Sentence-templates can be used to document natural language requirements. You want to introduce such a sentence-template in your project and must convince your project manager of its advantages. Which two arguments do most likely put forward in this discussion? (2 Points)

A. High quality requirements are guaranteed already from the initial documentation.

B. Requirements that are formulated according to the sentence-template contain no linguistic transformation effects.

E. A requirement drafted according to a sentence-template satisfies all quality criteria for requirements.

You are to create a requirements specification for an internet banking software. The system shall perform bank credit transfers and therefore receives from the user, among other information, the bank identification code and the name of the bank. Now things have changed so that only the bank identification code must be entered by the user and the bank name is no longer required. On which part of your documentation do you most likely have to work in order to incorporate this change? (2 Points)

A. Nowhere, since this is a detail for the architecture.

B. In the chapter in which the states of the system are described.

C. As a change in the goals has been communicated, the goals in the specification must be updated.

D. If it is about inputs and outputs of the system, this change has to be worked into the context diagram.

E. You have to adjust the class model and/or the data model, which describe the structure of the system's input and output data.

Requirements documentation can either be natural language or model-based. Which two statements are most applicable? (2 Points)

A. If documentation is model-based, natural language documentation can be dispensed with.

B. As models are more formal, they offer a higher degree of uniqueness compared to natural language.

C. In requirements engineering models are more suitable than textual descriptions to reduce the complexity of the entity being considered.

D. When deciding between model-based and natural language documentation, model-based is preferable.
