Software Development: Traditional/Waterfall Method
The Waterfall method is a linear and sequential software development approach in which each phase is completed before moving to the next. Here is a high-level overview...
1) Requirements
- Gathering | Collecting and documenting all requirements upfront based on stakeholder inputs
- Analysis | Analyzing and detailing the gathered requirements extensively
2) System Design
- System Architecture | Designing the overall system architecture based on the detailed requirements
- Sub-Component Design | Reduce the system/app into smaller components and designing each in detail
3) Implementation
- Coding | Writing code based on the detailed design specifications developed in prior phases
- Unit Testing | Testing individual components or units of code
4) Integration
- Integrating Components | Combining and integrating individual components to form a complete system
- System/Integration Testing | Testing the integrated system as a whole for functionality and performance
5) Deployment
- Deployment Planning | Preparing the system for deployment and creating a deployment plan
- System Release | Deploying the complete system into the production environment
6) Maintenance
- User Acceptance Testing (UAT): Validating the system with end-users for final acceptance
- Support and Maintenance: Addressing user issues, fixing defects, and providing ongoing maintenance
