What Are the Stages of Software Development Life Cycle (SDLC)?

The Software Development Life Cycle (SDLC) is a structured approach to building high-quality software efficiently. It consists of multiple stages, each ensuring a smooth transition from idea to deployment.

The key stages of SDLC are:

• Planning: Teams define project objectives, analyze feasibility, and create a roadmap. Proper planning minimizes risks and ensures smooth execution.
• Requirement Analysis: Stakeholders gather and document functional and non-functional requirements. Clear requirements help developers build software that meets business needs.
• Design: Architects and developers create system architecture, UI/UX designs, and database structures. This phase ensures scalability, security, and performance.
• Development (Coding): Developers write code based on design specifications. This stage follows coding best practices and version control to ensure maintainability.
• Testing: Software is rigorously tested for bugs, performance issues, and security vulnerabilities. QA teams perform functional, integration, and regression testing to ensure quality.
• Deployment: Once testing is successful, the software is released for users. It may be deployed in phases or all at once, depending on business needs.
• Maintenance & Support: Post-deployment, teams monitor the software, fix issues, and release updates to enhance performance and security.

Each stage of SDLC is crucial for delivering reliable and scalable software. Following a well-structured SDLC improves efficiency, reduces risks, and ensures project success.
