Which statement is true about optional processes?

The statement that optional processes are initiated by the user at their discretion is accurate because optional processes are designed to give users flexibility in how they manage their cases. Unlike mandatory processes that must be executed for the case to progress, optional processes allow users to decide whether or not to engage with them based on their specific needs or circumstances in the context of the case.

This approach is beneficial in scenarios where additional steps may provide value but are not essential for the primary case progression. It allows for personalization and adaptation of workflows to better meet individual user needs or varying case complexities. Users can choose to execute these steps when they feel it necessary, thus making the process more user-friendly and tailored.

The other options do not reflect the nature of optional processes. Mandatory requirements, such as needing to execute certain processes every time or categorizing them as mandatory for all business cases, contradict the concept of optionality. Optional processes distinctly provide the choice to the user rather than impose rigid requirements.
