The systems analysis and design of information systems has many aspects in common with other organizational processes  It also requires the development of unique skills that are critical to the successful development and maintenance of computer based information systems.

            At the core of systems analysis and design is the understanding of how data and processes for handling data are applied or should be applied by an organization.  It is important to remember that many organizations have found it beneficial to use a systems development methodology.
