12.1 Program Development Life Cycle Cambridge iAS 9618

What is the primary purpose of a development life cycle in programming?

• To provide a structured approach to developing software.

• To write the code of the program.

• To reduce the size of the program.

• To distribute the program to users.

Which of the following is an example of a type of development life cycle?

• Waterfall, Iterative, Rapid Application Development (RAD).

• Random, Predictive, Structural.

• Compilation, Debugging, Testing.

• Design, Coding, Testing.

What is a characteristic of the Waterfall development life cycle?

• It follows a linear, sequential approach where each stage is completed before moving to the next.

• It allows for iterative improvements during the development process.

• It is best suited for projects that require quick delivery of software.

• It allows multiple stages to occur simultaneously.

What is a benefit of the Waterfall model?

• It provides a clear structure and defined stages.

• It is flexible and adaptable during development.

• It minimizes documentation requirements.

• It is ideal for projects with frequent changes.

What is a major drawback of the Waterfall model?

• It is inflexible and difficult to adapt to changes once development has started.

• It requires less documentation than other models.

• It allows for early testing of software components.

• It is suited for projects that have vague or unclear requirements.

What does the Iterative development life cycle allow?

• It allows development to be repeated in cycles, where each iteration improves upon the last.

• It completes all stages in a strict order with no room for revision.

• It requires only one round of testing before the software is finalized.

• It focuses on gathering detailed user requirements from the beginning.

What is a benefit of using the Iterative model?

• It allows for flexibility and adaptation to changes during development.

• It does not require testing after the first iteration.

• It speeds up the delivery of the software with minimal changes.

• It eliminates the need for documentation.

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

• It may lead to scope creep due to continuous changes.

• It is easier to manage as each stage is clearly defined.

• It results in fewer cycles, making it less time-consuming.

• It does not require user feedback.

In Rapid Application Development (RAD), what is the primary focus?

• To quickly develop and deliver software with the help of prototyping and user feedback.

• To follow a strict, step-by-step approach without flexibility.

• To minimize interaction with the client.

• To reduce the number of testing phases.

What is a major benefit of Rapid Application Development (RAD)?

• Faster development and more frequent releases of software.

• Higher costs due to extended project timelines.

• It involves a lot of documentation and slower development.

• It is less dependent on user feedback.
