SECTIONA: TRUE/FALSE
Write all your answers in the answer booklet provided.
[10 MARKS]
Question
True
1 Software Engineering is defined as a systematic, disciplined, and
quantifiable approach to the development, operation, and
maintenance of software.
2 A non-functiona I requirement is the task the program must
complete.
3 The first step in the software development lifecycle is Preliminary
Investigation and Analysis.
4 The major drawback of the Spiral Model is that it doesn't work
well for smaller projects.
5 Spiral and Prototyping models doesn't necessitate defining
requirements at the earliest in the lifecycle.
6 Requirement elicitation stage of software development is the
process of converting a system specification into an executable
system.
7 Component design is where you identify the overall structure of
the system, the principal components (sometimes called sub-
systems or modules), their relationships, and how they are
distributed.
8 Change avoidance and Change tolerance are two related
approaches that may be used to reduce the costs of rework.
9 Verification is about checking whether the requirements describe
the intended system objectives and functions.
10 Traceability Matrix is used to track the requirements and to check
the current project requirements are met.
False
