The document discusses BPMI standards for business process management, including BPMN for modeling business processes. BPMN consists of a single diagram type called a Business Process Diagram (BPD) that can be used to visually model processes, activities, events, gateways, and pools/lanes. The core elements of BPMN allow users to easily develop simple process diagrams that show the flow of activities from start to finish.

3. BPMI The Business Process Management Initiative (BPMI – www.bpmi.org) has been established to promote and develop the use of Business Process Management (BPM) through the use of standards for process design, deployment, execution, maintenance, and optimization of processes. BPMI has developed, or is in the process of developing, three standards to facilitate BPM: Business Process Modeling Notation (BPMN), as a standard for modeling business processes, Business Process Modeling Language (BPML), as the standard business execution language, and Business Process Query Language (BPQL), a standard management interface for the deployment and execution of e-Business processes. All standards have been developed using a solid mathematical foundation, which enables a BPMN to map directly to BPML , and any other rival business execution languages that are introduced

4. BPMN The Business Process Modeling Notation (BPMN) is a standard for model ing business process flows and web services. It has 2 goals: to provide a notation that is readily understandable by all business users. business analysts that create the initial drafts of the processes technical developers responsible for implementing the technology that will perform th e se processes. to ensure that XML languages designed for the execution of business processes can be visually expressed with a common notation BPML (Business Process Modeling Language) BPEL4WS (Business Process Execution Language for Web Services) , created in a joint venture by BEA, IBM, Microsoft, and others

5. Business Process Diagram (BPD) BPMN consists of one diagram , called Business Process Diagram (BPD) BPD has been designed to : be easy to use and understand provide the ability to model complex business processes

6. Core Set of Notations The core set of modeling elements enable the easy development of simple BPDs that will look familiar to most Business Analysts (like a flowchart diagram) Events Activities Gateways (used for business decisions and branching of flows) Pools and swim lanes

7. Modeling Events An event will either : kick off a process flow happen during a process flow end a process flow. BPMN provides a distinct notation for each of these types of events

8. Modeling Events BPMN enables you to specify the trigger type of the event, and denote it with a representative icon Specifying a trigger type to an event puts certain constraints on the process flow that you are modeling, which are explained in the table. For example, a timer cannot end a process flow. You can only draw message flows from and to message events These types of modeling rules, which are actually kinds of business rules, should be enforced automatically by the modeling tool providing support for BPMN

9. Modeling Events

10. Modeling Events

11. Modeling Activities An activity is work performed within a business process 3 types of activity: process  sub-process  task A process in the flow can contain sub-processes, which can be graphically shown by another Business Process Diagram connected via a hyperlink to a process symbol. If a process is not decomposed by sub- processes, it is considered a task – the lowest-level process. A ‘+’ mark in the process symbol denotes that the process is decomposed; if it doesn’t have a ‘+’ mark, it is a task.

13. Modeling Connections A sequence flow is used to show the order that activities will be preformed in a process Associations are used to associate information and artifacts with flow objects

14. Modeling Gateways Gateways are modeling elements that are used to control the sequence flow in a process Decisions, merges, forks, and joins in the process flow are modeled with a gateway symbol

19. Modeling with Pools and (Swim) Lanes By taking processes and placing them in pools or lanes, you are specifying who does what , for events you specify where they occur, and for gateways you specify where decisions are made, or who makes them. Typically, a pool represents an organization, and a lane represents a department within that organization But also other things, such as: a function (something that the organization performs, like Marketing or Sales or Training) an application (or computer software program) a location (a physical location in the company) a class (a software module in an object-oriented computer software program) or an entity (representing a logical table in a database)

23. Άσκηση Χωριζόμαστε σε ομάδες ανά 2 Κάθε ομάδα προσπαθεί να σχεδιάσει την διαδικασία που περιγράφεται παρακάτω: Αρχικά παραλαμβάνεται μία παραγγελία. Στην συνέχεια γίνεται έλεγχος αν η παραγγελία είναι αποδεκτή ή όχι. Αν η παραγγελία απορριφθεί, κλείνει η πραγγελία. Αν γίνει αποδεκτή, συμπληρώνεται η φόρμα παραγγελίας, και ταυτόχρονα, γίνεται η αποστολή της παραγγελίας και η αποστολή του τιμολόγιου. Αφού αποσταλλεί το τιμολόγιο, κάποια στιγμή γίνεται η πληρωμή του ποσού και στην συνέχεια επιβεβαιώνεται αυτή η πληρωμή. Αφού ολοκληρωθούν τα βήματα αυτά κλείνει η παραγγελία. Κάποιος εθελοντής σχεδιάζει την διαδικασία που ετοίμασε στον πίνακα
