Previous studies on the role of cost information in New Product Developme nt (N P D) prod u ci ng conflicting results. Motivated by those conflicting results whether cost information is beneficial or detrimental in the design process of new product, an experiment approach is adopted to examine the interactive effect of cost information types and strategy on the effectiveness of new product development. The results of this study show that cost effectiveness of new product design is enhanced when designers are facilitated with specific cost information rather than relative cost info rmation, with g re ate r mag n itude in low cost strategy orientation. Additionally, we find a trade off in low cost strategy orientation, namely as deslgners are provided with more precise cost information, their focus on product feature decreases.
