ABSTRACT
In his award winning ‘business book of the year’1 Clayton Christensen (1997) investigated why well run companies that were admired by many failed to stay on top of their industry. His research showed that in the cases of well managed firms such as Digital, IBM, Apple and Xerox, ‘good management’ was the most powerful reason why they failed to remain market leaders (sic). It was precisely because these firms listened to their customers and provided more and better products of the sort they wanted that they lost their position of leadership. He argues that there are times when it is right not to listen to customers. Recent research by Ovans (1998) supports this claim. He suggests that purchase-intention surveys are not effective predicators of sales of new products. The research revealed that people aren’t generally reliable predictors of their own long-term purchasing behaviour. The type of question used and whether or not the question is placed in context greatly affects the reliability of such market research. James Dyson has good reason to be suspicious of the role of market research in new product development. Not only did he struggle for many years to get anyone in the UK to believe it was worth manufacturing his bagless vacuum cleaner, he faced the same scepticism when he launched in the US (Thrift, 1997).
