Black et al. (1990) have applied parameter-based DSM method to
automobile brake system design. This work enabled designers to
investigate the best initial points for iterated design and helped the
company develop a systematic approach to low-level design process
planning. Cesiel (1993) documents a similar application where designed
experiments were used to study the parameter-based design options.
Dong (1999) has analyzed the design processes of various parts of a
car using parameter-based DSM. Rask and Sunnersjö (qtd. in
Browning, 2001) have used the method to describe the relationship
between design variables of a robot arm and its housing. Previously,
design parameters were separated into two, coupled “meta-activities”:
“design arm housing” and “design arm.” The DSM model was used to
sequence and integrate the low level activities in a new way. The
method has also been used at Boeing Company to plan the
development of a multivariable wing analysis tool. Listing subroutines of
the new tool, which were once individual analysis tools, as rows in the
DSM and noting their necessary data exchanges as interfaces, the
designer prescribed an efficient process for wing design procedures
(Browning, 1998). Mascoli (1999) has applied DSM as a tool to organize
design parameters at the conceptual design phase of aero-engine
