Service delivery typically requires multiple interactions between customers and the service system. The production of
services involves flows of inputs and outputs between customers and providers (e.g. information), through the
interaction with employees and technology interfaces (Sampson, 2000, Frohele and Roth, 2004). Service scholars
acknowledge customer interaction as a key determinant of service quality, and have extensively investigated how
customers assess the interactions with providers. Many service contexts involve intense customer-to-customer
interaction (CCI) which can also have strong impacts for service results (e.g. retail stores, transportation services...). Yet,
to the best of our knowledge, research about how to design service delivery processes for effectively supporting CCI
has been relatively scarce. Our work provides a contribution to the field of service management by considering CCI as
a pertinent issue for service strategy and for the design of service processes. We conduct an exploratory study in the
context of trade fairs services which include CCI as core element of the service delivery. Organizers of trade fairs need
to setup service delivery processes which maximize the benefits from CCI for its customers. The work contributes to
the knowledge concerning the design and management of CCI by providing a set of research propositions which set
an agenda for empirical research about i) the characterization of distinct types of CCI in the context of CCI-driven
services such as trade fairs; and ii) the variation of CCI behaviors throughout service delivery, as well as with the
nature of customers goals in trade fairs.
