Describing an Enterprise Architecture

A transformation stage is defined by a number of components that represent its architecture. This consists of:
• The lists of exhibited business capabilities;

An exhibited business capability is exhibited by an Enterprise Stage with quantified measure (KPI) and potential geopolitical scope (Site) for a defined market segment (Business Partner).
• the business architecture environment;

A business architecture environment represents the relationships of a business functional area with its partners.
• the solution building block environments.
Describing the operating architecture
The business architecture environment contains the elements that define the enterprise model (operational model) for the current stage.
The elements constituting the enterprise operational model are:
• the enterprise ecosystem defined by the service interactions with the partners,
• the business function architectures,
• the business functions.
