This article is about the interdisciplinary field. For the analysis of systems in electrical engineering, see system analysis. The Merriam-Webster dictionary defines system analysis as “the process of studying a procedure or business in order to identify its goals and purposes and create systems and procedures that will achieve them in an efficient way”.
Another view sees system analysis as a problem-solving technique that breaks down a system into its component pieces for the purpose of the studying how well those component parts work and interact to accomplish their purpose. The field of system analysis relates closely to requirements analysis or to operations research. It is also “an explicit formal inquiry carried out to help a decision maker identify a better course of action and make a better decision than she might otherwise have made.
