Reveal correct answer
Correct answer: A
A.
The waterfall model is a sequential approach. In a sequential approach, there is a single delivery and the SE activities are broken down into linear sequential stages where each of these stages depend on the deliverables of previous stages and on the feedback from subsequent stages. See INCOSE SE Handbook 5th Ed., section 2.2.1, p.35.
B.
In an evolutionary approach, both the system and its requirements are delivered into smaller increments; new needs and requirements arise with each incremental deployment. See INCOSE SE Handbook 5th Ed., section 2.2.3, p.38.
C.
In an incremental approach, there are incremental potential deliveries even though requirements are already known from the beginning. See INCOSE SE Handbook 5th Ed., section 2.2.2, pp.36 and 37.
D.
There is a correct option to be chosen among the others.
