One critical step in new product development is selecting from among multip
le possible product concepts the one that the firm will carry forward into
the marketplace. There is a need for low-cost, parallel testing of the appe
al of new product concepts, the results of which closely mirror ultimate ma
rket performance.
In this article, the authors first describe an Internet-based product conce
pt testing method they developed that incorporates virtual prototypes of ne
w product concepts, substituting them for physical prototypes. The method c
an be used with either static representations of the products or with dynam
ic representations that demonstrate how the product works through a simulat
ed video clip of its operation. The objective of this method is to allow de
sign teams to select the best of several new concepts within a product cate
gory with which to proceed without having to develop physical prototypes.
The authors then provide a rigorous test of both virtual prototype methods
against tests using both physical prototypes and attribute-only (i.e., no v
isuals), full-profile conjoint analysis. Nine concepts compete against two
actual products in rite rests. Market shares from the test using the physic
al prototypes are defined as the "actual" market shares. Predicted market s
hares for the attribute-only, full-profile conjoint analysis and each of th
e two virtual prototype methods are compared to those obtained for the phys
ical prototypes.
Both static and animated virtual prototype rests produced market shares tha
t closely mirrored those obtained with the physical products, outperforming
the set of predictions across the full range of products produced in the a
ttribute-only conjoint analysis, Interestingly, the attribute-only conjoint
analysis identified the top three products, in correct order. It was unabl
e to differentiate performance below these top three products. Furthermore,
it predicted market shares for the top three products to be well below tho
se achieved using physical prototypes.
As virtual prototypes cost considerably less to build and test than their p
hysical counterparts, design teams using Internet-based product concept res
earch may be able to afford to explore a much larger number of concepts. Vi
rtual prototypes and the testing methods associated with them may help redu
ce the uncertainty and cost of new product introductions by allowing more i
deas to be concept tested in parallel with target consumers. (C) 2000 Elsev
