Main stages of the Software Development Life Cycle (SDLC):
- Planning and Requirements Analysis:
- Defining project goals and functional requirements.
- Gathering and documenting user needs.
- Feasibility analysis and risk assessment.
- Design:
- Developing the overall system architecture and detailed specifications.
- Designing user interfaces, databases, and modules.
- Development:
- Writing code according to design specifications.
- Unit testing of developed modules.
- Testing:
- Performing various types of testing (functional, integration, system, regression) to identify defects.
- Documenting found errors and tracking them.
- Deployment:
- Releasing the finished product to users or into the production environment.
- System configuration and installation.
- Operation and Maintenance:
- Monitoring system performance.
- Fixing errors found after release.
- Making improvements and adding new features.
Different SDLC models (waterfall, Agile, spiral) organize these stages differently, allowing for iteration or strict sequence. QA actively participates in all stages, from requirements analysis (for creating test plans) to post-release support.
