Hi there,
I am relatively new to the world of BPMN. I am currently working on modeling our internal injection molding process. There are various sub-processes here and I’m finding it relatively difficult to decide how to model the systems in these sub-processes. For example: the operator measures a part and enters the data into a QM system. The system carries out an automatic check for completeness. If data is missing, it automatically sends an e-mail to the key user, who then has to enter the data manually. Is the QM system then a separate pool, a lane within the molded part inspection process pool, or are the tasks modeled as a service task within the operator lane?
Another example would be that the injection molding machine sends signals to a PLC. Based on the values, it issues a command to a robot. Should the systems be modeled as individual pools with message flows or as successive service tasks?
I would be very thankful for any kind of help.
