SDL (Software Development Lifecycle)

The Software Development Lifecycle (SDL) is a structured process used to plan, create, test, and maintain software applications. It ensures that software is developed efficiently, meets user needs, and remains secure. The main stages typically include planning, designing, coding, testing, deployment, and ongoing support. By following these steps, teams can organize their work, identify problems early, and deliver high-quality software that functions as intended. SDL helps manage complexity and reduces risks, making the development process more predictable and effective.
