Select one. Question 2 options: A Functional Requirement B Nonfunctional Requirementarrow_forwardThe 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.arrow_forward112.

It encompasses all activities undertaken to ascertain the demands of various stakeholders. As a result, requirements analysis refers to the process of analyzing, documenting, validating, and managing software or system requirements. High-quality requirements are documented, actionable, quantifiable, testable, and traceable. They aid in the identification of business opportunities and are established in such a way that system design is facilitated. 6.1 Discuss the importance of systems analysts documenting user requirements.arrow_forward218.
