Process implementation method based on business process modeling notation international standard

The embodiment of the invention provides a process implementation method based on a business process modeling notation international standard. The method comprises the following steps that: an information sending behavior of a current process calls a processing start behavior of another process, and the current process sends the relevant information of a project to another process; another process receives the relevant information of the project and processes the relevant information of the project; a result sending behavior in another process calls a result receiving behavior of the current process, and another process sends a processing result to the current process; and the current process receives the processing result. By adoption of the method provided by the embodiment of the invention, external sub-processes and sub-processes are eliminated, so the problems caused by the external sub-processes and a plurality of sub-processes are solved, and the development efficiency of the processes is improved.
