Which of the following best describes the role of a software development lifecycle (SDLC)?

The role of a software development lifecycle (SDLC) is fundamentally centered on the processes and practices involved in developing and maintaining software programs. It encompasses all stages of software development, including requirements gathering, design, implementation, testing, deployment, and maintenance. This structured approach helps ensure that software quality is managed effectively while meeting user needs and business objectives.

Focusing on developing and maintaining software programs includes not just the initial creation of software but also continuous updates and improvements, making it a comprehensive framework for managing the software life from conception to retirement. The SDLC is crucial for delivering high-quality software in a systematic, efficient, and repeatable manner.

In contrast, user account management, website creation, and computer hardware design are distinct activities that do not encapsulate the breadth of processes involved in the SDLC. Each of these focuses on specific aspects of technology rather than the systematic development and upkeep of software itself.
