Purpose The purpose of this paper is to assess, clarify and consolidate the terminology around the co-creation of services, establish its forms and identify its outcomes, to resolve the conceptual pluralism in service co-creation literature. Design/methodology/approach A focused literature review screened the articles published in five major service research journals to determine relevant contributions on the concept of co-creation of services. Then, a thematic analysis identifies the forms, themes and outcomes of co-creating services in the set of 80 qualifying articles. Findings The study reduces conceptual pluralism by establishing different forms of co-creating services and developing an explicit definition of co-creation in services. The authors develop an integrative framework that recognizes involvement, engagement and participation as prerequisites for co-creation. Relating to the different phases of the service process, the specific co-creation forms of co-ideation, co-valuation, co-design, co-testing and co-launching are classified as regenerative co-creation, while the specific co-creation forms of co-production and co-consumption are recognized as operative co-creation. Both beneficial and counterproductive outcomes of co-creation are identified and arranged into a typology. Research limitations/implications The integrative framework illustrates that service providers and customers are involved, engaged and participate in co-creating services, which manifests in specific forms of co-creation; they attain beneficial and counterproductive outcomes (personal, social, hedonic, cognitive, economic and pragmatic); and are influenced by a contextual multi-actor network. Practical implications Co-creation in services is actionable; the typology of outcomes suggests service managers ways to motivate customers and employees to participate in co-creating services. Originality/value This paper defines and establishes the conceptual forms of co-creating services and the identified outcomes, and develops an integrative framework of co-creation in services.

Purpose This paper investigates factors that determine users’ behaviours during services co-creation, as well as those that influence their engagement in such efforts. Design/methodology/approach Study 1 relies on partial least squares structural equation modelling and between-subjects, scenario-based experiments with 633 participants to examine users’ co-creation behaviours. Study 2 uses interactive research workshops with 38 design professionals to analyse the drivers and inhibitors of users’ co-creation engagement and the likelihood of different user types to engage in it. Findings Dispositional and demographic factors can predict users’ behaviours during services co-creation. A proposed framework details drivers and inhibitors of users’ engagement in co-creation, and a typology predicts the likelihood of different users to engage in co-creation, based on their traits and demographics. This likelihood to co-create, according to traits, then can be predicted according to elemental, compound and situational traits. Practical implications Service providers and service designers can use these findings to design better co-creation activities for various users, build a conducive working environment and select suitable participants for co-creation activities. Originality/value The current study addresses the dearth of research pertaining to how to encourage users to co-create services and drive their engagement in such efforts.

Purpose Despite ample research on the adoption of online banking, the post-adoption phase remains largely neglected. The purpose of this paper is to develop a new conceptual model to investigate drivers, attitudes and behaviours in the post-adoption phase of the e-postbox, a co-creative online banking feature. Design/methodology/approach Research from bank marketing, services marketing, information systems and relationship management informs the proposed post-adoption model. Empirical tests rely on structural equation modelling and a sample of 750 current customers of the e-postbox of a large German bank. Findings The proposed model provides a multifaceted view of the post-adoption phase, including task-related, organisation-related and interpersonal communication-related drivers. This study reveals the importance of integrating dual interpersonal communication as a post-adoption driver and a post-adoption behaviour. It also extends the technology acceptance model by applying it to the post-adoption phase. Significant effects of age further suggest that younger customers express the most favourable attitudes towards and highest intentions to continue using the e-postbox; interestingly, older customers use it more and share more word-of-mouth. Research limitations/implications This paper develops a post-adoption model that highlights the importance of continued usage for successful co-creation between the bank and its customers. Practical implications Managers can encourage continued usage during the post-adoption phase of a co-creative, digitalised service, which determines the retention of current customers and opportunities to attain new customers. Originality/value This study defines and establishes constructs for the post-adoption phase and categorises them according to post-adoption drivers, attitudes and behaviours.
