Cycoda: RUP Business Model

The purposes of the Business Modelling discipline are:

To understand the structure and the dynamics of the organisation in which a system is to be deployed (the target organisation).
To understand current problems in the target organisation and identify improvement potentials.
To ensure that customers, end users, and developers have a common understanding of the target organisation.
To derive the system requirements needed to support the target organisation.

To achieve these goals, the business modelling discipline describes how to develop a vision of the new target organisation, and based on this vision define the processes, roles, and responsibilities of that organisation in a business use-case model and a business object model.

Complementary to these models, the following artefacts are developed:
