Benchmarking of service quality with data envelopment analysis

This paper proposes a data envelopment analysis (DEA) approach to measurement and benchmarking of service quality. Dealing with measurement of overall service quality of multiple units with SERVPERF as multiple-criteria decision-making (MCDM), the proposed approach utilizes DEA, in particular, the pure output model without inputs. The five dimensions of SERVPERF are considered as outputs of the DEA model. A case study of auto repair services is provided for the purpose of illustration. The current practice of benchmarking of service quality with SERVQUAL/SERVPERF is limited in that there is little guidance to whom to benchmark and to what degree service quality should be improved. This study contributes to the field of service quality benchmarking by overcoming the above limitations, taking advantage of DEA’s capability to handle MCDM problems and provide benchmarking guidelines.     

顾客感知服务质量评价方法的实证比较——对SERVPERF和SERVQUAL的再探讨

国内外众多学者对服务质量评价方法进行了深入的研究,产生了较多的评价方法,尤以SERVQUAL和SERVPERF应用最为广泛。但是关于两种方法的比较,学术界有不同的观点,实证研究认为：两种顾客感知服务质量评价方法的评价结果一致,且均具有准确的维度划分、较高的信度和效度以及变异解释能力,但是SERVPERF较SERVQUAL方法更易于回答且具有更高的信度、效度和变异解释能力。     

A comparison of Magal's service quality instrument with SERVPERF

The role of service quality has become critical to the success of organizations. Therefore, it is important to use a reliable instrument to measure information service quality. SERVQUAL is a popular instrument for doing this, but, though widely used, it has been criticized for its reliability and validity. Use of the performance measures from SERVQUAL to form SERVPERF has addressed some of these issues. However, Magal's instrument on information center success was found effective within a service context because of its service orientation.     

基于SERVPERF模型的我国快递行业服务质量评价指标体系研究

以绩效感知服务质量模型（ SERVPERF模型）为基础,并结合先前学者的研究,利用问卷调查和探索性因子分析设计出由22个指标构成的快递服务质量评价体系,并将它们分别归为移情性、保证性、可靠性、有形性和绿色性5个一级维度。5个维度的命名并不是严格按照原有模型,而是结合实际调查数据分析进行相应调整的结果。其中,移情性除包含原有模型的移情性外还包含保证性;而保证性被重新定义为包含安全性和补偿性的维度。此外,绿色性是一个新添维度。在此基础上,利用因子分析法为22个指标确定权重,得出5个一级维度对整体快递服务质量的影响是不同的,由大到小分别为：移情性、保证性、可靠性、绿色性和有形性。
