a) Developer
b) User
c) Non-Functional
d) Physical
Answer:d
Explanation: The perspectives or views have been described as the Operational, Functional, and Physical views.All three are necessary and must be coordinated to fully understand the customers’ needs and objectives.
Requirements Analysis is an Iterative Process.
Answer:a
Explanation: Requirements analysis is conducted iteratively with functional analysis to optimize performance requirements for identified functions, and to verify that synthesized solutions can satisfy customer requirements.
Requirements should specify ‘what’ but not ‘how’.
a) True
b) False
Answer:a
Explanation: ‘What’ refers to a system’s purpose, while ‘How’ refers to a system’s structure and behavior.
