the flow of work and activities rather than specific business rules, while record types are primarily used for viewing and managing data. Interfaces are designed for user interactions and presenting information, rather than capturing business logic. Thus, the decision object stands out as the appropriate choice for capturing business rules within the Appian platform.
