Essence of Systems Analysis and Design

SSADM is a waterfall method for the analysis and design of information systems. SSADM can be thought to represent a pinnacle of the rigorous document-led approach to system design, and contrasts with more contemporary agile methods such as DSDM or Scrum. SSADM is one particular implementation and builds on the work of different schools of structured analysis and development methods, such as Peter Checkland's soft systems methodology , Larry Constantine's structured design , Edward Yourdon's Yourdon Structured Method , Michael A. The SSADM method involves the application of a sequence of analysis, documentation and design tasks concerned with the following. In order to determine whether or not a given project is feasible, there must be some form of investigation into the goals and implications of the project. For very small scale projects this may not be necessary at all as the scope of the project is easily understood.

This is why it is mainly designed for large-scale Information Systems with high volume business events. SSADM specifies exactly the flows and tasks of a development project and produces a detailed documentation of the project. SSADM sticks to the traditional waterfall model, which allows review of each stage but requires its accomplishment before the next one can begin. Its main benefits are: Improvement of quality, detailed documentation of the development stages, and reusability for similar projects that follow. But these points are not likely to be taken into consideration in practice. This is due to the danger of over-analysing, which can be very time and -cost consuming. Especially for small or medium-sized companies, huge delays can lead to serious financial and resource problems.
