4.2.1. SADT
method
Structured Analysis and Design Technic (SADT) is a method of
American origin, developed in 1977, it spread in the late 1980s as one of the
standard graphic description of a complex system down by functional analysis,
that is to say that the analysis travels from the general to the specific and
detailed. SADT is a systemic approach to modeling a complex system or operating
process.
4.2.1.1. Advantages
· Structure hierarchical level by allowing clarification
and analytical breakdown of the complexity of a system.
· Timeless Diagram.
· Saves time.
4.2.1.2. Limits
· No sequential representation.
· Lack of operation in Boolean logic (AND, OR).
· Inability to a global view, except "the highest
level"
