In the Waterfall Methodology, the Design phase follows Requirements Gathering, where the system's architecture and detailed specifications are defined.

The Waterfall Methodology is characterized by its linear and sequential nature, not its iterative and incremental approach.

The main objective of the Testing phase is to identify and rectify defects in the software product.

Deployment is the phase where the developed software product is installed and made available to end-users.

The Waterfall Methodology is criticized for its rigidity, high risk of project failure due to its sequential nature, and difficulty in accommodating changes once a phase is completed.

The Waterfall Methodology offers a clear and structured approach, making it easy to manage and track project progress. It is also suitable for projects with stable requirements.

Implementation is the phase where the actual coding and development of the software product takes place.

Maintenance is not a phase in the traditional Waterfall Development Methodology.

The Requirements Gathering phase aims to gather and analyze stakeholder needs and define the scope and objectives of the software product.

Developing test cases is not typically done during the Design phase; it is part of the Testing phase.

During the Implementation phase, a detailed implementation plan is created, outlining the steps and resources required to develop the software product.

Creating a project plan is not a typical activity performed during the Testing phase; it is usually done during the initial planning stages of the project.

Deployment is the phase where the developed software product is installed and made available to end-users in the production environment.

The Waterfall Methodology is often criticized for its lack of flexibility to accommodate changes once a phase is completed.

The main objective of the Deployment phase is to install and make the developed software product available to end-users.
