2 Sub Capaian Pembelajaran MK Mahasiswa mampu memahami konsep pemodelan proses yang penting maupun pemodelan proses lanjutan menggunakan BPMN

3 Sub Capaian Pembelajaran MK We are here!!

4 Example: no option to complete If condition_1 is true, the instance cannot complete and activity B will be repeated forever (livelock)

5 Find the bugs No Start Event F11 What?? Trivial Gateway F1 F2 F9 F12 Split or Join? F10 May deadlock F6 No End Event F3 F4 F7 F8 F5 Lack of synchronization Disconnected node

6 Information Artifacts and Resources in BPMN

7 Information Artifacts (Business Objects)

8 Our Order-to-cash process, again Send invoice Purchase order received Check stock availability Items in stock Items not in stock Reject order Confirm order Order rejected Ship goods Archive order The purchase order document serves as an input to the stock availability check. Based on the outcome of this check, the status of the document is updated, either to approved or rejected. If the order is approved, an invoice and a shipment notice are produced. Order fulfilled

9 Solution Purchase Order [checked] Purchase Order [approved] Send invoice Invoice Purchase Order [approved] Purchase order received Warehouse DB Check stock availability Items in stock Items not in stock Reject order Confirm order Order rejected Ship goods Shipment notice Archive order Orders DB Order fulfilled Purchase Order [rejected]

10 BPMN Information Artifacts Purchase order Emit invoice Invoice A Data Object captures an artifact required (input) or produced (output) by an activity. Can be physical or electronic Oracle CRM Retrieve client information Client info A Data Store is a place containing data objects that must be persisted beyond the duration of a process instance. It is used by an activity to store (as output) or retrieve (as input) data objects.

11 BPMN Text Annotations A Text Annotation is a mechanism to provide additional text information to the model reader Doesn t affect the flow of tokens through the process Includes packaging For blocked invoices Ship goods Clear vendor line items

12 Resources

13 Resources Active resources: Process participant Software system Equipment Resource class: A group of (active) resources that are interchangeable, e.g. a role, an organizational unit or the whole organization.

14 Resources in the order-to-cash example The order-to-cash process is carried out by a seller s organization which includes two departments: the Sales department and the Warehouse & Distribution department. The purchase order received by the Sales department has to be checked against the stock. This is done via an ERP module within the Warehouse & Distribution department. If the purchase order is confirmed, the Warehouse & Distribution department ships the goods. Meantime, the Sales department emits the invoice. The process concludes with the order being archived by the Sales department.

15 BPMN Elements Pools & Lanes Pool Captures a resource class. Generally used to model a business party (e.g. a whole company) Pool Lane Captures a resource sub-class within a resource class by partitioning a pool. Generally used to model departments (e.g. shipping, finance), internal roles (e.g. Manager, Associate), software systems (e.g. DBMS, CRM) or equipment (e.g. Manufacturing plant) Lane Pool Lane Lane Lane

16 Solution Order-to-cash

17 Pool 1 Pool 1 Pool 2 BPMN Elements Message Flow A Message Flow represents a flow of information between two process parties (Pools) Message A Message Flow can connect: directly to the boundary of a Pool captures an informative message to/from that party to a specific activity or event within that Pool captures a message that triggers a specific activity/event within that party Pool 2 Receive Send Receive Send

18 BPMN Elements Start Message Event The start message event triggers a process by the receipt of a message when an incoming message flow is connected to the event Message Message received

19 Order-to-cash

20 Pools, Lanes and Message Flows: syntax 1. The Sequence Flow cannot cross the boundaries of a Pool 2. Both Sequence Flow and Message Flow can cross the boundaries of Lanes 3. A Message Flow cannot connect two flow elements within the same pool

21 Process (or Orchestration) Diagram Models a single business party and can be: Public view (black box) Auctioning Service Auctioning Service Private view (white box) Conduct auction Send auction creation confirmation Auction begins Send auction creation confirmation Send auction completion notification

22 Bidder Auctioning Service Seller Collaboration Diagram Models a global business process between at least two business parties (each modelled by a Pool) Send delivery notification Auction creation request Send auction creation request Send auction creation confirmation Auction creation confirmation Auction begins Conduct auction Send auction creation confirmation Auction completion notification Send auction completion notification Send payment details Send payment ack.
