The systems movement, now 40 years old, is made up of many associations of systems thinkers from different disciplines all over the world. The United Kingdom Systems Society (UKSS) was formed in 1978. Today it has over 300 members and is committed to the development and promotion of "systems" philosophy, theory, concepts and methodolo gies for improving decision making for the benefit of organizations and wider society. The first UKSS International Conference was held at the University of Hull in July ofHuddersfield 1989. Since then we have held International Conferences at the Universities (1991) and Paisley (1993). The UKSS International Conferences are now an established biannual event and this, our fourth international conference, will be jointly hosted by the Universities of Hull and Humberside. Systems science is considered to be a trans-discipline which promotes critical and effective intervention in complex organisational and social problem situations. As such it traverses "hard," through "soft" to "critical" systems thinking and methodologies. Yet, despite the currently robust state of the UKSS the systems movement cannot be described as an international movement: different subdisciplines are at different stages of development and are often engaged in pursuing their own particular interests and themes with little "conversation" between the subdisciplines despite their common interest in systems."

The 21st century is now almost upon us and, whilst this represents a somewhat artificial boundary, it provides an opportunity for reflection upon the changes, and the accelerating pace of change, in our social, economic, and natural environments. These changes and their effects are profound, not least in terms of access to information and communication technologies, at once global in effect and manifest locally. These changes and their consequent demands are reflected in the theme of this volume: Synergy Matters, proceedings from the 6th UK Systems Society International Conference.

Welcome to the proceedings of the Seventh International Conference of the UK Systems Society being held at York University, United Kingdom from July 7th to 10th, 2002. It is a pleasure to be able to share with you this collection ofpapers that have been contributed by systems thinkers from around the world. As with previous UKSS conferences, the aim ofthis conference is to encourage debate and promote development of pertinent issues in systems theory and practice. In current times where the focus has moved from 'information' to 'knowledge' and where 'knowledge management', of everyday speak, it seemed fitting to 'knowledge assets' and so on, have become part offer a conference title of'Systems Theory and Practice in the Knowledge Age'. In keeping with another tradition of previous conferences, the UKSS Conference 2002 Committee decided to compile a collection ofdelegates' papers before the event as a platform from which to launch discussions in York. Ideas presented in the following papers will, undoubtedly, be developed during the dialogue generated at the conference and new papers will emerge. In his abstract for his plenary at this conference, Professor Peter Checkland throws down the gauntlet to systems thinking and its relevance in the knowledge age with the following statement: "30 Years In The Systems Movement: Disappointments I Have Known and Hopes/or the Future Springing from a lunchtime conversation at an American University, the Systems Movement is now nearly 50 years old.

Peter A. Coming Palo Alto, CA November, 2000 This volwne represents a distillation of the plenary sessions at a unique millenniwn year event -a World Congress of the Systems Sciences in conjunction with the 44th annual meeting of the International Society for the Systems Sciences (ISSS). The overall theme of the conference was "Understanding Complexity in the New Millenniwn. " Held at Ryerson Polytechnic University in Toronto, Canada, from July 16-22,2000, the conference included some 350 participants from over 30 countries, many of whom were representatives of the 21 organizations and groups that co-hosted this landmark event. Each of these co-host organizations/groups also presented a segment of the program, including a plenary speech. In addition, the conference featured a nwnber of distinguished "keynote" speeches related to the three daily World Congress themes: (1) The Evolution of Complex Systems, (2) The Dynamics of Complex Systems, and (3) Human Systems in the 21st Century. There were also seven special plenary-level symposia on a range of timely topics, including: "The Art and Science of Forecasting in the Age of Global Wanning"; "Capitalism in the New Millenniwn: The Challenge of Sustainability"; "The Future of the Systems Sciences"; "Global Issues in the New Millenniwn"; "Resources and the Environment in the New Millenniwn"; "The Lessons of Y2K"; and "Can There be a Reconciliation Between Science and Religion?" Included in this special commemorative volume is a cross-section of these presentations.
