BPM/BAM/CEP/SOA/EDA-Workshop in Ireland (2)

February 15-22, 2008

We continue our imaginated session at the bank.
In the meantime, the colleagues of the operating and IT-departments are back from lunch. But we had to send them directly to the coffee bar, because our WID specialists were not successful so far with importing the business process of the WebSphere Modeller into the BPEL-platform of WID.

Our specialists stated that it wouldn’t be a good idea to insert roles and resources already in WebSphere Modeller. On the one hand, human tasks are documented and modelled according to the archived processes, but on the other hand some of the human tasks are no longer needed for a remodelled BPM-based process, if human tasks shall be replaced by automated process steps, e.g. “check legitimation”, “create depot” (which kind of depot can now be decided automatically by the implemented process) etc.

At the first trial of importing, we were surprised that only a “torso” of the process was imported into WID. For example the sub process, which we had extra isolated as a reusable legitimation process to work in other contexts, was not imported:-( Perhaps a principal fault? Or a cosmetical problem of the release of WID May 2007, V6.0.2? Or did we anything wrong? We’ll ask the hotline…

So, we found and trained some work arounds for the problems, e.g.:
- Remove all the human tasks respectively the roles and resources in WebSphere Modeller
- After those modifications we could import.
- We replaced the decision nodes we firstly created in WebSphere Modeller.
- “Multiple choice decisions” are not transferred into BPEL-choice. They were presented on the flow model as expressions and conditions. So there is some work to maintain the process.
- Then we had to delete an “Empty Task” which was generated automatically between a merge and a multiple choice during the import.
And some more...

Ooooops! After a long coffee break (actually a whole day) for the imaginated bank colleagues, we could continue the delayed afternoon session with the colleagues of the bank.

Summarized, here are our recommendations in order to make the process executable and to deploy it:
1) If there, prepare the documentation of the business process in WebSphere Modeller.
2) Define a team with a skilled moderator, an WID specialist and the relevant persons of the operating and the IT departments.
3) Find an appointment for a 1-day session with this team.
4) If no documentation of the process is available yet, you can risk to start the meeting with all the team members from scratch and model the process directly in WebSphere Modeller on the basis of the todo’s/not todo’s of our work arounds.
5) Import the process of WebSphere Modeller into WID for facilitating the discussion with the operating and IT departments in the morning session.
6) Import the model during the lunch break. Accept “suboptimal” BPEL code, e.g. for multiple choices/decision nodes.
7) Continue the discussion after lunch about inserting partnerlinks, WSDL`s, compensations, exceptions, roles, resources, peoplelinks etc. directly on the basis of WID/BPEL.
8) Make the process executable in the afternoon session and discuss, modify and release the prototype until the end of the afternoon session.
9) After that, fly home and optimize the BPEL code “remotely” at home for a better maintenance of the business process in the case of future changes.

To publish the process could be a little tricky. Sometimes you get an error, but after another try the publishing works correctly.

Our result: it should work to make the prototype of the process deployable in one afternoon session and to discuss and modify the process implementation on the fly in a very flexible way. Sounds great!!!

So, we can now continue with inserting and implementing the KPIs and with designing dashboards. We’ll do this job in another session with the appropriate employees directly at the customer.

Congratulations to our workshop from Bill Clinton as well:-) He also liked Mary Ann's restaurant
