1. Introduction to BizAgi

2. Slide 2 User Interface (Summary) The user interface for BizAgi resembles Office It uses a similar ribbon The Palette contains the various symbols (Flow, Artifacts, Swimlanes, Connections) Draw these on the visual palette The Element properties section allows you to configure the selected element

3. Slide 3 User Interface (Illustration)

4. Slide 4 Creating a New Model Click File, New to create a new BizAgi model The design surface shows a process with a single pool Use the Basic properties to give the process a name Drag the Lane icon to the design surface to create a swim lane Use the element properties to name each swim lane

5. Slide 5 Creating the Model Use the Palette to drag symbols to the diagram

6. Slide 6 Events Fire as a result of something happening A message is received A period of time elapses An exceptional conditional arises We typically perform an action in response to an event

7. Slide 7 Events Fire as a result of something happening A message is received A period of time elapses An exceptional conditional arises We typically perform an action in response to an event

8. Slide 8 Event Types Message – Arrives from a participant Timer – Process starts at a period in time Rule (conditional)– Triggers when a rule becomes true

9. Slide 9 Event Types (2) Link – Connect the end event of one process to the start of another process Multiple – Multiple ways of triggering the process Exception – An error End events

10. Slide 10 Message Events Messages are typically sent by one participant and received by another Send sales order information that is received by accounting to check credit The event can be thrown or caught Sending a message means throwing a message Receiving a message means catching a message See MessageThrowCatch in EventSamples

11. Slide 11 Message Throw Catch Example

12. Slide 12 Timer Events The event fires a specific time or cycle Only applicable to start or intermediate events In BizAgi, use the Element properties to set the timer to a date or cycle Examples Time delay to approve credit Wait for payment date Start payroll process every two weeks See Timer in EventSamples

13. Slide 13 Conditional Events Events that fire when an external condition becomes true or false Process A/P checks on Mondays We could also implement this as a timer Inventory below threshold – generate order request Only applicable to start or intermediate events See Conditional in EventSamples

14. Slide 14 To Create an Event First, drag the event icon to the designer surface Right-click on the event and set the event type

15. Slide 15 Gateways 1 Gateways are used to depict decisions or merges Types Exclusive (XOR) Only one output (alternative) flow is allowed Gateways diverge or converge Inclusive (OR) A default output flow must be specified Parallel for / join (AND)

16. Slide 16 Gateways (2) Event-based gateways These are (Exclusive) gateways that rely on external messages

17. Slide 17 Gateway – XOR Example Exclusive XOR Decision See ExclusiveGateway in EventSamples

18. Slide 18 Gateway - OR Inclusive OR decision

19. Slide 19 Gateway – Example 3 Parallel Forking – All sequence flows drawn out of the gateway are taken

20. Slide 20 Processes and Tasks A process is a network of steps A process can be marked as having a sub- process To mark an activity has having a sub process, right-click the activity and click Transform to subprocess

21. Slide 21 Sub Processes – Illustration (1)

22. Slide 22 Data Objects First, we are not talking about a database or physical data We are talking about information about a process Data objects are attached to a sequence or message flow with a dashed line

23. Slide 23 Data Objects (Illustration)

24. Slide 24 Text Annotation Contains descriptive text about a process A line connects the annotation to the activity

25. Slide 25 Workflow Patterns (Introduction) In this second section of the lecture, we talk about simple and complex workflow patterns Much of this is derived from the AIFB paper (Modeling Workflow Patterns) in this lecture

26. Slide 26 Sequence Pattern Tasks are executed in sequence (one after another)

27. Slide 27 Parallel Split This is a logical AND gateway The parallel branches are executed concurrently

28. Slide 28 Parallel Split (Example)

29. Slide 29 Synchronization Two or more different branches get merged into a single branch All merged branches must be completed before the process can continue (Implied) Synchronization can occur because of a parallel split

30. Slide 30 Synchronization (Illustration)

31. Slide 31 Exclusive Choice Here, we are making a decision with mutually exclusive outcomes (Only one outcome is possible)

32. Slide 32 Exclusive Choice (Example)

33. Slide 33 Simple Merge A point in a process where two or more branches are merged into a single branch The initial branches are created via some type of choice

34. Slide 34 Simple Merge (Example)
