e) Inspection
One task of the requirements engineer is negotiation of requirements. At this point, conflicts between the stakeholders may be discovered. These must then be resolved. In this process, a differentiation is made between various kinds of conflict.
Which two of the listed conflicts are least suitable for handling by the requirements
engineer? (1 Point)
a) Subject matter conflict
b) Value conflict
c) Architectural conflict
d) Cost conflict
e) Structural conflict
c) Architectural conflict
d) Cost conflict
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
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.
In requirements engineering, the use of model-based documentation is very helpful.

c) You ignore the conflict since this is a matter for project management
d) In order to resolve such conflicts you escalate them via the escalation paths defined in the project.
b) You analyze the conflict, try to bring about a solution with a suitable technique and document relevant information about the conflict.
In a meeting held with the goal of validating a set of requirements, two participants become involved in an in-depth discussion about the content of a requirement. One of the participants is of the opinion that the requirement must be realized as described, since the success of the product is otherwise jeopardized.

What is the best way for you to react to this situation? (1 Point)
a) You note both arguments and let the project manager make the decision.
b) You invite all stakeholders to a workshop and try to reach agreement.
c) You prefer the second opinion since you believe that the discussion makes no sense if the requirement cannot be realized.
d) You get together with the affected stakeholders and attempt to reach an agreement on this.
d) You get together with the affected stakeholders and attempt to reach an agreement on this.
