UML and business modeling
UML (industrial standard)

business modeling (first phase in IS development)
language for business modeling

• PRO
• 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

• CONTRA
• traditional techniques and notations are more
  popular

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 use case model
• business object model

(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.

• Business object model
• 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.

• BUC model also contains realization descriptions
  of identified BUCs. We can document realization
• textually, and
• graphically (high level activity diagram)

activity diagram.

Business object model

• Business object model includes
• detailed activity diagrams,
• interaction diagrams, and
• object diagrams.
• Detailed activity diagram
• high level activity diagram completed by workers'
  responsibilities, used objects and object
  flows
• Responsibility areas of involved workers are
  emphasized by swimlanes
• activity diagram is procedurally (algorithmic)
  oriented and its not appropriate for
  OO AD

diagram.

Business object model (continued)

• business object model also includes
• business object (class) diagram
• shows the static structure and
• relationships between objects
• can be used to show organization
• structure of business system

• 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-gtmethods
• during the system class diagram
  development

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
  Foreigners Migration System implemented for
  government institutions in BosniaHerzegovina.
