Zachman
The EA rush / Natty Gur13 INCOSE_IL 2005
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!
The EA rush / Natty Gur14 INCOSE_IL 2005
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
