Question

What is the major advantage of using Incremental Model?

(a) Customer can respond to each increment

(b) Easier to test and debug

(c) It is used when there is a need to get a product to the market early

(d) Easier to test and debug & It is used when there is a need to get a product to the market early

This question was addressed to me in semester exam.

Question is taken from Evolutionary Software Process Models in division Software Processes, Models and Agile Software Development of Software Engineering

Answer 1

The correct answer is (d) Easier to test and debug & It is used when there is a need to get a product to the market early

To explain: Incremental Model is generally easier to test and debug than other methods of software development because relatively smaller changes are made during each iteration and is popular particularly when we have to quickly deliver a limited functionality system.However, option “a” can be seen in other models as well like RAD model,hence option “d” answers the question.
