What is the main purpose of the software development lifecycle (SDLC)?

The main purpose of the software development lifecycle (SDLC) is to plan, create, test, and deploy software systematically. This structured approach allows teams to move through various stages of development, ensuring that each phase—requirements gathering, design, implementation, testing, and maintenance—receives appropriate attention and resources. By following the SDLC, organizations can reduce risks, improve quality, and make sure that the final product meets the specified requirements and functions as intended. This cycle is crucial for managing the complexities of software production and helps in maintaining a clear timeline and goals throughout the development process.

In contrast, troubleshooting software issues typically occurs within the maintenance phase of the lifecycle rather than being a primary purpose of the SDLC. Managing server architecture is more related to infrastructure than the direct processes of software development. Ensuring data integrity is also important but is usually one of several considerations during the development and testing phases, rather than the overarching goal of the SDLC.
