Warfield's final book was left as a full draft manuscript. It is now being edited and prepared for publication.

This book is in some ways a summary and refinement of his life's studies, whittling out topics and ideas that he felt were no longer essential and restating ideas he felt to be basic for future establishment of Systems Science as a verifiable academic discipline.

Warfield had begun to support only two primary methodologies: NGT (Nominal Group Technique) and ISM (Interpretive Structural Modeling), relegating others as redundant or subsidiary.


An Introduction to Systems Science - 2006

Written in layman’s terms, this book is an effort to establish an understanding of the new field of Systems Science including its foundations in the thinking of earliest philosophers, identification of some modern day practitioners and a description of the processes and working environment needed for its application.

To engage with those new to the field, it avoids large, complex graphics and mathematics, and is meant to lead the reader to more detailed works.


The Mathematics of Structure - 2003

Augmented by a 2-page introductory Preface written in November 2002, The Mathematics of Structure consists of Chapters 8 to 14 of Warfield's Societal Systems.

The book focuses on the mathematics behind Interpretive Structural Modeling (ISM). It is an enlargement of an IASIS Report printed in 1997 which contained only three chapters. Figures were copied from Societal Systems. 


This third edition of A Science of Generic Design from AJAR Publishing is in two volumes. It is a reproduction of the one-volume 1994 Second Edition issued by Iowa State University Press. It has been produced in response to demand from those who have been unable to get the hard cover 1994 edition from other sources since it has gone out of print.

This book explains a new science Warfield developed between 1970 and 2000. His Interactive Management system is the action branch of systems science, which springs from the foundations of a scientific theory outlined in this book.

The book began as a set of lectures, classroom handouts, seminars and small monographs organized in 1995 into a manuscript titled “Work Program of Complexity.”

In 1998, after an extensive revision with much new material added, Warfield changed the title to “A Structure Based Science of Complexity.” After a few more modifications until June 2001 he finalized the title as Understanding Complexity: Thought and Behavior.


A Handbook of Interactive Management, 2nd edition - 1994

Co-written by John N. Warfield and A. Roxana Cardenas.

A user's guide for clients as well as practitioners, this volume itemizes essential methods and equipment needed to apply Interactive Management in a way that meets the standards envisioned by Warfield when he invented it.

The handbook includes a discussion of software as well as consensus methodologies. This volume contains three indexes and a list of then-current qualified Interactive Management practitioners.



Societal Systems describes a unique methodology for coping with complexity - Interpretive Structural Modeling.

ISM, with its efficient and rapid organization of knowledge, can become the basis for modeling dramatic social or organizational gains.

The book contains the theoretical and mathematical background for the ISM process, which remains in use as a major source for persons wishing to develop software for Interpretive Structural Modeling. A modern version of ISM software is available on this site.

Ajar Publishing is working on a corrected reprint of Societal Systems that may be available in 2019.
