The Software Development Life Cycle (SDLC) is a framework comprising phases such as requirements gathering, design, development, testing, deployment, and maintenance, all crucial for delivering high-quality software efficiently. Organizations spend significant resources on deployment efforts, with models like Agile and DevOps reducing delivery times and enhancing team collaboration. The SDLC stages involve detailed planning, design decisions, building, testing, and operationalization to ensure software quality and performance. Various models have emerged over time, including the waterfall, iterative, and Agile models, each addressing different challenges and offering unique approaches to software delivery. Understanding the SDLC not only aids in improving delivery speed and quality but also enhances DevOps performance, incorporating feedback and insights to continuously deliver value. As the software industry evolves, the SDLC adapts to changing tools, processes, and demands, empowering teams to manage development complexity effectively.
