• individuals who put the tools and principles of systems thinking into practice every day in their workplaces, neighborhoods, and families;
• organizational development professionals and consultants who continually use and develop these tools and principles in their work with organizations
• researchers who constantly refine and deepen our understanding of systemic behavior;
• software firms that create the tools that make systems thinking simulations and "microworld" practice fields possible; and
• teachers and administrators from elementary up through graduate-school levels who are re-imagining education and introducing new generations of students to the field.

The community is also international—as word of the power of systems thinking has spread, more and more organizations worldwide are putting that power to use. These far-flung organizations are astonishingly diverse, ranging from the police department in Singapore to The Boeing Company in the United States and from universities in Great Britain to consulting firms in South America. Clearly, the field speaks to some universal, enduring values and concerns that organizations of all shapes and sizes resonate with.

Each member of this widespread community contributes to it in unique ways. At Pegasus, we try to be "good citizens" by providing educational and training resources electronically and in print, conferences and other learning events, and audio and video recordings that bring you the latest thinking and insights from the field. Through our conferences, we provide opportunities for the many diverse members of this special community to come together. And as technologies and organizational challenges change, we design ever more innovative ways to help you put systems thinking to work in your own life.

From individuals, to organizations, to communities—systems thinking comes to life on all three of these levels. The years ahead will prove very exciting, as this worldwide community both broadens and deepens, and as people from around the world come together in new ways to address the most pressing challenges of our time.
