Exploring the Iterative Model in SDLC

Which of the following is the first phase of the Iterative Model in the Software Development Life Cycle (SDLC)?

• Testing

• Planning

• Design

• Implementation

What is a key advantage of the Iterative Model?

• It requires complete requirements at the start.

• It allows for early detection of risks.

• It is less flexible than the Waterfall Model.

• It is suitable for small projects only.

Which of the following is a disadvantage of the Iterative Model?

• It is inflexible to changes.

• It can be more costly than other models.

• It does not allow for feedback.

• It requires less user involvement.

How does the Iterative Model differ from the Waterfall Model?

• The Iterative Model is linear, while the Waterfall Model is cyclical.

• The Iterative Model allows for changes after each iteration, while the Waterfall Model does not.

• The Waterfall Model is more flexible than the Iterative Model.

• The Iterative Model requires complete requirements upfront.

In which real-world application is the Iterative Model commonly used?

• Small-scale projects with fixed requirements

• Large-scale projects with evolving requirements

• Projects with no user feedback

• Projects with a short timeline

What is the primary focus during the feedback and iteration process in the Iterative Model?

• Minimising costs

• Enhancing user interface

• Improving product quality and functionality

• Reducing development time

Which phase follows the Design phase in the Iterative Model?

• Testing

• Implementation

• Planning

• Evaluation

What is a significant benefit of using the Iterative Model in software development?

• It eliminates the need for testing.

• It allows for early user feedback.

• It reduces the need for documentation.

• It requires less time for development.

Which of the following is a challenge when using the Iterative Model?

• Lack of user involvement

• Difficulty in managing changes

• High initial costs

• Complexity in project management

How does the Iterative Model handle changes in requirements?

• Changes are not allowed once development starts.

• Changes are incorporated in subsequent iterations.

• Changes are only allowed during the testing phase.

• Changes are ignored to maintain the timeline.
