Waterfall Model
The Waterfall model is a linear, sequential approach to software development. It is based on the idea that the development process should be planned and executed in a linear fashion, with each phase of the process being completed before moving on to the next.
The Waterfall model includes the following phases:
- Planning: This phase involves defining the goals and objectives of the software, and creating a plan for developing it.
- Analysis: This phase involves gathering and analyzing information about the needs and requirements of the software.
- Design: This phase involves creating the design and architecture of the software.
- Implementation: This phase involves developing the software according to the design.
- Testing: This phase involves testing the software to verify that it meets the specified requirements and functions correctly.
- Deployment: This phase involves installing the software in its intended environment and making it available to users.
- Maintenance: This phase involves providing ongoing support and updates to the software.
The Waterfall model is a well-defined and structured approach to software development, and is well-suited to projects with well-defined requirements and a stable environment. However, it can be inflexible and does not allow for much iteration or change once a phase has been completed.
