2. When to Model Cases vs Processes
Cases
• Managing a context to achieve
a desired outcome
Processes
• Taking steps to achieve
a desired outcome
Deciding is an activity present in both Processes and Cases

3. When to use BPMN, CMMN or DMN
is a about Processing
DMN
is a about Decidingis a about Managing

4. Variable
Every work effort instance
looks slightly different
Unpredictable The exact course of action is
unknown and highly
situation specific
Emergent
The exact course of action
only emerges during process
execution when more
information becomes
available
DMN
When to use BPMN, CMMN or DMN

5. Processes Cases Decisions
Activities Events Rules
Transitional Contextual Applied
Data Information Knowledge
Procedural Declarative Functional
Token
Event Condition Action

First Order Logic

6. Multiple Notations vs Unique Notation
• Separation of concerns
• Each notation captures the diversity of each points of views
• Expressiveness vs simplicity
• A unique notation would potentially lead to notational overload
• Alignment versus integration
• Elements from certain view(s) cannot be captured in other view(s)
• These views do need to align into a coherent whole
• Enabling a best of breed market
• Tool vendors can specialize
