REQUIREMENTS ENGINEERING
DLBCSRE01 – Q&A
Unit 1
Q1 - In requirements engineering, what is the definition of requirements?
a property or capability that a system or subsystem must possess in order to satisfy a contract,
standard, specification, or other formally specified documents
Q2 - Which of the following activities are performed by a requirements engineer?
select and manage stakeholders, check whether all boundary conditions are met, ensure the
traceability of the requirements, and control the detailing of requirements
Q3 - What are the legally binding modal verbs used in requirements engineering to describe
priority?
shall, should, will, and must not
Q4 - In software engineering, not all artifacts have to be in maturity level three at the same time.
What are the latest deadlines in non-Agile projects?
for targets of the system, beginning of system design; for business processes, beginning of system
design; and for interface definition, beginning of system construction
Q5 - Requirements can be divided into three levels based on maturity. What are the definitions of
each level?
At level one, requirements are incomplete, and examples are sufficient; at level two, requirements
are reliable, resilient, and may be incomplete; and at level three, requirements meet all quality
criteria, and are complete and correct.
Unit 2

A stakeholder delivers the requirements of their special field and supports the requirements
engineer by answering their questions or reviewing their documents.

Integrate the Doers, and release those who do not have time to support.
Unit 3
Q1 - If it turns out that the stakeholders have a low level of abstraction, which investigative
techniques should be used?
field observation, apprenticing, interview, and system archaeology
Q2 - Which prototypes exist in relation to the degree of implemented functionality?
horizontal, which are functions in functional layers; and vertical, which are all required elements
from all layers to realize functionality in a narrow width
Q3 - What is the advantage of questionnaires?
Many stakeholders can be interviewed in parallel, digital questionnaires with closed questions can
be easily evaluated, and stakeholders can be locally distributed.
