Enterprise Information
Connectivity Modeling: The business architecture model should encapsulate the connectivity between mission, function, information, organization, location and demand. The business architecture model should also capture the connectivity between organization, location and demand.

What is enterprise business architecture?
1. Business Architecture define the EnterpriseEnterprise Business architecture is a high level enterprise business definition. It describe and define the entire enterprise to see the whole rather then the business architecture for a specific area as described in application development.
1.1 Business Architecture serve both business and engineering community
Traditional business architecture analysis has focused on the engineering aspect of structure and connectivity. However, business community's concern in business architecture is from the aspect of business outcome rather than from the business structure.
1.2 Enterprise Business Architecture is wide and thin
The Enterprise Business Architecture serve as the business master plan is light and notional to see the big picture and over come the risk of "paralysis by analysis" based the different level of architecture effort in the following figure. Under the umbrella of the enterprise business architecture master plan, the segment architecture effort elaborate the business architecture plan for the specific area and the solution architecture further detail the business architecture for the specific project.
2. ENTERPRISE BUSINESS ARCHITECTURE MODEL
The Enterprise Business Architecture model suggest to define an enterprise from the aspect of Mission (Why), Function(What), Process(How), Organization(Who), Location(Where) and Worklaod(When).
3. Business Architecture is not business process centric
the solution architecture domain, which focuses on automation, is all about business processes. LEA defines the holistic business architecture from an enterprise’s business mission, function, information, organization, location and demand. One thing to notice is that process is not part of the attributes in defining the enterprise. It is merely consider as the connectivity between functions. It is important to clarify that business process are the means to achieve business goal, not the means to defining the enterprise.
3.1 Business process are considered as the function connectivity
From the holistic business architecture, business processes are consider as the function connectivity. Business process is not an enterprise definition, it is a mean to achieve business mission. It subject to reengineering to take advantage of technology evolution, it also subject to localization for local need.
4. A holistic business architecture framework
LEA apply the holistic framework to analyze business architecture. It is composed based on the business architecture attributes of Mission, Function, Information , People, Location and Workload and the type of Business Architecture Analysis which include Structure, Connectivity and Influence as shown in the following figure.
4.1 Structure modeling :
Structure analysis has been the most popular modeling practice The popular function decomposition diagram is the function structure, data entity modeling is the data structure, organization chart is the organization structure. The Business architecture modeling must also include the location and demand.
The buisiness function decomposition diagram.
4.2 Connectivity Modeling
Business architecture model the connectivity on mission, function, information, organization, location and demand. The popular Business process modeling is the function connectivity, Data flow modeling is the data connectivity. Business architecture also have to model the connectivity on organization, location and demand.
The relation between the business architecture attributes. It is a network graph representation
4.3 Influence diagram modeling
To support business community need, the Holistic Business Architecture incorporate high level Influence Diagram[1], Business community concerns more on the influence between enterprise component for decision making. Business community have use influence diagram for many year to support decision making. It include the influence on mission, function, information, organization, location and demand.
Business Community which is mission outcome orietned, do not view business from the aspect of structure and connectivity as the engineering do. They concerns more from the aspect of capability and influence. They look at the business from the aspect of outcome interm of "For" and "Againt". The business community has developed the "Influence Diagram"
The business community is more concerned with the influences between enterprise components when it comes to decision making. The business community has utilized influence diagrams for many years to support decision making, as they show the influence that mission, function, information, organization, location and demand have on each other.

1.1 Business Architecture Analysis
1.2 Analyze based on the business architecture model and their relationship
The business architecture model describe what is the business architecture. EA must take the enterprise definition of the enterprise organization, location, demographic and workload distribution into account. However, most of the enterprise architecture approach have over looked the enterprise definition. The traditional EA approach consider the enterprises definition as the operational characteristic for each application systems. The LEA approach articulate the product definition and the enterprise definition to define the engineering of sharing and the engineering of reuse and establish the Practical Enterprise Architecture model.
