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

15
The TOGAF way

• Never ending organization process which builds
  upon several stages
• Initiation
• Business architecture.
• Information architecture
• Applications architecture
• Infrastructure architecture
• Governance
• Gap analysis
• And again
