Systems Analysis Definition
     
         (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.
