Visual workflow process notation and layout

In a method of a technology for visual workflow process notation and layout, a workflow process graphical user interface is generated. A plurality of activity nodes is arranged along a workflow path, with each activity node representing a work activity. The activity nodes are arranged on the workflow path in representation of an order of performance of work activities within the process of performing work. A material flow path is arranged adjacent to the workflow path. The material flow path is representative of a flow of a material through the work activities associated with the plurality of activity nodes. A resource allocation node is disposed adjacent to a portion of the material flow path and one of said activity nodes. The resource allocation node represents a resource utilized in performing a work activity, represented by the adjacent activity node, upon a material represented by the portion of the material flow path.
