The Object Management Group (OMG) is promoting the Model Driven Architecture (MDA) approach to support interaction among enterprises based on business process models. Based on this paper, the authors discuss in this paper how to specify performance indicators among the levels with different degree of abstraction suggested in MDA. These indicators will drive the monitoring activities to check the execution of business processes involving networked enterprises. Connecting the different levels they also decrease the cost of implementing metrics as the measurement of the entities at one level can be based on the lower level.
