BPMN 2.0 Information sources
● Elegant way to express process structure
● Visual models are easily understandable
○ Understandable by process participants
○ Bridge gap between process description and it's
executable implementation
● Easy to express nested structure (sub-
processes)
● Process models easily understandable by all
roles in development cycle
Why process modeling?
Roles in development cycle
● Business Analyst
○ Sum business strategy
○ Describe goals & objectives, KPIs
○ Describe processes
○ Design BPMN diagrams (Level 1)
● Process specialist
○ Design BPMN diagrams (Level 1,2,3)
○ Design monitoring models
● Process developer
○ Detail BPMN Level 3
○ Implement services and deploy processes
Roles in development cycle
Modeling notations
● BPMN 1.0 – 1.1
○ Analytical modeling, not tight with semantics,
not executable
○ XPDL semantics
● BPEL
○ Technical modeling, very detailed
○ service orchestration, executable
● BPMN 2.0
○ Analytical modeling (Level 1,2)
○ Defined semantic – executable (Level 3)
BPMN 2.0 Three levels
● Level 1 (Structure)
○ Capture basic structure of the process
○ Good for both business and technical people
● Level 2 (Analytical)
○ Add more details to Level 1 diagrams
○ Good for process analysts
● Level 3 (Executable)
○ Specify all used services and activity tasks
○ Allow execution
Process domains for
teamwork
● Artificial domains
○ Hospital
○ Bank
○ Insurance company
○ Airlines
○ Real estate agency
○ Court
○ Package delivery
○ Software company
○ IT support center
○ Car manufacturer
● Custom domain
○ ++ exam advantage
○ Your own work
experience
○ Proper opportunity
required !!
○ Backup plan needed

BPMN 2.0 (Level 1)
Object classes
● Flow Objects
○ Event
○ Activity
○ Gateway
● Connecting
Objects
○ Sequence Flow
○ Message Flow
○ Association
● Artifacts
○ Data Object
○ Group
○ Annotation
● Swimlanes
○ Pool
○ Lane
BPMN 2.0 – Process example
Flow object - Activity
● Represent certain step, an activity
● Types of activity
○ Atomic activity = Task
○ Complex activity = Subprocess
● Types of task
○ Service task
○ User task
○ Manual task
○ Script
Flow object - Event
● Represent event that occur in a process
● Have impact on process flow
● Types
○ Start
○ Intermediate
○ End
○ Extending elements
Flow objects - examples
Flow object - Gateway
● Stands for flow branching or join of
branches
● Types
○ Exclusive data-based (XOR)
○ Exclusive event-based
○ Inclusive
○ Paralel
○ Complex
● Default branch
Gateway examples
Gateway examples II
Connecting Objects
● Sequence flow
○ Define order of activities
●
● Message flow
○ Message flow between two objects
●
● Association
○ Connect objects with artifacts (labels,data objects..)
Artifacts
● Additional information
● Do not affect flow
● Data Objects
○ Data used in activities
○ Inputs and outputs of activities
● Annotation
○ Label, additional information
● Groups
○ Grouping of objects
(analytical/documentation reasons)
Artifacts - examples
Swimlanes – Pools/Lanes
● Pool
○ Represent a participant in a process
○ Show message flows between participants
● Lane
○ Subdivision of pool
○ Express roles, departments or actors in a
process
Pool/examples
Pool/examples
Private (Internal) Process
● From point of view of one organisation
● Activities are not visible to outside world
● One pool (if used)
Abstract (Public) Process
● Only activities that send/receive
messages
● Communication visible to outside world
Collaboration (Global)
Process
● Collaboration between more business
entities
● Activities represent message exchange
Assignment (Homework)
○ Create one BPMN process model (Level 2) from your
team’s domain
■ 8+ activities
■ 4+ gateways, 2 different types
■ 3+ events, 2 different types (beside start a end)
■ 1+ data object
■ 2+ text annotations
■ 2+ pools, 1 as „blackbox“, 2+ roles (swimlanes)
■ 1+ exception and handling
○ Submit printed version to the box called "PV207"
next to entrance to room D1, before 31.3. 20h
○ Submit electronic version
■ Export to PNG in Signavio, submit to IS MUNI to folder
"homeworks" before 31.3. 20h as <surename>_bpmn.png
Hands-on: Teamwork process
● PV207 process
○ First BPMN session
■ Students form teams
■ Team choose process field for their team
■ Students each of students create one process
model
○ Second BPMN session
■ Lecturer check process from last session
● IF the process is ok
● IF not, they rework it until next week
