Structured Analysis and Design Technique

Structured Analysis and Design Technique (SADT) is a systems engineering and software engineering methodology for describing systems as a hierarchy of functions. SADT is a structured analysis modelling language, which uses two types of diagrams: activity models and data models. It is developed since the late 1960s by Douglas T. Ross, and further formalized and published as IDEF0 in 1981.
