Purpose Focal service providers increasingly involve customers in the decision-making about outsourcing parts of the service delivery process to third parties. The present study investigates how customers' outsourcing decisions affect the formation of the waiting experience with the focal service provider, by which the objective waiting time, environmental quality and interactional quality act as focal drivers. Design/methodology/approach To test our hypotheses in the context of cancer care, we gathered process data and experience data by means of a patient observation template (n = 640) and a patient survey (n = 487). The combined data (n = 377) were analyzed using Bayesian models. Findings This study shows that opting for a service triad (i.e. outsourcing non-core services to a third party) deduces customers' attention away from the objective waiting time with the focal service provider but not from the environmental and interactional quality offered by the focal service provider. When the type of service triad coordination is considered, we observe similar effects for a focal service provider-coordinated service triad while in a customer-coordinated service triad the interactional quality is the sole experience driver of waiting experiences that remains significant. Originality/value By investigating the implications of customer participation in the decision-making about outsourcing parts of the service delivery process to third parties, this research contributes to the service design, service triad and service operations literature. Specifically, this study shows that customer outsourcing decisions impact waiting experience formation with the focal service provider.Purpose Focal service providers increasingly involve customers in the decision-making about outsourcing parts of the service delivery process to third parties.
