The impact of waiting on customer‐instigated service time: Field evidence from a live‐chat contact center
研究了在线聊天服务中，等待时间如何影响客户自身贡献的服务时间，发现等待在服务初期加速客户参与，但随后产生减速效应，而服务中的等待则持续减慢客户响应。
Abstract It is well known that the waiting time a customer experiences in a service system is determined by the service processing time of preceding customers, among other factors. We argue that a directionally opposite effect, which diffuses from waiting time to her own service time, also exists in co‐productive service contexts where a significant fraction of the service time is contributed by the customer. Multiple underlying customer behavioral mechanisms lead us to hypothesize that waiting's impact is dependent on the service stage and magnifies as the service process approaches completion. Our empirical analysis uses a unique operational data set that combines server log information with instant‐messaging transcripts collected from a live‐chat contact center. We show that pre‐service waiting accelerates customer engagement—one dimension of customer instigated service time—only at the beginning of the conversation and then exhibits a slowdown effect as the conversation proceeds. In contrast, in‐service waiting consistently slows down customer responses—another dimension of customer instigated service time, the magnitude of which is higher in later episodes of the agent‐customer message exchanges. We discuss the practical implications of our findings on operational policies employed in contact centers.
