Waterfall vs. Agile are two distinct approaches to software development, each with its own methodologies, processes, and suitability for different types of projects. Here’s a comparison between the two:

Waterfall Methodology

Overview:

Linear and Sequential: The Waterfall model is a traditional approach that follows a strict, linear progression through predefined phases: Requirements, Design, Implementation, Verification (Testing), and Maintenance.

Agile Methodology

Overview:

Iterative and Incremental: Agile is a flexible approach that promotes iterative development, allowing for frequent reassessment and adaptation throughout the project.

Characteristics:

1. Iterations: Projects are divided into small, manageable increments (sprints) that typically last 2-4 weeks.

2. Collaboration: Emphasizes collaboration between cross-functional teams and stakeholders, with regular feedback and adjustments.

3. Adaptability: Requirements can evolve based on feedback, allowing teams to respond to changes quickly.

4. Continuous Delivery: The product is delivered in increments, allowing for continuous testing and improvements.

Conclusion

The choice between Waterfall and Agile depends on the project’s complexity, requirements stability, and customer involvement. Waterfall may be more suitable for projects with well-defined requirements and minimal expected changes, while Agile is better for projects that require flexibility and close collaboration with stakeholders.
