The Waterfall model stands as an early and time-honored software development approach. Marked by its linear and sequential process, each developmental phase is concluded before transitioning to the subsequent one. This methodology draws inspiration from manufacturing and construction procedures, mirroring the need to finish one step before commencing the next.
Examples of Waterfall Model
Waterfall model was employed for crafting enterprise applications:
Customer Relationship Management (CRM) systems
Human Resource Management Systems (HRMS)
Supply Chain Management Systems
Inventory Management Systems
Point of Sale (POS) systems
The Waterfall model encompasses a series of welldefined stages:
Advantages of the Waterfall Model:
The model's sequential structure offers a well-defined journey from beginning to end. Every phase is marked by distinct deliverables and milestones, simplifying the monitoring of project advancement.
Thorough documentation is highlighted within each phase, facilitating the preservation of project decisions, requirements, design selections, and additional information.
The Waterfall model thrives when initial requirements are solid and clear, as it operates most efficiently when changes are minimized after the requirements phase.
Disadvantages of the Waterfall Model:
The rigid structure of the Waterfall model poses challenges in adapting to evolving requirements. If changes arise after progressing to design or implementation, making adjustments becomes complex and expensive.
Incorporating stakeholder and user feedback often occurs after the software's full development, posing challenges in integrating their input during the initial stages of the process.

Summary
While the Waterfall model provides a methodical and organized approach to software development, it fits best with projects having clear and established requirements. Yet, its rigidity and limited user engagement can pose difficulties in adjusting to evolving demands and integrating feedback. This has led to the rise in popularity of Agile methodologies, which excel in addressing these limitations and offering dynamic and collaborative solutions in software development
