- External Business Events: EBE's, in combination with business rules, provide channels for messages in BPMN business process. For example, a purchase order has been issued through an X11 file, critical equipment has been recalled by the manufacturer, and sensor data has reached a limit.
- Internal Business Events: IBE's can arise, from the IT infrastructure and a business process is particularly adept at handling these.
IBE's and EBE's can be seen indirectly in the OMG's Business Motivation Model. The OMG's BMM is an essential link between business planning and modeling and business processes management. It utilizes a set of integrated concepts to define the elements of a business plan. These elements support a variety of approaches for creating and maintaining a business motivation model for the enterprise. As seen in the figure below, a business motivation model is parameterized in terms of means, ends, influencers, and assessments. It includes reference elements and business vocabulary. BMM is particularly strong where business change drives supporting processes.
IBE's and EBE's arise from the influencers portion of the model. Internal influencers can assessed to be strength or weaknesses and an internal event, such as reaching or missing a key performance indicator, can be one of these. External influences (which are counted as opportunities or threats) are analyzed as parts of the business plan. Obviously, the external events we mentioned above might be an influencer.
