We start by agreeing a Statement of Business Objectives to establish the scope of the Enterprise Data Model.
Once we have agreed the Statement of Business Objectives we can create a draft Top-Level Model with associated Subject Areas, each of which is shown in its own Model.
This is an example of a Statement of Business Objectives for a Retail organization :-
"Our Business objectives are to offer a wide range of affordable Products.
We will control costs to achieve maximum profit potential from a wide range of affordable Products which are sourced
on a 'just-in-time' basis tailored to our target market, with specific Customer profiles.
The Enterprise Data Model will establish the data available for a Data Warehouse to meet Business Intelligence requirements."
