Question
In software engineering, what is the primary purpose of
the software development life cycle (SDLC)?Solution
The Software Development Life Cycle (SDLC) is a process used by software engineers and developers to ensure the efficient, systematic development of high-quality software. SDLC includes distinct phases such as planning, analysis, design, implementation, testing, and maintenance. By following these phases, SDLC provides a framework that helps in building reliable, scalable, and maintainable software while minimizing risks and ensuring that requirements are met. Why Other Options are Wrong: a) While SDLC promotes timely delivery, it does not guarantee that software will always be delivered on time. c) Testing is an integral part of the SDLC to ensure that the software is functional and bug-free. d) SDLC does not automate code generation; it provides guidelines for the development process. e) While stakeholder satisfaction is important, SDLC does not ensure it at every stage.
