A. Questionnaires / interviews
B. Apprenticing
C. Field surveys
D. Role playing
E. Brainstorming
You are employed as a requirements engineer in a company that develops control software for electric motors. During your work it becomes increasingly evident that the developers are very well aware of the necessary requirements, even though the requirements are not documented in their entirety. Nevertheless, you decide to document requirements systematically. Which two of the following arguments justifies this step? (2 Points)
Documenting requirements systematically is important, because...
A. ... implementation without documented requirements is not possible.
B. ... non-documented requirements are difficult to negotiate between the stakeholders.

D. ... documented requirements are also good requirements.
In delimiting system and system context, a differentiation is made between the system boundary and the context boundary. This differentiation is important in order to understand which aspects impact on the requirements of the system to be developed and which do not. Choose the two correct statements. (2 Points)
A. The context boundary separates the system from the system context.
B. The system boundary and the context boundary define the system context.
C. The system context includes all aspects that are not relevant to the requirements of the planned system.
D. Only the aspects within the system boundary must be taken into account in order to determine the requirements of the system to be developed.
E. The selection of the system boundary establishes which aspects are covered by the system to be developed and which lie beyond its scope.
Which two statements are correct with regard to the introduction of a requirements engineering tool? (2 Points)

B. Risks associated with the introduction can be identified through a pilot operation
C. The requirements engineering processes must be clearly defined before introduction
D. The license costs are generally the greatest cost block relating to the introduction of a requirements engineering tool
