12. Zachman 13. Zachman

  • Classified by basic 6 wh questions
    • When, where, why, who, what how
    • No predefined order
  • Work on 5 layers
    • Scope, Enterprise model, system model, technology, components.
  • Any cell should be defined.
  • The more the relationships between cross cells and layers are defined, the better.
  • Must obey the framework rules!

14. Zachman

  • Rules:
    • The columns have no order
    • Each column has a simple, basic model
    • The basic model for each column must be unique
    • Each row represent distinct, unique perspective
    • Each cell is unique
    • Integration of all row cells constitutes complete row picture.
    • The logic is recursive
