Explanation A complete requirement is one that provides all the information necessary for the reader to understand it without ambiguity or confusion. This requirement is incomplete because it does not specify what constitutes an incident-related event, who are the appropriate stakeholders, what is the expected timeliness and reliability of the notification, and how the notification should be delivered. These details are essential for designing and testing the solution that meets the requirement.
