EA frameworks

• Reference model– How to do certain tasks.– Not an outcome!

• Zachman, FEAF, TOGAF, other sector oriented.

• They’re all adjustable to your needs.

Zachman

Page 13: The EA rush / Natty Gur

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!

Page 14: The EA rush / Natty Gur

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

Page 15: The EA rush / Natty Gur

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 …
