Question

Which of the following is an advantage of the Incremental Model?

• A. Complete product is delivered at once
• B. Allows early detection of errors
• C. Does not support customer feedback
• D. Requires no planning

Hint:

The core idea of both Incremental and Iterative models is to get a working piece of software in front of users or testers much earlier than with the Waterfall model. This early delivery and testing is a major advantage.

Answer 1

The Correct Option is B

The Incremental Model is a software development process where requirements are broken down into multiple standalone modules of the software development cycle. Each module goes through the requirements, design, implementation, and testing phases.
Let's analyze the options:
(A) Complete product is delivered at once: This is a characteristic of the Waterfall model, not the Incremental model. The Incremental model delivers the product piece-by-piece.
(B) Allows early detection of errors: Since a working version of the software with some core features (an increment) is produced early in the development cycle, it can be tested early. This allows for the early detection and correction of errors in the core functionality. This is a key advantage.
(C) Does not support customer feedback: This is incorrect. A major advantage of the Incremental model is that customers can see and provide feedback on early increments, which can be incorporated into later ones.
(D) Requires no planning: This is incorrect. The Incremental model requires careful planning to break down the requirements into meaningful increments and to manage the integration of these increments.
