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

Example: „Underwriting“

Example: „Underwriting“

Example: „Underwriting“

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

CMMN as alternative

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!)

Now the process gets easier and more stable

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

Defined by CMMN Standard – no workarounds necessary

CMMN calls BPMN

CMMN can be best explained via UI

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

Task Lifecycle

Lifecycle Mapped on UI

Live Hacking…

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.

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

Structured vs. Unstructured work

Unstructured Processes Nonroutine Work

Structured Processes Routine Work

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, ...

Existant…

Nonroutine Creative Work

Interessting topics to look at in future: Adaptive Case Management, Process Mining, …

But it is important to distinguish

1. You have „Knowledge

Workers“

2. You are missing

discipline!

Often a question of maturity

End-to-End Process
