PROPRO

during the whole cycle of IS development, from business modeling to software implementation and transition in business domain, harmonized notation will be used

transition from business models to system UML models will be easier

possibilities for extending, adopting and specialization of standard UML

Business model by UML business profile

Profile - defined set of standard language extensions, built in UML, and specialized for modeling in particular domain.

Business profile (v1.3) specializes base classes of standard UML by introduction of business domain specific classes.

Business model = two models

Business model by UML business profile (continued)

Business use case model

Outside view of business system

describes business system and its relationships with the exterior systems through the BUCs.

BUC is the business process, or some concrete function in business system offered to the exterior systems. BUC is the sequence of actions, preformed by workers in business system, and by them business system makes some concrete and recognable value.

Exterior systems are called business actors.


Inside view of business system

in the completeness shows process, procedures, business worker's behaviour, used resources (business objects) and their relationships and organization, that goals can be realized and expected results achieved

Business use case model

BUC model contains descriptions of business actors and BUCs and their interactions, represented by BUC diagrams.

Business object model includes:

detailed activity diagrams, interaction diagrams, and object diagrams.

completed by workers' responsibilities, used objects and object flows

Responsibility areas of involved workers are emphasized by swimlanes

Business object model (continued)

business object model also includes some of OO interaction diagrams:

collaboration diagram (process’ structure)

sequence diagram• focus on temporal component of process • easy mapping messages->methods

includes business object (class)

Transition from business models to system models

Identified BUCs, business actors, business workers and business objects can be used in transition from business models to initial system models.

BUC model is transferred in the system UC model, and business object model is transferred in the system design model.

Next rules are valid during transition from BUC model to system UC model:

each BUC is candidate for system UC, each business actor is possible system

actor, each worker is possible system actor.

During the transition of business object model next rules are valid:

each identified entity (worker or business object) is possible system class, and

each message in sequence diagram is possible method of system class.

Conclusion

Although primary intended for visual modeling of software systems, thanks to business profile, UML can be successfully used for business modeling too.

Thanks to very rich notation and semantics, UML business profile offers possibilities for all business domain analysis' aspects.

UML based business modeling has especial importance if it's base for IS development. Then, notations for business modeling and system modeling are harmonized, and used concepts offer possibilities for easy transfer business models to system UML models.

Described approach of business modeling is illustrated by some parts of business model of Foreigner’s Migration System implemented for government institutions in Bosnia&Herzegovina.
