First Activiti presentation given at B2B by practice summit on June 17th 2010

1. Consolidating the BPM market

2. Agenda What is Business Process Management? What is Activiti? What can Activiti do for you? As a business person As a developer As system admin

3. What is BPM? Management discipline Software engineering

4. BPM As A Management Discipline Make your company more efficient Analysing Documenting Optimising Business processes

5. What do you need for BPMAAMD? Many tools Napkin, Whiteboard, Word, Excel,… Many model types Process modeling Good BPMN drawing Descriptions Notes Versioning Collaboration

6. BPM As Software Engineering Draw execution flow in a tool Decorate diagram with technical details Run process on BPMS BPMS Keeps track of state Acts as central coordinator Executes automatic pieces Essentially a state machine

7. What do you need for BPMASE? Runtime engine Executable processes as input Coordinates executions Keeps track of state

8. Getting it wrong Typical product We can start from a business level diagram And then execute it on a system So many hidden options Notation vs execution language General purpose  complex language Specific  simple language Context Web services / SOA / ESB Java ECM Human tasks Result Graphical programming for business analysts A lot of niche products Fragmentation

9. Activiti’s pragmatical approach Business people don’t write software Executable processes Combines diagram and tech details It’s software Under control of developers Inside software project Facilitate collaboration Diagram provides common language Level of business people

10. An example var a = 1; a = a + 1; println(a);

11. Deploy the executable process var a = 1; a = a + 1; println(a); BPMS Runtime Engine

12. Start a new process instance BPMS Runtime Engine var a = 1; startProcessInstance a = a + 1; println(a);

13. BPMS as the central coordinator

14. A human task activity Create entry in task list Wait Store state in DB When task completes Send event to process instance Process instance continues var a = 1; approve println(a);

15. A human task activity BPMS Runtime Engine Tasklist Manager var a = 1; startProcessInstance John Doe | Approve Process Instance approve event println(a);

16. State machines and transactions BPMS acts as coordinator External actor means wait state for BPMS Examples Human tasks Webservice principle: “I’ll call you back” Wait for arrival of some asynchronous message Approve

17. State machines and transactions Upon arrival of execution in wait state Store current execution state Position Context variables Commit transaction While waiting No blocked threads / resources Upon resume Load execution from DB Continue executing

18. Timers Create a timer when activity is entered Cancel timer when activity is left Fire timer when duedate arrives approve escalate

19. Asynchronous Continuations Job Executor pdf-g Transaction 1 Transaction 2

20. Transactional Control Flow Specify overal execution flow Analyse where the external triggers are Activiti wil juggle with Execution state Timers Messages And call your POJO beans where needed

21. BPMS DB contents Process definitions repository Versioned Process instances Runtime state History Statistics

22. A Process

23. An Execution Execution

24. History HISTORY_PROCESS_INSTANCE ID START END … PROCESS 10:04 1 09:38 Order-1 09:39 1 09:38 1 Calculate Quote 2 09:39 1 Check Credit 09:42 3 09:42 1 Accept Quote 10:03 4 10:03 1 Charge Customer 10:04 HISTORY_ACTIVITY_INSTANCE ID START END … HPI ACTIVITY
