Characteristics
The OBASHI Methodology models the enterprise/an organisation in six horizontal layers. The layers provide a framework (the OBASHI framework) for organising individual elements that represent individual Business or IT assets and resources. The layers are:
- Ownership
- Business Process
- Application
- System
- Hardware
- Infrastructure
Placing the elements above or below each other within the framework signifies a relationship between the elements. For example, placing an Owner element above a Business Process element signifies that the business processes belongs to that owner. Placing a business function above an application signifies that the process uses that application etc...
Elements can be connected on the diagram to denote a physical relationship, such as the connection between a hardware element and an infrastructure element. Dependencies can also be documented on the diagram to show explicit non-obvious relationships between elements, such as the reliance of a business process on a third party resource.
Each element can be referenced to supporting documentation to provide a supporting context for that element.
The flow of data (dataflows) can be superimposed on the diagrams to depict a sequence of elements required to support a business service.
The combination of one or more OBASHI diagrams form a contextual model for analysis.
