What does the term software development lifecycle refer to?

The term software development lifecycle refers to a process for developing software systematically. This lifecycle encompasses various stages through which software is developed, from initial requirements gathering and planning to design, implementation, testing, deployment, and maintenance. Each stage is designed to ensure that the software meets the needs of its users and stakeholders while also adhering to quality standards.

By following a systematic approach, teams can effectively manage complexity, facilitate communication, and monitor progress throughout the development process. This careful management helps reduce risks and improves the overall quality of the final product. The systematic nature of the software development lifecycle promotes efficiency and organization, which are vital in delivering reliable and functional software.

While frameworks for project management, user interface design, and debugging techniques are important aspects of software engineering, they do not encompass the broader process of developing software systematically. The lifecycle itself serves as the foundational framework that guides how software is conceived, built, and maintained.
