The Zachman Framework™ is a schema — the intersection between two historical classifications that have been in use for literally thousands of years.  The first is the fundamentals of communication found in the primitive interrogatives:  What, How, When, Who, Where, and Why.  It is the integration of answers to these questions that enables the comprehensive, composite description of complex ideas.  The second is derived from reification, the transformation of an abstract idea into an instantiation that was initially postulated by ancient Greek philosophers and is labeled in The Zachman Framework™:  Identification, Definition, Representation, Specification, Configuration, and Instantiation.[1]

Since The Zachman Framework™ classification was observed empirically in the structure of the descriptive representations (the architecture) of buildings, airplanes, and other complex industrial products, there is substantial evidence to establish that The Zachman Framework™ is the fundamental structure for Enterprise Architecture and thereby yields the total set of descriptive representations relevant for describing an Enterprise.

The Zachman Framework™ typically is depicted as a bounded 6 x 6 "matrix" with the Communication Interrogatives as Columns and the Reification Transformations as Rows.[2]  The Framework classifications are represented by the Cells — that is, the intersection between the Interrogatives and the Transformations.  This matrix would necessarily constitute the total set of descriptive representations that are relevant for describing something ... anything — in particular an enterprise.

More specifically, The Zachman Framework™ is an ontology — a theory of the existence of a structured set of essential components of an object for which explicit expressions is necessary and perhaps even mandatory for creating, operating, and changing the object (the object being an Enterprise, a department, a value chain, a "sliver," a solution, a project, an airplane, a building, a product, a profession, or whatever or whatever).

The Zachman Framework™ IS NOT a methodology for creating the implementation (an instantiation) of the object.  The Framework IS the ontology for describing the Enterprise.  The Framework (ontology) is a STRUCTURE whereas a methodology is a PROCESS.  A Structure is NOT a Process.  A Structure establishes definition whereas a Process provides Transformation.

Processes based on ontological structure will be predictable and produce repeatable results (for example, Chemistry, based on the Periodic Table).

Conversely, Processes without ontological structures are ad hoc, fixed, and dependent on practitioner skills (for example, Alchemy, based on trial and error).

The Zachman Framework™ is a metamodel and, unlike a methodology, does not imply anything about:

  1. Whether you do Architecture or whether you simply build implementations — that is, whether you build Primitive Models (the ontological, single-variable intersections between the Interrogatives and the Transformations) or whether you simply build ad hoc, multi-variable, composite models made up of components of several Primitive Models.

  2. How you do Architecture:  top-down, bottom-up, left to right, right to left, where to start, etc., etc.

  3. The long-term/short-term trade-off relative to instantiating the expression of the components of the object — that is, what is formalized in the short-term for implementation purposes versus what is engineered for long-term reuse.

  4. How much flexibility you want for producing composite models (Enterprise implementations) from your Enterprise Architecture (primitive models) — that is, how constrained (little flexibility) or unconstrained (much flexibility) you make the horizontal, integrative relationships between the Cell components across the Rows and the vertical, transformational relationships of the Cell components down the Columns.

  5. Although these are significant, identifiable, methodological choices, they are not prescriptions of The Framework structure.

The Zachman Framework™ is the basis for Architecture — We know what architecture is for industrial products (buildings, airplanes, locomotives, computers, etc., etc.) because in the Industrial Age, it was the industrial products that were increasing in complexity and the industrial products that were changing.  If we had not gotten extremely sophisticated relative to architecture for industrial products, we would not likely be able to create and change complex industrial products and we would likely still be in the Industrial Age learning about Product Architecture.

Now that we are in the Information Age, it is the Enterprise that is increasing in complexity and the Enterprise that is changing.  It is my opinion that Enterprise Architecture is the determinant of survival in the Information Age.  Therefore, The Framework for Enterprise ArchitectureThe Zachman Framework™ — has some profound significance in putting definition around Enterprise Architecture, the survival issue of the Century.  We have yet a LOT to learn about Enterprise Architecture, but I submit, The Zachman Framework™ would be a good place to start.

John A. Zachman is the originator of the "Framework for Enterprise Architecture" (The Zachman Framework™) which has received broad acceptance around the world as an integrative framework, an ontology for descriptive representations for Enterprises.

Mr. Zachman is not only known for this work on Enterprise Architecture, but is also known for his early contributions to IBM's Information Strategy methodology (Business Systems Planning) as well as to their Executive team planning techniques (Intensive Planning). He served IBM for 26 years, retiring in 1990 to devote his life to the science of Enterprise Architecture.

Mr. Zachman is the Founder and Chairman of his own education and consulting business, Zachman International®. He is also Founder of the Zachman Institute™, a nonprofit organization devoted to leveraging Zachman International's vast network of professionals and resources to offer services to small businesses and nonprofit organizations as they prepare for and experience growth.

Mr. Zachman serves on the Executive Council for Information Management and Technology (ECIMT) of the United States Government Accountability Office (GAO) and on the Advisory Board of the Data Administration Management Association International (DAMAI) from whom he was awarded the 2002 Lifetime Achievement Award. He was awarded the 2009 Enterprise Architecture Professional Lifetime Achievement Award from the Center for Advancement of the Enterprise Architecture Profession as well as the 2004 Oakland University, Applied Technology in Business (ATIB), Award for IS Excellence and Innovation.

Mr. Zachman has been focusing on Enterprise Architecture since 1970 and has written extensively on the subject. He has facilitated innumerable executive team planning sessions. He travels nationally and internationally, teaching and consulting, and is a popular conference speaker, known for his motivating messages on Enterprise Architecture issues. He has spoken to many thousands of enterprise managers and information professionals on every continent.

In addition to his professional activities, Mr. Zachman serves on the Elder Council of the Church on the Way (First Foursquare Church of Van Nuys, California), the Board of Directors of Living Way Ministries, a radio and television ministry of the Church on the Way, the President's Cabinet of The King's University, the Board of Directors of the Los Angeles Citywide Children's Christian Choir, the Board of Directors of Heavenworks, an international ministry to the French speaking world and on the Board of Directors of Native Hope International, a Los Angeles based ministry to the Native American people.

Prior to joining IBM, Mr. Zachman served as a line officer in the United States Navy and is a retired Commander in the U. S. Naval Reserve. He chaired a panel on "Planning, Development and Maintenance Tools and Methods Integration" for the U. S. National Institute of Standards and Technology. He holds a degree in Chemistry from Northwestern University, has taught at Tufts University, has served on the Board of Councilors for the School of Library and Information Management at the University of Southern California, as a Special Advisor to the School of Library and Information Management at Emporia State University, on the Advisory Council to the School of Library and Information Management at Dominican University and on the Advisory Board for the Data Resource Management Program at the University of Washington. He has been a Fellow for the College of Business Administration of the University of North Texas and currently is listed in Cambridge Who's Who.
