Why is the Spiral Model recommended for large, complex projects?

Spiral Model combines elements of both waterfall model and iterative development, making it suitable for high-risk projects. Signup and view all the answers

What are the key characteristics of the Spiral model of the Software Development Life Cycle (SDLC)?

The key characteristics of the Spiral model are: 1) Allows for incremental releases of the product through iterations, 2) Uses a risk-driven and controlled prototyping approach, 3) Assesses prototyping results and determines risk areas to prototype further, 4) Explores the system at greater depth with each iteration, adding more detail.

How does the Spiral model differ from the Waterfall model in terms of software development approach?

The Spiral model takes a gradual and iterative approach, in contrast to the strict sequential flow of the Waterfall model. It allows for incremental releases and incorporates risk analysis and prototyping at each iteration. Signup and view all the answers

When is the Spiral model particularly suitable for software development projects?

The Spiral model is appropriate for exploratory projects that are working in an unfamiliar domain or with unproven technical approaches. Signup and view all the answers

What is the purpose of risk-driven prototyping in the Spiral model?

The purpose of risk-driven prototyping in the Spiral model is to identify and mitigate high-risk areas early in the development process through iterative prototyping. Signup and view all the answers

How does the Incremental approach differ from the Spiral approach in software development?

The Incremental approach focuses on building and delivering the software in increments, while the Spiral approach incorporates risk analysis and prototyping at each iteration to gradually explore and refine the system. Signup and view all the answers

Explain the key difference between the Agile/Scrum approach and the Waterfall approach in software development.

The Agile/Scrum approach is dynamic and iterative, with cross-functional teams working in short 'Sprints' to build and release software incrementally based on customer feedback. In contrast, the Waterfall approach follows a strict, sequential flow with all requirements defined upfront. Signup and view all the answers
