BPM ACM?

Classification of Processes

partly translated from (Gadatsch 2005, S. 44)

structuredprocess

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 bemodelled

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 – endcatching – throwing

event listeners (catching)implicit events, milestones

Gateways/Events Sentries

Sequence Flow Sentry with empty condition

-- Discretionary Tasks

-- Stages

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
