Palladio Developer Wiki

Palladio and Business Processes

Research Topic: Business process of interest with an IT supported subprocess
predicting the it process and integrating these results in the overall process analysis
Model perspective: BPMN modelled processed
Performance and reliability are of interest. Also in the manual business process steps
Where does the usage model / profile for IT process is derived from? In general from the business process
Possible connection: University of dortmund: Requirements -> overall business process -> it process
- The information (e.g., how many users are hitting the systems) are available in the requirements
- Where does the information come from? => Domain Experts / customer ... who ever is specifying the requirements
- Addition: self adaptive models / systems might improve the requirements
Current approach in Heidelberg: monitoring the system and deriving what the current workload might be
- Of interest: How is the business process reliability is effected by the IT process reliability
- Addition: deadlocks in multi-system scenarios
Important assumption: Long running IT process and / or IT system is not responding
- Worst case (e.g., system is in overload) are of most interest
Business process might have a workaround path for non-responsing IT systems but performance might be influenced
- reliability issue in the it process might be a performance issue in the business process
using palladio in a forward-engineering approach (build models from scratch)
- how do you know if hardware is sufficient? also look at total cost of ownership (hardware is cheaper than development costs)
- the better approaches can be automated, the more likely industry will use approaches

Eclipse Indigo

A stable 3.7 build is working
An issue with the stoex parser was already existing with 3.5
How to handle with eclipse releases in general and also in a long term perspective
- Also in combination with other tools (QImpress, .....)
Rate during the organisation session how to deal with existing tools not part of an active research process -> problem funding
- OCL constraints do not work in 3.5

General Community Notes

Reflect the responsibility voting process
- Community has grown over the borders of karlsruhe -> so even the responsiblity should do
- Awareness of issue severity
Regular virtual meetings / Concall PCM Development/Palladio Concall
Wiki separation: Keep in mind that there are not just internal and external but also external palladio vs. external everything
