chapter begins with general introduction about cleaning service and the current study is provided with research background, research problem, research objectives and research questions are mentioned as the rationale for this study Also, scope of the current study are discussed and an introduction of the methodology to be used in this chapter At the end of the chapter, the structure of this study is provided 1.1 Introduction about cleaning service industry Nowadays, cleaning service is very popular in human life Cleaning service providers is responsible for providing all necessary management, manpower, machinery, equipment, tools, chemicals (exclusive such items, which the Landlord shall provide), which were pre-approved by the Landlord to efficiently carry out the cleaning tasks of the project in accordant with the international standard and Landlord requirements They also provides uniformed, properly trained and appropriately skilled cleaners All cleaners have a yearly health check Cleaners shall at all time while on duty be dressed in full uniform, well groomed, cleanshaven, polite and helpful Service providers maintains the minimum number of contracted cleaners and provides additional cleaners as it determines necessary for full cleaning coverage during sickness, holidays, etc Using cleaning service bring to us much advantage : high quality service, reasonable fee, the professional and well trained working force from the leading company in cleaning and property care, the modern specific cleaning equipments without any investment, maintaining the value of the property, creation a clean and beautiful working environment for both officers and visitors, avoidance from directly management to the cleaning workers and risks from its potential problems, whole hearted concentration on own business TIEU LUAN MOI download : skknchat@gmail.com Among of many cleaning service providers in Vietnam, Pan Pacific is one leading company in this industry, with operating in over 20 cities and provinces nationwide, supplying cleaning service for more than 300 customers of many business types Pan Pacific also is among of Vietnam largest cleaning providers with over 5000 skilled employees With more than 17 years experience in cleaning service industry, Pan Pacific has developed various customer system including Commercial Buildings (office buildings, service apartments), Supermarkets and Shopping Centers, Hospitals & Medical Centers, Factories in IPs, EPZs, International Schools Especially, Pan Pacific also have many experiences in supplying regular cleaning service for typical projects with highest level national security such as; International Airports, Television Station 1.2 Research background: Going with developing real estate market and foreign investment, demand of facility management in office buildings, shopping centers, international schools, foreign factories are appeared These management services include security, property maintenance, pest controls, landscape and cleaning service In which cleaning service industry is very important to enhance quality and brand of the building Instead of organizing and managing a cleaning division, owners can contract with professional cleaning company which can provide package service including manpower, equipments, tools, chemicals A cleaning company will provide uniformed, properly trained and appropriately skilled cleaners, all cleaners have a yearly health check, cleaners shall at all time while on duty be dressed in full uniform, well groomed, clean-shaven, polite and helpful Cleaning company will provide additional cleaners as it determines necessary for full cleaning coverage during sickness, holidays, etc Cleaning company also is responsible compensating damage of property which cause of their employees TIEU LUAN MOI download : skknchat@gmail.com 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 TIEU LUAN MOI download : skknchat@gmail.com Chapter 5: CONCLUSIONS AND IMPLICATIONS The previous chapter presented the analysis results and the main findings of the study At the end of chapter 4, a modified model was also proposed In this final chapter, summarized all hypotheses that will be used to answer for the research questions of this study and general conclusion will be drawn At the end implications for management, theory and future research will be addressed 5.1 Conclusions of the study Based on the findings in the chapter 4, the present study determined that there are six dimensions of cleaning service quality and their prioritization are cleaner competence, supervisor competence, affectivity, tangible facilities, service safety and empathy This result is the answer of research question The study also examined Pan Pacific Corporation’s customers via survey questionnaires, data analysis, trying to figure out relationship between service quality, customer satisfaction and customer loyalty in cleaning service industry The result showed a significantly positive relationship between overall service quality and customer satisfaction In additional, all service quality dimensions have a significantly impact on customer satisfaction Similar to examine relationship between service quality and customer satisfaction, analysis outcome presented there is a significantly positive relationship between cleaning service quality and customer satisfaction However, all service dimensions have a significant impact on customer loyalty except “empathy” The research question is supported The study also found that, there is a significantly positive between customer satisfaction and customer loyalty 65 TIEU LUAN MOI download : skknchat@gmail.com 5.2 Implications of the study 5.2.1 Theoretical implications The main purpose of this study is to gain a better understanding of relationship between service quality, customer 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 supervisor has good managerial skills, action attitude will keep the cleaning quality as standard, flexible in solving arising issues during providing cleaning service of 66 TIEU LUAN MOI download : skknchat@gmail.com supervisor always lead to customer satisfaction and loyalty Cleaning team with good working skills, devotion attitude is always enhance a professional image of cleaning company in customer eyes, improving brand of the buildings Cleaning service companies should have professional management, good recruit and training system New cleaner should have well training before starting the works at sites Secondly, affectivity dimension which is representative of reliability and responsiveness side respect also has a key role in cleaning service quality Cleaning companies have to provide service as obligation and have prompt response to crisis, issues caused during the process of cleaning and also unforeseen customer emergencies To meet this requirement, cleaning companies not only focus on service personnel as above mention but also should have professional organization with closely coordinate between function departments, especially Sales and Operation Department The affectivity or responsiveness service dimensions implies that cleaning company should have immediately corrected actions when receiving complaints from customers Thirdly, tangibles and service safety dimensions contribute to customer satisfaction and loyalty Customers feel secure in using cleaning service with modern equipment, good tools and especially chemicals which are not effect to environment and properties Paying attention to these factors keep the property of landlord stably, showing professional image Finally, empathy was is assessed less important than others, but it is necessary component in cleaning service A good relationship with clients will let them share their thought about service quality This will help cleaning service providers correcting the issues immediately to satisfy customers 67 TIEU LUAN MOI download : skknchat@gmail.com 5.3 Limitations and recommendations for further research The findings of this study have to be interpreted considering few limitations First, data were collected only from a single 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 TIEU LUAN MOI download : skknchat@gmail.com APPENDIX 1- CUSTOMER SATISFACTION FEEDBACK
