The term “Stored expression that can be called from other expressions” defines what object?

The correct answer refers to an "Expression Rule," which is indeed a stored expression that can be called from other expressions within Appian’s environment. Expression Rules are designed to encapsulate logic that can be reused across different components within an application, enhancing efficiency and consistency. By defining common calculations or logic as an Expression Rule, developers can simplify their expression management, reduce duplication, and make maintenance easier, as any changes to the logic only need to be made in one place.

This practice promotes better organization of code and establishes a clear structure, making it easier to collaborate in team environments where multiple users might be working on different parts of an application or process model.

In contrast, a Process Model defines a sequence of tasks or activities in a business process, an Integration refers to connecting Appian with external systems for data exchange, and a Minimum Viable Product is a concept from product development that describes a product with just enough features to satisfy early customers. Each of these options serves different purposes within the Appian platform, but they do not represent the reusable nature of stored logic inherent in Expression Rules.
