What Is the Zachman Framework? An Overview of Its Matrix, Rows, Columns, Rules, and Training

The Zachman Framework uses a 36‑cell matrix to help organizations structure their enterprise architecture and gain deep insight into IT assets.

It is not a methodology but an ontology or pattern that assists architects in organizing artifacts such as documents, specifications, and models, considering stakeholders like owners and aligning them with the problems being addressed.

Developed by IBM’s John Zachman in 1987, the framework has been updated repeatedly to organize and analyze data, solve problems, plan the future, manage enterprise architecture, and create analytical models. Its relevance persists today because modern technology environments are increasingly complex, with legacy systems and dispersed information that can hinder agility; the 36‑cell matrix enables comprehensive classification of all architectural aspects, helping organizations stay flexible amid change.

Zachman Framework Template

The template consists of 36 categories describing anything from products and services to hardware and software, arranged in six rows and six columns to form a two‑dimensional matrix that visualizes topics, problems, or products.

Columns pose fundamental questions (who, what, where, etc.), while rows represent the viewpoints of different stakeholder types. Each cell is populated with processes, required materials, key roles, relevant locations, and any goals or rules associated with the project.

Six Rows (Stakeholder Perspectives)

Planner’s View (Scope): Determines business plans or strategies and defines which issues the matrix will address.

Owner’s View (Business Concept): Identifies business needs and the resources required for execution.

Designer’s View (System Logic): Describes how the plan will satisfy business needs, focusing on data, processes, and functions.

Engineer’s View (Technology Physical): Details implementation choices, tools, technologies, materials, and constraints.

Technician’s View (Component Assembly): Captures requirements for products, services, or hardware.

User View (Operations): Provides information on how the functional system works within the IT or business environment.

Six Columns (Fundamental Questions)

What (Data): Defines the business data, information, and requirements needed.

How (Function): Describes how processes work and affect the business.

Where (Network): Lists the system networks and locations where business operations occur.

Who (People): Identifies key stakeholders and all personnel involved.

When (Time): Determines when and where business processes are executed.

Why (Motivation): Explains the reasons behind chosen solutions and the initiative’s driving forces.

Zachman Framework Rules

Columns have no inherent order but should be arranged from the most important category downward.

Each column has a simple generic model and may possess its own meta‑model.

The basic model of each column must be unique, avoiding overlap or duplication.

Each row describes a distinct perspective; meta‑models or concepts should not be assigned to multiple cells.

If rules 2‑4 are followed, every cell in the matrix will be unique, providing a detailed, information‑rich view.

Avoid changing the names of rows or columns to prevent confusion.

The logic is recursive and generic, allowing classification or analysis of any content related to the discussed enterprise architecture.

Training and Certification

The Zachman Framework offers a strict two‑dimensional matrix structure that enables organizations to develop solutions for identified problems across the 36 cells. Zachman International provides official training and certification, including a four‑day hands‑on modeling workshop where participants see real‑world examples, learn to build and implement original models, and acquire tools and methods to support framework adoption.
