Exercise 9.2 Consider the following questions about a BPMS: Why would it not be sufficient to only propose business process model with the modeling tools, without any information on the types of resource that are available? In what situation will the execution engine generate multiple work items on the basis of the completion of a single work item? Can you provide examples of external services that may be useful to be invoked when a participant wishes to carry out a work item? What would be a minimal requirement to be able to pass on work items between the BPMSs of the insurance company that was provided as an example? If it is important that a BPMS hands out work items to available resources, can you imagine other, relevant types of information on resources that are useful to be captured by an administration tool (apart from whether they are ill or on vacation)?
