BPMN and Business Process Management Executive Summary BPMN stands for Business Process Modeling Notation. It is the new standard for modeling business processes and web service processes, as put forth by the Business Process Management Initiative (BPMI – www.BPMI.org ). BPMN is a core enabler of a new initiative in the Enterprise Architecture world called Business Process Management (BPM). Business Process Management is concerned with managing change to improve business processes. BPMN consists of one diagram – called the Business Process Diagram (BPD). The BPMN Business Process Diagram has been designed to be easy to use and understand, but also provides the ability to model complex business processes. It has also been designed specifically with web services in mind. BPMN is only one of three specifications that the BPMI has developed – the other two are a Business Process Modeling Language (BPML) and a Business Process Query Language (BPQL). All have been developed using a solid mathematical foundation, which enables a BPMN Business Process Diagram to map directly to BPML, in the same way that a physical data model maps directly to Data Definition Language (DDL). There are competing standards to BPML, chief among them is the Business Process Execution Language For Web Services (BPEL4WS) created in a joint venture by BEA, IBM, Microsoft, and others. However, BPMI has created BPMN so that it maps readily to any business process execution language.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
