A top‐own scenario based approach is a typical method generating the product breakdown structure (PBS) in systems engineering. While it takes time and effort to perform the scenario based PBS construction, it is the safest approach not to omit any functions. On the other hand, a design structure matrix (DSM) approach to PBS construction is a bottom‐up approach based on modularization concept that provides a merit of quick PBS construction while the sanity of its results may not be assured. Accordingly, this study presents trade‐off results between the two approaches to uncover problems in the DSM‐based clustering method and proposes improvement approaches to enable the interfaces with external systems, static elements, as well as a new capability to handle the large number of clustering elements.
