In an activity step, which part indicates the action to perform?

In an activity step within Pega, the method is the component that specifies the action to perform. This refers to the particular function or operation that will be executed during the activity, such as updating a property, creating a new instance, or calling a different activity. The method is essentially the instruction that defines what the application should do at that step in the process.

The step description primarily serves as a human-readable summary of the activity step, providing context to developers or business analysts but not indicating the specific action. Parameters are used to pass data or values that assist in executing the method but do not inherently describe the action themselves. Conditions can control the execution of methods by determining if a particular step should run based on certain criteria, but they do not specify what action to take. Thus, the method is the key element that designates the specific action to be performed in an activity step.
