Abstract: | ABSTRACT The quality of relationships built with customers during the New Service Development (NSD) process is a current concern of researchers in relationship marketing (and NSD) and is particularly important in a highly competitive environment characterised by rapidly changing customer needs like the one of financial services. The primary relationship analyzed in relationship marketing is the one between seller and buyer, but the focal type of relationship for new product and service development is the one termed “the knowledge relationship” (Gummesson 2002), a relationship used to create knowledge. This paper reports the results of in depth qualitative research on the factors that impact on the quality of such relationships developed between new service developers and their customers during the NSD process of business-to-business financial services. Results show that the most important factors that affect relationship quality are: communication quality of the relationship; the development of strong relationship bonds; the quality of relationship partners; a strong customer orientation in NSD based on a proactive approach of relationship partners during the NSD process, and proficiency in knowledge brokering. |
