In today's “experience economy,” service providers increasingly emphasize creating memorable, delightful service experiences. In this paper, we study the optimal sequencing and selection of activities in a service package to maximize user utility. Empirical literature shows an ideal schedule often entails an interior peak; that is, the peak (i.e., highest-utility) activity is scheduled neither at the beginning nor at the end of the package. Theoretic literature, in contrast, contends the peak activity should be scheduled either at the beginning or at the end. Our paper bridges this gap by developing a theory of interior peaks. It also provides managerial implications for activity sequencing and selection. We model the activity sequencing and selection problem as a nonlinear optimization problem, and reformulate its objective as an additive function to generate structural insights. We show heterogeneity in memory decay explains the phenomenon of interior peaks. The optimal sequence is in either an "IU" or "UI" shape. An interior peak is optimal when the memory-decay rate of the peak activity is neither too high nor too low. We show it can be optimal to schedule a low point immediately before the peak activity, creating a contrast in customer experience. In addition, as the peak activity becomes more memorable, one might be tempted to move the peak activity to an earlier slot; we show, by contrast, it can be optimal to move the peak activity to a later slot.
