What are traditional design approaches in software development?

Traditional design approaches in software development include methodologies like Waterfall, V-Model, and Spiral. These methods emphasize a structured process.

Can you explain the Waterfall model?

The Waterfall model is a linear approach where each phase must be completed before the next begins. It includes stages like requirements, design, implementation, testing, and maintenance.

What are the pros and cons of using the V-Model?

The V-Model emphasizes verification and validation, ensuring that each development phase has a corresponding testing phase. Pros include clear milestones, but it can be inflexible to changes.

How does the Spiral model differ from the others?

The Spiral model combines iterative development with the systematic aspects of the Waterfall model. It focuses on risk assessment and allows for repeated refinement through cycles.

Which approach is best for large projects?

For large projects, the Spiral model is often preferred due to its flexibility and focus on risk management, but it depends on the project's specific needs.
