Brian Wilson (born 1933 in Newton-le-Willows, Lancashire) is a British systems scientist and honorary professor at Cardiff University, known for his development of soft systems methodology (SSM) and enterprise modelling.
After graduating from University of Nottingham with a B.Sc. and Ph.D. in electrical engineering, nuclear power engineering and control system design, Wilson joined the United Kingdom Atomic Energy Authority where he was concerned with the control and spatial stability of gas-cooled reactors and power plants. In 1966, he left the world of nuclear power engineering and control system design, and became a founder member of the Department of Systems Engineering at the University of Lancaster.
Wilson has had an association with Cardiff University for a number of years, in a variety of roles, and has recently been conferred as an honorary professor in the Department of Computer Science.
He left the University of Lancaster in 1992 to found his own consultancy company, Brian Wilson & Associates, where he continued to develop and apply his particular brand of SSM, leading to the uses of SSM in enterprise model building.
During his time at the University of Lancaster, Wilson was involved in the development of a particular form of business analysis known as soft systems methodology (SSM). This development was driven by the action research programme carried out in that department, in which his particular interest was the application of SSM to information and organisation-based analysis. The work appeared in the book, Systems: Concepts, methodologies and Applications, (editions 1 & 2), published by John Wiley.
