Solution
Match each software development lifecycle model with its defining characteristic from software engineering.
-
Waterfall model: Characterized by sequential linear phases where one phase must finish before the next begins, leading to inflexible partitioning of the project into distinct stages (matches d).
-
Evolutionary model: Based on producing an initial implementation, exposing this to user feedback, and refining through successive versions, allowing specifications to be developed incrementally (matches a).
-
Component-based software engineering: Relies on integrating pre-existing commercial off-the-shelf software components, which necessitates requirements compromises to adapt to component capabilities (matches b).
-
Spiral development: Risk-driven process model with explicit recognition and management of risks in every loop of the spiral (matches c).
Matching: 1-d, 2-a, 3-b, 4-c, which corresponds to option B.
B
Associating risk analysis with models other than Boehm's Spiral model.
