Abstract: The invention relates to apparatuses, methods and programs for identification and presentation of suggested process flow structures on a display device, as selectable options for addition to a partially generated process flow structure. The system of the invention comprises a graphical environment controller, a comparison engine, and optionally any one or more of a display controller, a structure-record convertor, a record-structure convertor, a repository, and a display device. The invention receives a first user input identifying a node within a first process flow structure. A second process flow structure is retrieved from among previously stored process flow structures, based on identifying a predefined degree of similarity between the first process flow structure and the second process flow structure.
