Which one of the following is the third step in System Analysis?

System analysis is the process of understanding and specifying the requirements of a system. The third step in system analysis is analysis and design, which involves creating models and diagrams to represent the system’s structure, behavior, and interactions. Analysis and design also includes identifying and evaluating alternative solutions, and selecting the best one based on criteria such as cost, feasibility, and user satisfaction. References: Certified Information Technology Manager (CITM) - gaqm.org, Module 3 – System Analysis and Design; CITM 305 - Systems Analysis and Design - Toronto Metropolitan University, Course Description and Sample Course Outline.
