Classification of Processes
partly translated from (Gadatsch 2005, S. 44)
structured
process
case ad hoc process
• structured process
flow
• many repetitive
elements
• no degrees of
freedom for people
• process flow can
partly be structured
• some repetitive
elements
• degrees of freedom
for people
• process flow cannot be
structured – new tasks
on the fly
• few repetitive elements
• very high degrees of
freedom for people
can be modelled cannot be
modelled

Issues
■ Can we strictly separate case from process?
■ Can we decide in advance which model type
is appropriate?
■ Is there no process flow in ACM?

Comparing Elements of BPMN and CMMN
BPMN CMMN
Task types: User, Manual Script, … Task types: Human
Subprocesses Process/Case Tasks
Events: start – intermediate – end
catching – throwing
event listeners (catching)
implicit events, milestones
Gateways/Events Sentries
Sequence Flow Sentry with empty condition
-- Discretionary Tasks
-- Stages
Lanes Roles

A combination of
control flow elements of BPMN
and discretionary tasks
and planning elements of CMMN
a suitable language
to deal with any kind of process.

BPCMN: A combined Process and Case Modeling
Language
Silver (2010): BPMN covers about
90% of what is needed for
business processes.
Start with BPMN and add the
necessary case aspects.

Proposal for a combined Process and Case
Modeling Language
■ Activities can be
♦ integrated in sequence flow ( BPM)
♦ initiated by Sentry ( ACM)
■ Gateways for explicit control flow
■ Lanes for assignment of tasks to participants
■ Allow discretionary tasks

Extension: Modeling Business Logic
knowledge in processes:
• supports practice
• skills, experiences
• know how
 business logic
knowledge about processes:
• process flow
• roles
• resources
 process logic

Conclusion
Modeling knowledge processes includes
♦ Model Process Flow  BPM
♦ Model Cases  ACM
♦ Modeling business logic  Decisions
in an integrated environment
The modeling language was developed in adoxx.org
