Brian Wilson was a founding member of the Systems Department at Lancaster University in 1966, where he participated with Professor Peter Checkland in the 'Action Research' of the Department, which led to the emergence of Soft Systems Methodology. The Action Research programme involved working with over 300 organisations in which teams of staff and students effectively acted as consultants to those organisations. Thus for this period and later, when running his own consultancy company, Brian has been involved in the application and development of SSM-related ideas within the real world.
Kees van Haperen is a consultant specialising in the effective implementation within organisations of Soft Systems Methodology. He is currently a visiting lecturer at Loughborough University, UK. He has published a number of papers and book contributions in the fields of crisis management, risk management, organisational learning, requirements management and systems thinking.
