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

The Zachman Framework uses a 36‑cell matrix to help organizations structure and understand their enterprise architecture and IT assets. Developed by John Zachman in 1987, it serves as an ontology rather than a strict methodology, enabling architects to organize documents, specifications, and models.

The matrix consists of six rows representing stakeholder viewpoints (Planner, Owner, Designer, Engineer, Technician, User) and six columns representing fundamental questions (What, How, Where, Who, When, Why). Each cell captures unique information about processes, data, locations, people, timing, and motivations.

The framework’s rules emphasize that columns have no inherent order, each column has a generic model with its own meta‑model, models must be unique, rows describe distinct perspectives, and the matrix should avoid redundancy. Following these principles ensures each cell provides a singular, detailed view of the architecture.

Training and certification are offered by Zachman International through hands‑on workshops, allowing participants to apply the framework to real‑world scenarios and learn implementation techniques.
