How to start describing business (architecture)

- Use IBM's CBM method and generic industry CBM to identify the business components (business functions) -- identify three cases for components:
- that match fully (exist in generic industry CBM),
- that match partially, and
- are missing from generic industry CBM.
- Map the resulting business components to the existing organizational structure (verify this mapping with the responsibility descriptions of organizational units)
- Define the externalboundary (interface) of business system(s) -- identify:
- the service types delivered/produced and
- the service types required/consumed to both external and internal customers.
- Map the resulting service types to the business components.
- Consolidate/split business components (business functions) not depending on the existing organizational structure, but depending on the coupling between components (functions).
- Define the used/planned business model(s) by defining (according to Osterwalder's method):
- customer segments (types)
- value offerings (products) -- packages of the predefined services deliverable to the customer segments
- Delivered service types on the external boundary (interface) identify the primary business processes, needed to produce services.
- If primary business processes are identified, then describe these on very high level -- not yet even the diagram of activities, but inputs, outputs, performers, material resources used/needed, purpose, dependencies, etc. (for example using SIPOC).
- Supporting business processes could be then identified from:
- the (human and material) resources needed for primary processes -- resources need to be managed, and
- the primary and supporting business processes themselves-- processes also need to be managed (planning and controlling).
