Systems Analysis Definition
SAD
<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.
