Systems Analysis is a method used to study and evaluate complex systems, often in the context of information technology. It involves understanding how different components of a system interact and function together to achieve specific goals. Analysts gather requirements, identify problems, and propose solutions to improve system efficiency and effectiveness. The process typically includes defining system requirements, modeling system behavior, and assessing potential impacts of changes. By using various tools and techniques, such as data flow diagrams and use case analysis, systems analysts help organizations make informed decisions about system design and implementation.
