What does the software development lifecycle refer to?

The software development lifecycle refers to a structured process for developing software applications. This process encompasses various phases that guide a team from the initial conception of an idea through to the deployment and maintenance of the final product. These phases typically include requirements gathering, design, implementation, testing, deployment, and maintenance.

Each phase has specific goals and deliverables, ensuring that the software is built systematically, addressing user needs and quality requirements. This structured approach helps manage complexity and risk, allows for better planning and resource management, and leads to higher quality software that meets the project specifications.

While the other choices touch on relevant aspects like user feedback, hardware components, or design principles, they do not capture the comprehensive nature of the software development lifecycle which focuses on the end-to-end process of software creation and management.
