ITIL 4 Foundation Practice Exam

Non-functional requirements typically capture what aspect from stakeholders?

1. The monetary expectations of stakeholders

2. The desired features of the product

3. The performance and quality attributes of the service

4. The sponsorship responsibilities of each department

The correct answer is: The performance and quality attributes of the service

Non-functional requirements play a crucial role in determining how a system or service performs rather than what the system does. They focus on the quality attributes that stakeholders expect, which include aspects like performance, security, reliability, scalability, and usability. These characteristics provide a framework for evaluating the system's overall quality and user satisfaction, ensuring that it meets stakeholders' expectations without detailing specific functionalities. For example, stakeholders might specify that a service should be able to handle a certain number of transactions per second (performance), have an uptime of 99.9% (reliability), or comply with specific regulatory standards (security). While functional requirements detail the specific actions and features of the service, non-functional requirements ensure that the service operates at the desired level of performance and meets various quality standards expected by stakeholders. This distinction makes non-functional requirements fundamental in aligning the service's operational capabilities with stakeholder expectations.
