This is about how to create case management solutions with Camunda BPM. You will get a crash course in CMMN and understand the typical architecture of the accoding applicatins. Combining BPMN and CMMN will also be covered.

3.  Published by OMG in May 2014 as the BPMN-equivalent for „Cases“
 „Activities that are not so predefined and repeatable, but instead
depend on evolving circumstances and ad hoc decisions by knowledge
workers regarding a particular situation”
 Typical Use Cases:
−application and claim processing in insurance
−patient care and medical diagnosis in healthcare
−exception handling, e.g. problem resolution in call centers, invoice
discrepancy handling, data validation errors, …
 See http://www.omg.org/spec/CMMN/1.0/
 Camunda shipped CMMN 1.0 implementation with 7.2
CMMN

7. Example: „Underwriting“
There are workarounds – but
this is hard to model in BPMN.
You need more flexibility for
the „Knowledge Worker“
It is hard to give a stable
ordering of the tasks!
Flexibility needed.
100 % standardized –
no flexibility needed

8. CMMN as alternative

9. CMMN explained
Human Task –
automatically
activated
Process Task –
manually
activated
Milestone
Sentry – controls if
the Milestone is
reached
Sentry – controls if
the User Task is
enabled
Connector – to
visualize
dependencies
(no sequence flow!)

10. Now the process gets easier and more stable

11.  BPMN Standard does not (yet) support CallActivity for CMMN
 Camunda will introduce this with 7.3
 Workaround recommendation for now:
Alternatives:
 You can replace the Service Task by an Execution Listener if you
prefer
 You can hack the CallActivityBehavior
BPMN calls CMMN

12.  Defined by CMMN Standard – no workarounds necessary
CMMN calls BPMN

13. CMMN can be best explained via UI

14. Example UI for Case Instance
Task Form – to work
on Human Task and
see context from case
Case Context (could
show or link more
information)
Case Activities –
provided by engine,
correspond to lifecycle

15. Task Lifecycle

16. Lifecycle Mapped on UI

18. Live Hacking…

19. CMMN might be more complex (and powerful)
Sentry might take
data (variables)
into account.
A stage is one
„phase“ in the
case.
Exit Criterias can
mark results of a
case.

21. Current Toolchain
CMMN
Web Modeler
Developers DIE
(e.g. Eclipse)
Engine /
Application Server
Own application
with User Interface
Camunda Cockpit
with ACM Plugin
CMMN
File
+ PNG
Normal deployment
(e.g. WAR)
API
(Java or
REST)
API
(Java or
REST)

22. Cockpit Plugin
available via Plugin Store:
camunda.org/plugins
Special thanks
to our partner
Holisticon & Simon
Zambrovski

23.  Gain more real-life experience and collect feedback
 Work on CMMN coverage (Required, discretionary, events, …)
 Add Cases to cockpit
 Add CMMN-Modeler (on bpmn.io basis)
Next steps and further ideas

24. Structured vs. Unstructured work
Unstructured Processes
Nonroutine Work
Structured Processes
Routine Work

25. Typical patterns
Preparation Processing
Evaluation or
Decision
(by expert)
e.g. scanning,
validating, storing
master data, loading
additional data or
querying services, …
e.g. creating
policy/order/...,
provisioning, sending
letters, billing, ...
Automated Processing
Execption
Handling
e.g. manual processing,
correcting data and continue
automated processing, calling
customer to discuss, ...

26. Existant…
Nonroutine Creative Work
Interessting topics to look at in future:
Adaptive Case Management, Process Mining, …

27. But it is important to distinguish
1.
You have „Knowledge
Workers“
2.
You are missing
discipline!

28. Often a question of maturity
End-to-End Process

30. But:
Keeping flexibility might help you
on the first steps!

31. A real-life example (using plain BPMN)

32. Now you can add a switch!
