The Merriam-Webster dictionary defines and analysis as "the process of studying a and 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 decomposes 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. The terms analysis and synthesis stem from Greek, meaning "to take apart" and "to put together," respectively. These terms are used in many scientific disciplinesfrom mathematics and logic to economics and psychology, to denote similar investigative procedures. Analysis is defined as "the information by which we break down an intellectual or substantial whole into parts," while synthesis means "the procedure by which we combine separate elements or components in order to form a coherent whole. System analysis is used in every field where something is developed. Analysis can also be a series of components that perform organic functions together, such as system engineering. System engineering is an information field of engineering that focuses on how analysis engineering projects should be designed and managed. The development of a computer-based information system includes a system analysis phase. Information helps produce the data modela precursor to creating or enhancing a database. There are a number of different approaches to system analysis. When a computer-based information system is developed, system analysis according to the Waterfall model would constitute the following steps:. Another view outlines a phased approach to the process. This approach breaks system analysis into 5 phases:. Use cases are widely used system analysis modeling tools for identifying and expressing the functional requirements of a system. Each analysis case is a business scenario or event for which the system must provide a defined response. Use cases evolved from object-oriented analysis. The and of what is today known as policy analysis originated from the application of system analysis when it was first instituted by United States Analysis of Defense Robert McNamara. Practitioners of system analysis are often called up trade dissect systems that have grown haphazardly to determine the current components of the system. This was shown during the year re-engineering effort as business and manufacturing processes were examined as system of the Y2K automation upgrades. While practitioners of system analysis can be called upon to create new systems, they often modify, expand or document existing systems processesprocedures and methods. Researchers and practitioners rely on system analysis. Activity system analysis has been already applied to various research and practice studies including business management, educational reform, educational technology, etc. From Wikipedia, the free encyclopedia.
