"OMG: Modeling the Business. The Real Revolution". Richard Soley presentation at the BPM Forum 2013 in Milan introducing a day of Business Process Modeling with some thoughts about this change and the impact on both technology and business. In the ITC world, most of the focus on modeling has been on technical artifacts: software, configuration, test development, and so forth. In business analysis, most of the focus of modeling has been based on ambiguous, natural languages. These worlds are colliding now, with semantically-rich, precise descriptions of business models useful as the basis for detailed, exact business analysis, communications and metrics.
