Processing steps are determined and optimized during the production of sheet metal forming parts, for example, by means of deep drawing/stretch forming processes. During the determination, by means of a computer-assisted design system, of process operations (PO 1 -PO 6 ) for the description of forming processes on a forming part, the following steps are carried out: defining geometry models for the computerised description of a geometry of the forming part in a target state; defining several geometry operators (m 1 -m 9 , e 1 -e 6 ), wherein one geometry operator (m 1 -m 9 , e 1 -e 6 ) associates a geometry of an area of a first geometry model with a geometry of an area of a second geometry model, and the geometry operator (m 1 -m 9 , e 1 -e 6 ) describes a transition from one of the two associated geometries to the other one; and defining several groups of respectively at least one geometry operator (m 1 -m 9 , e 1 -e 6 ), wherein each one of the groups is respectively associated with a process operation (PO 1 -PO 6 ).
