Requirements elicitation: Your company has received a customer contract to develop a system for the scheduling of the customer's delivery vans.

You have arranged appointments for interviews with three key members of the customer's staff, and are now preparing interview questions. Which of the questions below are appropriate interview questions for the requirements elicitation? (2 Points)
A. What are the most important technical terms for the application and how are they defined?
B. If the delivery deadline is not met, is a contract penalty to be paid?
C. What data quantities / data rates are to be processed?
D. When is the installation of the completed system to be started?

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.
C. Drafting requirements in accordance with sentence-templates can be learned in a short time.
D. The use of a sentence-template basically delivers greater information content.
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 statesof 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 changehas 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.
As input for the system development, the Board of Directors of an automotive manufacturer has specified the following goals:
1.
The infotainment system should be easy to operate.
2.
The user must be able to operate the system without becoming distracted from the road traffic.
3.
The system should function without an additional power source.
4.
The system should be configurable for various models of car.
With which two approaches can these goals be detailed and refined best? (2 Points)
A. Clear specification of the goals with the help of use casesand the associated activity diagrams.
B. Documentation of the goals in a sequence diagram.
C. Decomposition of the goals with the help of goaltrees, in order to obtain more concrete goals.
