Introduction to systems analysis and design

In the first topic, we’ll discuss what information systems are and
how they are used in organisations, and how they are developed
through a system development life cycle (SDLC). We’ll discuss the
role of the systems analysist and other stakeholders in the SDLC,
and look briefly at some different ways in which the SDLC can be
approached. We’ll conclude with an example illustrating all of the
system development core processes that we will cover in the unit,
and the various models, techniques and diagrams that we will use.
