Systems Analysis and Design (SAD) is a broad term for describing methodologies for developing high quality Information System which combines Information Technology, people and Data to support business requirement. The SAD technique is not only limited to IT systems and can be used to create just about anything, from a family house to the international space station. But there is no silver bullet in simplifying the development of computer systems. This principle is still true today. In other words, there is no single, simple technique that developers can use to ensure successful Information Technology (IT) projects. However, there are development methodologies that can be followed which will greatly assist an IT professional in developing and enhancing systems. A methodology is essentially a procedure to get something done. A development methodology can be thought of as a roadmap. While a roadmap for a traveler will provide the details from driving from point A to point B, a development methodology will provide the IT professional with guidelines for taking a system from conception through implementation and beyond. Before going into the details of System Analysis and Design we will shortly discuss the history of it. (System Analysis and Design, Ramakrishnan S)
