(3) Each staff member shall be uniquely identified by an eight-digit employee number.,Functional
(4) The system shall implement patient privacy provisions as set out in HStan-03-2006-priv.,Non-Functional
Explanation
Generating a report and identifying staff by employee number are specific services/behaviors — functional requirements. Availability hours constrain the system's operational behavior (product NFR). Privacy legislation compliance is an external NFR. Note: a security or authentication NFR like privacy compliance may generate additional functional requirements.
