Because CE research originated in the engineering field, studies to date have mostly focused on technical and management-related topics. However, due to increasing demands from customers, investors, governmental institutions, and regulatory bodies, companies are increasingly considering how to effectively implement the CE. Despite its increasing importance, the CE is yet an uncharted area of transformative service research (TSR), and little is known about how the CE can support change for greater well-being among individuals and collectives. To fill this research gap, we integrate notions of the CE with TSR and research on value co-creation. The purpose of this paper is to expand research on CE and services by taking a TSR perspective to delineate how value retention and regeneration processes for different levels and spheres in services can effect change for greater individual and collective well-being.","PeriodicalId":506408,"journal":{"name":"Journal of Service Research","volume":"60 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139602369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is unclear whether collaborations between the human employee (HE) and DE can influence customer outcomes, and what the mechanisms behind such outcomes are. This research proposes and tests a theoretical model that explains how the communication of HE-DE collaboration in the form of interdependent behavioral cues can influence customer evaluations of the service they received from such a team. Five experimental studies involving a total of 1403 participants demonstrate that making HE-DE collaboration visible to customers during the service encounter can reinforce their perception of HE-DE team cohesiveness and service process fluency, driving satisfaction. The communication of coordination and team goal cues are two strong stimulants that strengthen such impressions. Further, this research also reveals that the HE-DE collaboration (vs. augmentation or substitution) appeals to customers thanks to their perception of a transparent process, which is induced through collaborative cues. This research provides theoretical implications for a transparent collaborative process between HE and DE and practical advice for firms seeking to integrate DE into their organizations’ workflows.","PeriodicalId":506408,"journal":{"name":"Journal of Service Research","volume":"115 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139605586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
