Waterfall Model in Software Engineering

What is the Waterfall Model?

The Waterfall Model is a sequential approach to software development where each phase must be completed before the next one begins. It is a linear process where progress flows in one direction, resembling a waterfall.

Purpose of the Waterfall Model

The purpose of the Waterfall Model is to provide a structured and systematic approach to software development. It helps in clearly defining the steps and stages of development, making it easier to manage and track progress.

How Does it Work?

The Waterfall Model works by dividing the software development process into distinct phases: requirements, design, implementation, testing, deployment, and maintenance. Each phase has specific goals and deliverables, and work on the next phase begins only after the previous one is completed.

Benefits

  1. Clear Structure: Offers a clear and organized approach to development with defined stages and deliverables.
  2. Easy to Manage: Simplifies project management as each phase is completed in a step-by-step manner.
  3. Well-Documented: Provides comprehensive documentation at each stage, which can be useful for future reference and maintenance.

Conclusion

The Waterfall Model is a traditional and straightforward approach to software development. It helps in organizing and managing the development process by breaking it into sequential phases. While it offers a clear structure and ease of management, its linear nature may not accommodate changes easily during the development process.
