ABSTRACT In the present cleaning service industry, service quality is a vital competitive policy to keep customers support and long-term cooperation Cleaning service providers are trying to win customer satisfaction and loyalty by proving enhanced quality service The aim of this study is to examine the relationship between service quality, customer satisfaction and customer loyalty in cleaning service industry In this study, attention is paid to the measurement model of service quality in cleaning service industry based on the well-known SERVQUAL model, but with modification on the basis of focus group discussions and expert opinions to reflect the specific industry attributes and the special culture of Vietnam 158 samples were collected from Pan Pacific Corporation’s various clients in the South of Vietnam Cronbach Alpha was carried out to test the reliability of each statement and the summated scales were formulated by means of Exploratory Factor Analysis (EFA) Then, Multiple Linear Regressions test was used to test the effect of Service Quality on Customer Satisfaction and Customer Loyalty, the effect of customer satisfaction on loyalty Overall findings from this study suggest there were significant relationship between Service Quality, Customer Satisfaction and Customer Loyalty The study found that there were six dimensions of cleaning service quality including affectivity, cleaner competence, supervisor competence, tangibles, service safety, empathy and all dimensions are positively related to Customer Satisfaction The regression test also found that there was a positive direction and significant relationship between customer satisfaction on customer loyalty The results indicated that the overall service quality has significantly positive effect on overall customer loyalty Among these six dimensions except Empathy, all of them have a significantly positive effect on overall customer loyalty Keywords: cleaning service industry, service

Luan an Do an when satisfaction reaches a certain level, loyalty increases dramatically; at the same time, when satisfaction declined to a certain point, loyalty dropped equally dramatically (Oliva et al., 1992) Therefore Pan Pacific should not only focus their effort to improve their Service Quality, but they also need to revisit their service and think how to satisfy their customers When testing relationship between service quality and customer loyalty, our findings confirm that that there was a positive significant relationship between the five cleaning service quality dimensions (tangibles, affectivity, cleaner competence, supervisor competence, service safety) and customer loyalty It also brought out some unexpected outcomes “empathy” one of cleaning service dimensions was not support in their relationship with customer loyalty However, it is difficult to say that empathy dimension is not important in loyalty Further study needs to be undertaken to investigate this problem Once more, by this result the study found that dimensions of service quality are different from service industries, markets and countries In general, the management should primarily focus on customer satisfaction for which service quality is an important antecedent Because the impact of perceived service quality on preference loyalty is considerably strong leading to a more favorable disposition towards the service provider and increased commitment to re-patronize if the Pan Pacific customer satisfied with the service quality offered by them, their customer will be more likely to be more loyal to them In short, Pan Pacific not only to improve their service quality, but they must also look at how to satisfied their customer to retain their customer loyalty This chapter provides the analysis results and main findings of the study Several discussion about the research results are also presented in this chapter The next chapter will draw general conclusion of the study, implications for management, theory and future research 64 Stt.010.Mssv.BKD002ac.email.ninhd

satisfaction, customer loyalty in cleaning service sector As there is no specific model for cleaning service industry in Vietnam so far, this model is the first that provides a clear image of the dimensions that contribute to the service quality in cleaning service industry The primary contribution has been made to enrich the existing theories With regards to research methodology, this study contribute to the marketing literature a measurement scale as a useful instrument to measure quality in cleaning service Vietnam 5.2.2 Practical implications The findings of this study have important implications on the management of cleaning service industry field Cleaning services happen regularly and defining customer’s need and preference, and their related quality dimensions have increasingly become a key driving force in enhancing customers’ satisfaction and attract more customers This study identified a total of six dimensions of service quality Obviously, in order to maintain a high level of overall service quality and to strengthen competitiveness in the extremely competitive market the cleaning service providers should pay attention all these dimensions tested in this study More specifically, the following implications are recommend to cleaning service : Firstly, the findings suggest that cleaner competence and supervisor competence are critical determinants of cleaning service quality, manpower always has a important role in many industries, especially cleaning service Cleaning staffs and supervisor are people who usually work closely with customers every day A

cleaning service provider, so the results might not hold true for other cleaning companies Further research should attempt to replicate the findings in other contexts and more services provider Second, data collection was is limited to customer which have project in the South only, so the findings should not be generalized for all the customers of the entire country Availability sampling is another limitation of the study, However, availability sampling is quite common in the service quality and customer satisfaction literature In addition, the current study not being an experimental one it was not possible to eliminate or withhold the influence of unidentified and undesired extraneous variables from the study Hence, future researchers might consider the recommended studies to draw causal inferences more confidently and safely Finally, theoretically other variables like price perception, corporate image, switching cost etc influence customer loyalty, and including such variable(s) in the study would have made the research models more robust and interesting In future research additional variables should be incorporated 68 Stt.010.Mssv.BKD002ac.email.ninhd
