Who may not actively process a case but requires notifications about changes?

The correct choice identifies an individual who does not directly engage in the processing of a case yet has a vested interest in its progress or outcome. A customer, in this context, often seeks to be informed about updates or changes regarding their case, even though they might not be actively managing the tasks involved.

Notifications serve to keep customers apprised of significant developments, ensuring they are aware of changes that affect them without needing to intervene in the case's progression. This role emphasizes the importance of communication and transparency in service delivery, especially in situations where stakeholders are impacted by decisions or events.

While owners are responsible for overseeing the case and actively managing its progression, and interested parties may be involved to some degree but share responsibilities with other stakeholders, the administrator typically has a more operational role focused on case management rather than maintaining an advisory or informed position without direct participation. Hence, customers are distinctly defined as requiring updates without the obligation of participation in the case's active processing.
