Zachman Framework
53
Zachman Framework
The Zachman Framework is a matrix that provides a structured approach to organizing and understanding an enterprise's architecture. The framework consists of six columns and six rows that intersect to form a grid. Each cell in the grid represents a different perspective on the enterprise, and each perspective provides a unique view of the enterprise's architecture.
54
Zachman Framework
55
Zachman Framework
In this example, the six columns represent different aspects of an enterprise's architecture: What (data), How (function), Where (environment), Who (actors), When (cycle), and Why (purpose). The six rows represent different perspectives on the enterprise: Planner, Owner, Designer, Builder, Subcontractor, and User.
56
Zachman Framework
Each cell in the grid represents a unique combination of a perspective and a perspective on the enterprise. For example, the cell in the Planner column and the What row represents the perspective of a planner looking at the enterprise's data. The cell in the Designer column and the How row represents the perspective of a designer looking at the enterprise's functions.
57
Zachman Framework
By analyzing each cell in the grid, an enterprise can gain a better understanding of its architecture from multiple perspectives. This can help the enterprise identify areas for improvement, streamline processes, and achieve its goals and objectives.
58
