programming (SAD) The analysis of the role of a proposed

system and the identification of the requirements that it

should meet. SAD is the starting point for system design.

The term is most commonly used in the context of commercial

programming, where software developers are often classed as

either systems analysts or programmers. The systems

analysts are responsible for identifying requirements

(i.e. systems analysis) and producing a design. The

programmers are then responsible for implementing it.
