SADT has been in use since the mid-seventies, and has inspired many other commercial tools. <ref name ="JM04"/> It 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]] 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].

* [[Structured programming]] in circa 1967 with [[Edgar Dykstra]].

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

* Structured Analysis in circa 1978 with [[Tom DeMarco]], Yourdon, Gane & Sarson, McMenamin & Palmer.

* [[Information Engineering]] in circa 1990 with [[James Martin (author)|James Martin]].
