The key concept that Use Cases document is ________________________________________________.

	A.	Use cases describe the different technology components that are used in the system.
	B.	Use Cases describe the procedures that users will employ as they work on the system.
	C.	Use Cases list the system requirements that are included in a particular program.
	D.	Uses Cases describe how actors, including users and other computer systems, interact with the system and how the system responds to their input.

Sources of information system requirements include the following, EXCEPT:

	A.	interviews with users and domain experts
	B.	Existing system processes, programs and reports
	C.	results from testing of the system
	D.	system prototypes

The following statements are true about user requirements for information systems, EXCEPT:

	A.	A large percentage of defects in information systems can be traced back to issues with collecting accurate requirements.
	B.	Requirements represent characteristics of information systems including necessary features and functions, capabilities required and the how they will generate value for users
	C.	It is usually better to collect user requirements later in a project once they have a better understanding of what the system should do
	D.	Requirements can generally be categorized as functional and non-functional requirements.

Use Case Diagrams ________________________________________________________.

	A.	show subsets of activities that are included in Use Cases.
	B.	show the relationships between actors and related Use Cases.
	C.	show an inventory of all the Use Cases developed for a system.
	D.	show how the requirements in the Requirements Traceability Matrices are related to each other
