Structured Systems Analysis and Design Method (SSADM)
Structured Systems Analysis and Design Method (SSADM) is a systems approach to the analysis and design of information systems. SSADM was produced for the CCTA, a UK government office concerned with the use of technology in government, from 1980 onwards. The names “Structured Systems Analysis and Design Method” and “SSADM” are now Registered Trade Marks of the Office of Government Commerce (OGC), which is an Office of the United Kingdom’s Treasury.
Introduction System design methods are a discipline within the software development industry which seek to provide a framework for activity and the capture, storage, transformation and dissemination of information so as to enable the economic development of computer systems that are fit for purpose.
SSADM is one particular implementation and builds on the work of different schools of development methods, some of the key members of which included:
- Peter Checkland, developer of the Soft Systems Methodology, an instance of Systems thinking
- Larry Constantine, developer of Structured Design and inventor of data flow diagrams
- Wayne Stevens, coauthor, with Larry Constantine and Glenford Myers, of one of the seminal papers on Structured Design
- Chris Gane & Trish Sarson, authors of Structured Systems Analysis: Tools and Techniques
- Ed Yourdon, developer of the Yourdon method in Structured Programming
- Michael A. Jackson, developer of Jackson Structured Programming
