Software Process Models unit 1

Which of the following is NOT a phase in the Waterfall Model?

• Requirement Analysis

• Design

• Maintenance

• Rapid Prototyping

What is the main drawback of the Waterfall Model?

• It is easy to implement

• It is difficult to manage

• Changes are difficult to accommodate after the development starts

• It does not require a lot of documentation

The Iterative Model is best suited for projects where:

• Requirements are well-defined and stable

• No changes are expected after development starts

• Requirements are unclear or expected to change

• The project has a very short timeline

The Incremental Model involves:

• Delivering the entire system at once

• Developing the system in small parts (increments) and integrating them

• Avoiding iteration

• Developing a prototype and discarding it after use

Which of the following software process models allows overlapping phases?

• Waterfall Model

• Iterative Model

• Incremental Model

• Both B and C

Which of the following is a key characteristic of the Rapid Application Development (RAD) model?

• Emphasis on detailed documentation

• Strict sequential phases with minimal user involvement

• Use of reusable components and iterative prototyping

• Long development cycles

Which of the following best describes the Waterfall Model?

• Linear and sequential

• Iterative and incremental

• Agile and flexible

• Rapid and prototype-driven

The Incremental Model differs from the Waterfall Model because:

• It follows a strict linear sequence

• It delivers the software in small increments rather than a single final product

• It avoids testing until the end

• It is only used for small projects

In the Spiral Model, each iteration is called a:

• Phase

• Increment

• Spiral cycle

• Prototype

Which software process model is best suited for time-sensitive projects requiring quick development?

• Waterfall Model

• Spiral Model

• Rapid Application Development (RAD)

• Incremental Model
