The System Development Life Cycle (SDLC) is a structured approach used in IT to ensure the consistent development of high-quality systems. It facilitates efficient resource management, risk mitigation, and clear stakeholder communication throughout the development process. By emphasizing thorough documentation, user-centered design, and continuous feedback, the SDLC ensures the system's relevance and effectiveness over time. Discuss the impact AI might have on this process and how it might streamline this process.
