Gateways control the direction and flow of a business process. An activity is either performed manually by a person or automatically through a system. Intermediate events (double thin lines) are events that happen in the middle of a business process, when it is already ongoing.Įnd events (one thick line) are events that occur at the end of a business process and every process must end with at least one type of end event.Īctivities are represented with a rectangle with rounded corners. Start events (one thin line on circle) are events that occur at the beginning of a business process and every process must start with an event Although BPMN describes business processes, it is not ideal for structured activities, which is why DMN and CMMN were developed to assist in model business cases.įlow Objects included in the design EventsĪn event triggers a start, modification and completion of an event. CMMN relies on a “case” that contains all the requirements for the process and gives workers access to the information they need to carry it out.ĭMN and CMMN do not serve as substitutes for BPMN but are instead supplements to it. Triple crown of process improvement: DMN and CMMN in relation to BPMNĭecision Model Notation (DMN) is used to describe pre-determined business rules and requirements that are not included in the business process modelling.Ĭase Management Model and Notation (CMMN) is a type of business process technology which serves a different purpose than the BPMN because it does not use control flow to describe a process. For example, business analysts draft the business processes, while technical developers oversee implementing the technology that will help eexecute the processes. The primary goal of the BPMN is to provide a system that is understandable by all users.
BPMN diagrams can be used by different stakeholders inside and outside an organisation, ranging from business executives and business analysts to technical staff and administrative staff.
