Which term is used interchangeably with activity class parameters?

The term that is used interchangeably with activity class parameters is often related to the inputs and outputs that govern how a specific activity within a process works. Activity class parameters define the information that needs to be passed into or returned from an activity when it is executed within a process model.

Node inputs and outputs serve as a concept that clearly aligns with this definition. They refer to the parameters that are set for different activities (or nodes) within a process, establishing what information an activity requires to function (inputs) and what information it will provide after execution (outputs). This makes the terminology applied in activity class parameters directly related to node inputs and outputs.

In contrast, the other terms such as process variables, rule inputs, and process parameters refer to broader concepts within the Appian platform. Process variables are used to hold data relevant to the overall process instance, while rule inputs pertain to the information parameters that are passed to Appian rules specifically. Process parameters generally describe the settings or configurations for a process but do not specifically characterize the nuanced exchange of information for activity-level operations like node inputs and outputs do.
