ISQI Certified Professional for Requirements Engineering - Foundation Level Examination Sample Questions:

1. 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) ... non-documented requirements are difficult to negotiate between the stakeholders.
B) ... implementation without documented requirements is not possible.
C) ... the coverage of the requirements by means of test cases cannot be checked.
D) ... documented requirements are also good requirements.

2. 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) Only the aspects within the system boundary must be taken into account in order to determine the requirements of the system to be developed.

On which part of your documentation do you most likely have to work in order to incorporate this change? (2 Points)

A) In the chapter in which the statesof the system are described.
B) If it is about inputs and outputs of the system, this changehas to be worked into the context diagram.
C) Nowhere, since this is a detail for the architecture.
D) As a change in the goals has been communicated, the goals in the specification must be updated.
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.
