Waterfall Methodology

The Waterfall model is a linear and sequential approach to project management. It consists of distinct phases: requirements, design, implementation, verification, and maintenance. Each phase must be completed before the next begins, making it easy to follow and manage.

Pros:

Clear Structure: The sequential nature makes it easy to plan and manage timelines.
Defined Stages: Each phase has specific deliverables and milestones.
Easier Documentation: Comprehensive documentation at each stage facilitates communication.

Cons:

Inflexibility: Changes in requirements can be challenging to incorporate once a phase is completed.
Delayed Testing: Testing only occurs after implementation, which can lead to late-stage surprises.
Assumes Predictability: Best suited for projects with well-understood requirements.

Agile Methodology

Agile is an iterative approach that emphasizes flexibility, collaboration, and customer feedback. It breaks projects into smaller increments called sprints, allowing teams to adapt quickly to changes and continuously improve the product based on user input.

Pros:

Flexibility: Easily accommodates changes and evolving requirements.
Continuous Feedback: Frequent reviews promote better alignment with customer needs.
Early Delivery: Functional features can be delivered early in the process.

Cons:

Less Predictability: It can be harder to estimate timelines and budgets due to its flexible nature.
Documentation Overload: Agile may lead to less formal documentation, which can be a challenge for larger teams.
Requires Collaboration: Success relies heavily on effective communication among team members and stakeholders.
