Phase B - Business Architecture

The Location catalogue provides a listing of all locations where an enterprise carries out business operations or houses architecturally relevant assets, such as data centers or end-user computing equipment. Maintaining a definitive list of locations allows change initiatives to quickly define a location scope and to test for completeness when assessing current landscapes or proposed target solutions.

The purpose of the Functional Decomposition diagram is to show on a single page the capabilities of an organization that are relevant to the consideration of an architecture. By examining the capabilities of an organization from a functional perspective, it is possible to quickly develop models of what the organization does without being dragged into extended debate on how the organization does it. Once a basic Functional Decomposition diagram has been developed, it becomes possible to layer heat maps on top of this diagram to show scope and decisions.

The purpose of the Role catalog is to provide a listing of all authorization levels or zones within an enterprise.

The Contract/Measure catalog provides a listing of all agreed service contracts and the measures attached to those contracts. It forms the master list of service levels agreed to across the enterprise. The Contract/Measure catalog contains the following metamodel entities: Business Service Application Service (optionally) Contract Measure

The purpose of this matrix is to show which actors perform which roles, supporting definition of security and skills requirements. Understanding Actor-to-Role relationships is a key supporting tool in definition of training needs, user security settings, and organizational change management. The Actor/Role matrix shows the following metamodel entities and relationships: Actor Role Actor performs Role relationships

The Business Service/Information diagram shows the information needed to support one or more business services.

The purpose of the Business Service/Function catalog is to provide a functional decomposition in a form that can be filtered, reported on, and queried, as a supplement to graphical Functional Decomposition diagrams. The Business Service/Function catalog can be used to identify capabilities of an organization and to understand the level that governance is applied to the functions of an organization.

The purpose of the Process Flow diagram is to depict all models and mappings related to the process metamodel entity.

Process Flow diagrams show sequential flow of control between activities and may utilize swim-lane techniques to represent ownership and realization of process steps. For example, the application that supports a process step may be shown as a swim-lane.

An Organization Decomposition diagram describes the links between actor, roles, and location within an organization tree. An organization map should provide a chain of command of owners and decision-makers in the organization. Although it is not the intent of the Organization Decomposition diagram to link goal to organization, it should be possible to intuitively link the goals to the stakeholders from the Organization Decomposition diagram.

A Business Footprint diagram describes the links between business goals, organizational units, business functions, and services, and maps these functions to the technical components delivering the required capability. A Business Footprint diagram provides a clear traceability between a technical component and the business goal that it satisfies, while also demonstrating ownership of the services identified. A Business Footprint diagram demonstrates only the key facts linking organization unit functions to delivery services and is utilized as a communication platform for senior-level (C
