Service Guarantee Strength: The key to service quality

Abstract

While most authors describe a service guarantee as a ''zero-one variable'' indicating the presence or absence of an explicit written service guarantee, this paper develops a construct called ''Service Guarantee Strength'' (SGS) that is a continuous variable. This construct measures the degree to which a firm sets clear service quality standards for itself on dimensions that customers care about, and has an formal policy for quickly giving meaningful compensation to customers when these standards are not met.The paper builds upon established micro-level behavioral theory to develop the ''Service Guarantee Strength Framework''. This framework posits that high Service Guarantee Strength leads to improved service quality, customer satisfaction, and loyalty through three intervening variables-marketing communications impact, employee motivation and vision, and learning through service failure.An empirical investigation was conducted to test the SGS Framework using both employee and customer data from three pairs of firms, with each pair in a different industry. None of these firms had an explicit service guarantee. Unlike many behavioral research studies, this study measured both employee and customer perceptual data and compared the two. The research finds that Service Guarantee Strength is positively related to customer perceptions of service quality, customer satisfaction, and loyalty. #

The impact of high-performance work systems in the health-care industry: employee reactions, service quality, customer satisfaction, and customer loyalty

“…In the study, the measurements for customer satisfaction were modified based on the previous studies of Parasuraman et al (1988), Homburg and Stock (2004), Chung and Lee (2005), Hay and Hill (2006), Friesner et al (2008), and Yee et al (2008). This study adapted measurement items of the customer loyalty suggested by Chung and Lee (2005) and Hay and Hill (2006).…”

“…This study adapted measurement items of the customer loyalty suggested by Chung and Lee (2005) and Hay and Hill (2006). Figure 1 shows the proposed research model describing how health-care HPWS affect employee reaction, service quality, customer satisfaction, and customer loyalty.…”

Relationship between the Star and the Hotel Service Guarantees of Customer Satisfaction

“…The instrument used was the common measurement behavior with scales and questionnaire method adapted from the work of Hays and Hill (2006), Shahril (2014), Aziz (2007) and Severt (2002) with the reliability or Cronbach's alpha for the questionnaire ranges above 0.8. These researchers work was adapted for this study because of their considerable researches in the field.…”

Evolution of Online Social Networks: A Conceptual Framework

“…Whereas fragmented relationships, which amounted to simple information trading, constituted the principal relationship in the Web 1.0 era, network-based interaction becomes dominant in Web 2.0 and after. Information system researchers claim that, if OSNs are limited to establishing friendship between users with similar interests or people who know each other, requirements have recently been proposed for the vitalization of online communities and the expansion of their influence and lifestreams (Ebling et al, 2002;Hays & Hill, 2006). They also see a change in that communities centered on core users understand and accept the social embeddedness of individual constituents.…”
