The Seven Phases of the Software Development Life Cycle
The Software Development Life Cycle (SDLC) is a structured process used to design, develop, and maintain high-quality software. It typically consists of seven key phases: planning, analysis, design, development, testing, deployment, and maintenance.
With the help of modern tools like Jira, Git, Visual Studio Code, Jenkins, and Selenium, teams can efficiently manage, build, test, and deploy software solutions.
Key Phases and Tools
