Perception gaps in customer expectations: Managers versus service providers and customers

Two new gaps are added to the 5-gap model proposed by PZB. These new gaps reflect the differences in the understanding of customer expectations by manager and front-line service providers and in customer expectations and service providers' perception of such expectations. Using room service as the object for investigation, the present study provides empirical evidence indicating the existence of these gaps which have negative impact on overall service quality. The findings also disclose that the gap between customer expectations and managers' perception of such expectations is much larger than the gap between customer expectations and service providers' understanding of such expectations.
