Abstract: | In this paper an argument for validation of design decision
methods is presented. In the process of justifying the need for
validation, the elements of what a valid design methodology is
are derived and a formal definition is presented. Under this
definition, critical evaluation of two popular decision support
methods, the House of Quality and Suh’s Axiomatic Design, is
presented using a simple design problem and both are shown to
be flawed under the proposed definition of validity. This does
not imply that the methods are ineffective. In fact, under the
appropriate assumptions, they are quite useful. However, in
this paper, an investigation of the validity of these assumptions
is conducted, including a more general definition of validity
with respect to decision support methods in design |
