In [1] different process modeling methods were evaluated and a tri-process modeling tool was developed. After that it is often the case that the recorded product development processes have to be optimized in this tool. Previous studies of the authors have described the stages of process optimization in detail . One of these stages was realized in [4] with the BAPM method. It has shown that there is no suitable method for the realization of the stage of process optimization called Simultaneous Engineering in the research literature. The aim of this paper is to show one approach to realize Simultaneous Engineering by quantifying the degree of parallelization of documents. With the improved triangle it is possible to represent the relation between parallelization, resources and risk. This paper allows a quantified estimation of the change in the risk to be provided during the parallelization of the elements of a process. Companies applying the optimization approaches discussed above will be able to perform more efficiently and create more efficient product development projects.
