The purpose of the Business Design Model is to describe how the business use cases are realized. The Business Design Model defines the services offered by the business in terms of interfaces and operations, the information that is passed around (business entities), the internal organization into business systems and business workers and how they collaborate to realize the external behavior described in the business use cases.

This is the place where all the design decisions are captured. The "more abstract" elements from the Business Analysis Model are realized by "more concrete" ones. For example, the initial Business Workers are mapped or realized into human workers or automated systems. In most of the cases the Business Analysis Model evolves into a Business Design Model, as more design decisions are taken.

The Business Design Model is used by stakeholders, business-process analysts and business architects to understand how the business currently works (in as-is form), and to analyze the effect of changes to the business (in to-be form). The business architect is responsible for the structure and integrity of the model, while business designers are responsible for detailing elements within the model. The model is also used by systems analysts for deriving system requirements based on how automated systems - that is, automated business workers (usually software-intensive) - will be used as part of business processes. Software architects use the model to define a software architecture that fits the organization seamlessly and to identify classes in software analysis and design models.

As in the business analysis model case, the business design model describes how the business works internally to perform business functions, so the model is essential when considering changes to the business processes or the organization (structure, roles and responsibilities) - you will be unable to reason about such changes without this model.

Опции представления

UML Representation:  Model, stereotyped as <<business design>>.

The business design model may have the following properties, similar to the Business Analysis Model:

  • Introduction: A textual description that serves as a brief introduction to the model.
  • Business Systems: Components in the model, representing a hierarchy*.
  • Business Workers: The Business Worker classes in the model, owned by the Business Systems.
  • Business Entities: The Business Entity classes in the model, owned by the Business Systems.
  • Business Events: The Business Event classes in the model, owned by the Business Systems.
  • Business Rules: The Business Rules captured in the model. These are not the Business Rules that are captured in document form in a separate artifact.
  • Relationships: The relationships in the model, owned by the Business Systems.
  • Business Use-Case Realizations: The Business Use-Case Realizations in the model, owned by the Business Systems.
  • Business Context Collaboration: The external realization of the interactions between the business and the business actors, showing the services provided by the top-level Business System (that is, the business itself), the interfaces for these services, the connections to the business actors, and the Business Entities input and output.
  • Diagrams: The diagrams in the model, owned by the Business Systems.

*Note that the business itself is the top-level component (Business System), and may directly encapsulate business workers, business entities etc.
