during development
b. No requirements change take place later in the life cycle
c. No technical risks occur later in the life cycle
d. No inaccuracy in the project estimations occur
e. Project team consists of competent programmers
Answer :- a. No rework to any artifact developed during a life cycle phase is ever needed later during development
10. Which one of the following sentences explains the possible reason for the following observation:
“As the development of a software gets underway using waterfall model of development, the later
the phase in which a defect gets detected, the more expensive is its removal.”
