Q2.8. You are leading a JAD session with a cross-section of stakeholders to determine nonfunctional requirements, and so far you have just generated a lot of confusion. Some stakeholders think that nonfunctional means broken, others think it means low priority items. Which of these description best describes a nonfunctional requirement?

(a) Nonfunctional requirements describe the characteristics of a system and the environment it needs to operate in.

(b) Nonfunctional requirements describe the requirements that are important for the developers to know the technical constraints of the system.

They are typically not of primary concern to the business.

(c) Nonfunctional requirements describe the qualities of the system. They can help make the system easier to use, but they are secondary to functional requirements.

(d) Nonfunctional requirements describe the system, whereas functional requirements describe the business.
