Integrating the material in several earlier books, this book explains how complexity can be resolved by the use of processes that are designed in the full light of two sets of scientific literature:

The literature on formal logic: (Aristotle, Abelard, De Morgan, Boole, Peirce, Harary, Warfield)

The literature on behavioral pathologies of individual, groups, and organizations: (Alberts, Allison, Argyris, Bales, Boulding, Cardenas, Downs, Foucault, Janis, Lasswell, Miller, Simon, Tuckman, Warfield)

The book shows how processes that incorporate the research results from these two literatures have been applied repeatedly in government, industry, religion, and universities to resolve complexity. Specific instances of successful applications of Systems Science are described in detail.

The concept of complexity is interpreted comprehensively. Various metrics of complexity are defined, modes of computing their values are given and values from applications are shown. Dr Warfield presents the Twenty Laws of Complexity that he has compiled, explaining their use in organizations. Warfield explains how commonly-made assumptions prevent resolution of complexity. The book contains numerous drawings and tables and provides a detailed index.

In Warfield's 1976 book titled Societal Systems: Planning, Policy, and Complexity, published by Wiley Interscience Systems Engineering Series (Harold Chestnut, Editor), he presented an integrated sequence of chapters on what he has since labeled as "the mathematics of structure". It was in this book that he introduced a computer-assisted group process called "Interpretive Structural Modeling."

The mathematics that provided the basis of concepts presented in Societal Systems were inadvertently camouflaged by residing within the larger text; therefore, Warfield decided to extract this information and publish The Mathematics of Structure as a separate text in the year 2003.

Chapter titles:

  • Boolean Algebra, Sets, and Binary Relations
  • Binary Matrices and Matrix Models
  • Digraphs, Digraph Maps, and Digraph Models
  • Structure and Complexity
  • Cycles
  • Interpretive Structural Modeling (ISM)

Within the first three chapters, this book offers the foundational mathematics of structure.

The last three chapters show how computer-assisted model construction can assist in taking advantage of the aggregated and integrated beliefs of well-informed (and partially-informed) groups of actors (meaning individuals taking action).

The middle chapter, "Structure and Complexity," explains how applications of the mathematics of structure enable insights to be developed about problematic situations - insights that will not be discovered using methods that are less scientific.

This is the first book that renders a thorough discussion of systems science. It draws on material from an extensive collection of external sources, including several other books and a special library collection complete with videotape empirical evidence of applicability of the theory to a wide variety of circumstances. This is essential because systems science must be responsive to diverse human situations of the widest difficulty, and it must fill the void that the specific sciences cannot fill, because these sciences are insensitive to the necessities of reconciling disparate views of multiple observers, and incorporating local conditions in hypotheses that precede inductive explorations.











With minor exceptions, this collection of PDFs contains the material in the second edition of the following book:

J.N. Warfield and A.R. Cardenas (1994), A HANDBOOK OF INTERACTIVE MANAGEMENT, 2ND Ed., Ames, IA: The Iowa State University Press (ISBN 0-8138-2407-9).

Because this book is now out of print, the original manuscript is available for free download in PDF format. The book contains about 350 pages in 8.5 X 11 inch format, which accommodates quite a few detailed drawings. Included in the scanned files are: are short preface, a list of figures, a list of tables, a bibliography, an index to topics, an index to names, and an index to organizations.

Chapter Titles:

  • What is Interactive Management?
  • Interactive Management Outcomes
  • Interactive Management Success Levels
  • Interactive Management Roles
  • Interactive Management Products (Application Structural Types)
  • Interactive Management Processed
  • Demosophia Facility (Situation Room for Interactive Management)
  • Interactive Management Software
  • Interactive Management Planning Phase (Phase 1)
  • Interactive Management Workshop Phase (Phase 2)
  • Interactive Management Follow-Up Phase (Phase 3)

John N. Warfield

Welcome to The Warfield IP Trust 

Our goal is to ensure the John N. Warfield intellectual legacy remains widely available.


Our Catalog of Dr. Warfield’s work includes almost 2,000 books, videos, presentations and published and unpublished papers. Many will soon be available for download here. Registered visitors on this site will be notified when the site is updated. 


Dr. Warfield did much of his later work at George Mason University in Fairfax, Virginia, USA. He later donated the originals of many of his documents to GMU's Special Collections and Archives. The collection is cataloged for online review and is open to visitors.


John Warfield: Scientist, Inventor and Teacher

Dr. Warfield is best known as the inventor of Interpretive Structural Modeling (ISM), Interactive Management and Generic Design Science.
Interactive Management and ISM software have been applied by practitioners around the globe to large-scale, difficult problems in industry and government, ranging from automotive design at Ford, to DoD procurement, to government policy at every level.

In Understanding Complexity: Thought and Behavior, Dr. Warfield defined Interactive Management as "a system of management invented explicitly to apply to the management of complexity. It is intended to be applied intermittently in organizations to enable those organizations to cope with issues or situations whose scope is beyond that of the normal type of problem that can readily be solved."
During his distinguished career, Dr. Warfield published five books and more than 100 papers on topics including computers, software, systems, organizations, electrical networks, Interactive Management and generic design science.


Likely part of an intended book manuscript. Discusses Warfield’s economic research and the ways in which Interpretive Structural Modeling could assist international organizations operate more effectively. See also, “Principal Subsystems (Dimensions) and Legacy Organizational Structures.”

Multiple documents are associated with this number. Collection of materials for paper Warfield planned to write to discuss the next stage beyond Interactive Management, a stage of management which he had termed Work Program of Complexity Includes a comparison between Interactive Management and the Work Program of Complexity, an outline of Warfield’s 3 February 2004 Presentation “The Work Program of Complexity,” and a description of 14 tangible and 5 intangible results a corporation could expect from using Warfield’s Work Program of Complexity when trying to manage a difficult situation.

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

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.
