Definition
BPMN (Business Process Model and Notation) is an ISO standard (ISO 19510) for the graphical representation of business processes. BPMN uses a set of standardised symbols - tasks, gateways (decision points), events, and sequence flows - to model processes in a way that is readable by both the business side and the IT side. BPMN was originally developed by BPMI in 2004 and is now maintained by OMG (Object Management Group); version 2.0 from 2011 is the current standard. BPMN is best suited for structured, predictable processes with a clearly defined flow - for example, the supplier-switch process in ElhubNational hub for metering data and market processes in the Norwegian electricity market. (E01 → confirmation → E02 → activation date) or the billing cycle in CIS. Tools such as Camunda, Signavio, and Bizagi use BPMN as the basis for both modelling and process execution (BPMS - Business Process Management Suite). For the energy sector, BPMN is valuable for documenting and optimising processes across systems such as CIS, MDMMeter Data Management - system for collection, storage, quality assurance and distribution of metering data from the electricity grid., ERPEnterprise Resource Planning - business system integrating finance, HR, logistics and operations., and Elhub - particularly in improvement and migrationProcess of moving data, systems or services from one platform or environment to another. projects.
