It received extensive use starting in 1973 by the US Air Force [[Integrated Computer Aided Manufacturing]] program.

According to Levitt (2000) "itSADT is "part of a series of structured methods, that represent a collection of analysis, design, and programming techniques that were developed in response to the problems facing the software world from the 1960s to the 1980s. In this timeframe most commercial programming was done in [[COBOL]] and [[Fortran]], then [[C (programming language)|C]] and [[BASIC]]. There was little guidance on “good” design and programming techniques, and there were no standard techniques for documenting requirements and designs. Systems where getting larger and more complex, and the information system development became harder and harder to do so. As a way to help manage large and complex software. Since the end 1960 multiple Structured Methods emerged".<ref name="DL00" >Dave Levitt (2000):[http://faculty.inverhills.edu/dlevitt/CS%202000%20(FP)/Introduction%20to%20Structured%20Analysis%20and%20Design.pdf Introduction to Structured Analysis and Design].

SADT was among a series of similar structured methods, which had emerged since the 1960 such as:

* [[Structured programming]] in circa 1967 with [[Edsger W. Dijkstra]].

* [[Structured Design]] around 1975 with [[Larry Constantine]] and [[Ed Yourdon]]
