True or False: Appian process models are designed to be non-executable.

Appian process models are indeed designed to be executable. This means that once a process model is created and configured, it can be deployed and executed to automate business processes. The framework allows for the modeling, execution, and management of workflows, which is a central feature of Appian's capabilities.

Being executable implies that the process models are not just theoretical designs; they consist of defined steps, activities, and flow logic that can interact with user inputs, data, and external systems. This functionality enables organizations to streamline their operations effectively.

In the context of the given choices, identifying that process models are executable underscores the importance of Appian in creating dynamic and responsive business applications that adapt to changing needs and operations, thereby reinforcing the choice as true.
