The software development cycle, also known as the software development life cycle (SDLC), is a systematic process that outlines the stages involved in creating high-quality software solutions. From conceptualization to deployment, each phase of the cycle plays a critical role in ensuring the creation of reliable, functional, and user-friendly software applications. This guide explores the intricacies of the software development cycle, delving into each step in detail to provide a comprehensive understanding of the process.
