Suppliers versus Lead Users: Examining Their Relative Impact on Product Variety

Abstract

Collaboration with parties external to the new product development (NPD) process is seen as a means to reduce costs and improve the product offering to customers. On the suppliers' side, collaboration during the NPD process may lead to a faster and more efficient process. On the users' or customers' side, collaboration may provide ideas for entirely new products and/or modifications to existing ones. This paper examines how collaboration with suppliers and a group of users that experience needs unknown to the public, the so‐called lead users, affects the resulting variety of the products offered. The paper focuses on product variety because of its increasing perceived importance in the satisfaction of changing customer needs. Hierarchical regression analysis of survey data collected from 313 U.K. manufacturers revealed a significant positive relationship between collaboration and product variety. The key findings are that increasing the extent of collaboration with lead users and with suppliers during the NPD process will increase the variety of products offered to customers, and that lead users have a higher impact on product variety to suppliers. Previous studies have found that collaboration increases NPD performance, but to the best of the authors' knowledge, this is the first to explicitly explore the link with product variety. The paper concludes by discussing the findings' practical implications, limitations, and recommendations for future studies.
