ABSTRACT
However, manufacturers that cannot accurately identify these consumer values and subjective impressions and incorporate the corresponding elements in their
vehicle designs will find it difficult to remain competitive in the market. The author has therefore concluded that traditional design processes, which are implicit and rely heavily on designer intuition and experience-based rules of thumb, must be reformed employing an advanced Total Development System (TDS) through New Just in Time (New JIT) (Amasaka, 2002, 2007b,c; Amasaka et al., 2008).
