Interpersonal interaction in business triads—Case studies in corporate travel purchasing
Introduction
Service purchasing is an ongoing process involving individuals at different organizational levels in buyer and supplier firms (Crosby et al., 1990; Feisel et al., 2011; Grönroos, 2007; Wang and Davis, 2008). Purchasing services is generally viewed as more challenging than purchasing goods. There is increasing interest among academic researchers in service purchasing (Baltacioglu et al., 2007; Tate et al., 2010), but comparatively little research has so far been conducted on inter-organizational socialization processes that create relational value in buyer–supplier relationships (Cousins et al., 2006).
Although three actors are often involved in service purchasing, since service provision is increasingly outsourced to professional service providers, business relationships are generally studied from a dyadic perspective. It was therefore decided to apply a triadic perspective in this study to business relationships between an industrial buyer, its service supplier and intermediary partners. The purpose of the study was to investigate interpersonal interaction in business triads in service purchasing processes. The focus is on the interactions between individuals at two levels: strategic and operational. The specific question addressed is: How does social capital develop in business triads in the service purchasing and supply context?
The empirical setting of the study is corporate travel purchasing. Corporate travel is a business consumption service focusing on individual employees (cf. Wynstra et al., 2006). The supply side consists of a large network of suppliers, and a business trip with multiple destinations usually involves several suppliers. Corporate travel buyers traditionally outsource service delivery to a business travel agency to simplify the network, and to guarantee suitable routes and rates for each trip. Corporate travel is generally the second or the third largest controllable cost for a company (Upton, 2005), which makes it worth monitoring. The amount of money spent on corporate travel-related services is increasing, while the resources allocated to managing the purchasing are not increasing proportionally (cf. Ellram et al., 2004, Ellram et al., 2007). Corporations aim to decrease travel costs by reducing the cost per trip, not necessarily by diminishing the number of trips (Aquilera, 2008), thus putting pressure on efficient supply management. However, academic literature has paid little attention to effective management of corporate travel (Gustafson, 2011; Zhang et al., 2009).
In business research, there has been comparatively little application of social capital theory (Krause et al., 2007; Lawson et al., 2008). In this study, the structural, relational and cognitive dimension of social capital, as defined by Nahapiet and Ghoshal (1998), are applied in order to understand interpersonal interactions in the core relationships. The study contributes to the service purchasing and supply literature by analysing complex supply networks at the micro-level, and by providing concepts and models for the study of interactions in triadic contexts. The longitudinal approach adds to our understanding of ongoing service purchasing processes. Managerial implications focus on the importance of interpersonal interaction and trust creation between the firms and between the levels.
The study is organized in the following way. Section 2 sets the theoretical framework by discussing interpersonal interaction and social capital in the organizational context, the specific features of interactions in triads and in corporate travel purchasing. The Section 3 explains the research method and analysis procedures. Section 4 provides a description of the case firms and the informants, and the corporate travel purchasing function. Section 5 discusses the findings of the study. Finally, Section 6 concludes the study, and discusses its contributions and avenues for further research.

Interpersonal interaction and social capital in business relationships
Relationships can be seen as processes including product, service, information, social and financial exchanges that develop over short-time episodes. These episodes lead, with time, to institutionalization, adaptation, and long-term relationships (Håkansson, 1982). Business relationships are mainly established to manage financial transactions. However, organizations are also social entities, and business relationships develop in interactions among the individuals and groups of employees at
Research method and analysis procedures
The current study is a case study of interpersonal interaction in the context of service purchasing and supply. The exploratory nature of the research speaks for the case study method. The study is based on abductive research, and characterized by systematic combining, where the theoretical and empirical fieldwork and case analysis advance simultaneously (Dubois and Gadde, 2002). In systematic combining, the context and boundaries of the phenomenon are constructed progressively, as theory
Interpersonal interaction in corporate travel purchase—case study findings
This section is divided into three parts. The first presents the case firms and the informants. Thereafter follows a brief description of the development of the industrial enterprise's corporate travel purchase, and the actual analysis of the dimensions in interpersonal interaction.
Discussion
In the service purchasing context, studies including three actors became increasingly important, for reasons having to do with outsourcing. Outsourcing service purchasing involves always three actors. The roles of the actors, and the relationships between them change during the outsourcing process (see e.g. Li and Choi, 2009; van de Valk and van Iwaarden, 2011). Most business consumption services are contracted by the buying organization, and used by many individual employees. Thus, purchasing
Summary, conclusions and implications
Based on the purchasing and supply literature, and the industrial network approach, this case study investigates interpersonal interactions between an industrial enterprise, its travel agency and service supplier partners. Cooperation involves two main levels: the operational level with travel arrangements and supplier management, and the strategic level where the purchasing strategy and process development are defined. The longitudinal case study covers the industrial enterprise's

2020, Journal of Purchasing and Supply ManagementCitation Excerpt :The current study investigates co-development involving the participation of three actors because the procurement process inherently forms a triadic structure with a set of the following three linked actors (see Vedel et al., 2016): 1) the public unit managing the procurement process and acting as an intermediary between 2) service providers and 3) internal customers (Keränen, 2017a). In private-sector research, (service) triads have recently attracted interest (see reviews by Sengupta et al., 2018; Siltaloppi and Vargo, 2017; Vedel et al., 2016; Wynstra et al., 2015), but empirical case studies of purchasing and supply management investigating instances of three-actor collaboration are scarce (examples include, Dubois and Fredriksson, 2008; Hartmann and Herb, 2014; Holma, 2012; Uenk and Telgen, 2019; Wu et al., 2010). The concept of a service triad has been developed specifically for service outsourcing settings in which the buyer contracts with a supplier who delivers services directly to the buyer's customer (Wynstra et al., 2015), which is a typical situation in public service provision.

2019, Journal of Purchasing and Supply ManagementCitation Excerpt :Various other studies relating to this theme discuss the positive effect of trust between a buyer and a supplier in service triads on supplier performance (Finne et al., 2015; Gunawardane, 2012; Hedvall et al., 2016; Holma, 2010, 2012). In a longitudinal study Holma (2012) elaborates on the aspect of trust, demonstrating the importance of interpersonal interaction between firms. Having dedicated contact representatives who have the knowledge of processes and services is found to be valuable, because the bonds between these individuals provide channels for information exchange (Holma, 2012).
