In this third installment of understanding the Zachman Framework, we will be diving into the Column Aspects. Additionally, I will conclude my thoughts on the framework and share some key benefits of using the framework overall.
The Zachman Framework is often visualized as a two-dimensional matrix consisting of six rows and six columns. Each cell within the matrix represents a different aspect of the enterprise architecture, ensuring a holistic view. The rows correspond to different perspectives or viewpoints of various stakeholders within an organization, while the columns correspond to different aspects of the enterprise that need to be addressed.
Elements of the Zachman Framework
