The Software Development Lifecycle (SDLC) is a structured process for developing software, ensuring quality and efficiency from planning to maintenance.
🔧 Key Phases of SDLC
Requirements Analysis
- Define user needs and system constraints.
- 📌 Use tools like User Stories to capture functional requirements.
System Design
- Create architectural blueprints and technical specifications.
- 🧱 Focus on scalability and security during this phase.
Implementation
- Develop code using agile or waterfall methodologies.
- 🧪 Integrate automated testing frameworks for reliability.
Testing
- Validate functionality, performance, and security.
- 📊 Use test_case_management to track issues.
Deployment
- Release the software to production environments.
- 🚀 Prioritize rollback plans for critical systems.
Maintenance
- Monitor and update the software post-launch.
- 📌 Explore continuous_integration for streamlined updates.
