In a recent Post, Geoffrey Moore expands his Systems of Engagement (SOE) vision to focus on disruption. Many by now are familiar with his views on SOE and next generation edge architecture. Mr. Moore describes a future dominated by Social and Mobile on the client side and Analytics and Cloud on the server side. In this recent piece, the focus broadens to include the inevitable disruption facing every industry. In doing so, he introduces a new Systems of Business (SOB) concept and provides some examples that highlight the differences between SOB and SOE. These examples help visualize a distinction that Mr. Moore is making between these two systems: systems of engagement instantiate new operating models, while systems of business instantiate new disruptive business models.
