competitive environment and widely used by the retailers as one of the important strategy because of its impact on customer satisfaction The retailing industry plays a crucial role in the overall economy of Viet Nam By satisfying customers through high quality service, business firms not only retain their current customers, but also increase their market share (Finn and Lamb, 1991) By the way, retailers have positioned themselves for all kind of customer needs and income levels especially the growing young working population Many retailers have been upgrading themselves by relocating to up-coming modern malls and shopping centers, providing superior shopping atmosphere and experience especially in the urban and semi urban centers To date, many studies on service quality relied on service quality construct and scale by Parasuraman et al (1988) However, this application to the retail industry may not be appropriate for service quality in retailing industry, as well as not clear enough whether these retailers have fully embraced the retail concept which emphasis on proper communication, total retail experience, customer service, relationship retailing and consistent strategy Additionally, the retailers are more forced to concentrate towards customer’s perception in the competitive environment One of typical characteristic in retail setting, especially retail stores where there is a mix of product and service, retailers are likely to have impact on service quality more than on product quality (Dabholkar et al., 1996) As retailers can create such effects, service quality plays a significant strategic role in creating quality perceptions In this, the marketing decisions revolving around the target market, product assortment, services and store atmosphere, store activities and experience, procurement, price decisions, communications and location decisions which are very critical to a retailer’s success should be emphasized (Kotler & Keller, 2006) Recently, the growth in importance of service quality in the world has been influenced greatly by the changing nature of the world economies and the customers changing needs, tastes TIEU LUAN MOI download5 : skknchat@gmail.com and preferences The move has also been fueled by the growth in consumerism, world travel and the competitive business environments The service quality has become a key concept in a competitive corporate strategy (Gronroos, 2001) However, there have been very few studies on retail service quality in Vietnam, especially the comparison between supermarkets and convenience shops Therefore, the research on perception of service quality within convenience shops and supermarkets in Viet Nam is necessary to show out an overall picture of retail service quality in Viet Nam Hence, the question is how to evaluate customer’s perception of service performance within the retail stores that needs to clarify timely and pertinent because perceived performance could influence the retail stores image, customer satisfaction and bottom-line growth 1.1 Problem statement Recently, many firms have come to realize that understanding, meeting and anticipating customer needs is probably the most important source of sustained competitive advantage (Vilares & Coelho, 2003) Especially, in-depth knowledge of how to satisfy customers is very important in developing countries such as Viet Nam, where small convenience stores are struggling to compete with large supermarkets that are expanding to sub-urban areas and elsewhere In order to gain the competitive advantage and increase organizational effectiveness, the improvement of service quality is required and needed to be paramount to focus attention, because that is only the way to make a differentiation Excellent customer service may indeed be the best answer to countering the increasing trend of the expansion of supermarkets The retailing sector has been the focus of much academic research and considerable attention have been directed to the way consumers think and feel about stores making up their attitudes and perceptions towards the stores In the world, there are some researchers have researched about this such as Ed Watkins (1976) researched on factors influencing choice of supermarkets and convenience stores to develop a marketing strategy for each, while Ryu and Han (2010) investigated the influence of quality food, service and physical environment on customer satisfaction and behavioral intention in TIEU LUAN MOI download6 : skknchat@gmail.com quick-casual restaurants in Midwestern state This study is aimed to explore the components of retail service quality in term of supermarkets and convenience shops in Viet Nam, as well as the relationships between each of retail service quality components and customer’s overall evaluation of retail service quality This study is also to assess shoppers’ perceptions of the quality of service provided by the convenience shops and the supermarkets in Viet Nam Specifically, this research is to find the pertinent answers to the following questions: What are the key factors of retail service quality (convenience shops and supermarkets)? What shoppers generally consider important while shopping in a retail store? 1.2 Research methodology and research scope The survey questionnaire is originally developed in English and then translated into Vietnamese In-depth interviews are then conducted with five convenience shoppers for each area including supermarket/ convenience shop in order to modify the Vietnamese version of the questionnaire before the survey is implemented in mass The next step is analyzing the collected data The data of this research is processed using SPSS software with three main stages First, Cronbach‟s Alpha is used to test the reliability of the measurement scale Then, the validity of the measurement scale will be checked by Exploratory Factor Analysis (EFA) Finally, simple regression and multiple regression are employed as the main method for investigating the relationships among factors in the research model Ho Chi Minh City has been chosen to conduct the survey for this study since it is one of the biggest cities in Vietnam and most of international brands centralize here Moreover, Ho Chi Minh City is also one of the wealthiest cities in Vietnam, so people who live here will have higher chance to visit supermarkets and/ or convenience shops, which are usually quite often 1.3 Research contribution This research complements and adds to previous research by expanding the study of retail service quality to include supermarket and convenience shop with the comparison Therefore, this TIEU LUAN MOI download7 : skknchat@gmail.com study is very important because it offers a scale to measure service quality that is suitable for supermarkets and convenience shops and which could be modified slightly to expand whole retail industry Based on findings in the end of this research, we hope to provide practical contributions to the retail service quality industry, particularly to owner of supermarkets and/ or convenience shops who have the intention to develop their business, especially enter Ho Chi Minh City market However, it is essential for owners of supermarkets and/ or convenience shops to find out effective strategies that can maximize opportunities and minimize obstacles This study with deep understanding of consumers’ intent to use supermarkets and/ or convenience shops can help their owners have a higher chance to be successful in Ho Chi Minh City market In summary, the findings of this study would be useful for retail brand marketers who want to penetrate the business in Ho Chi Minh City and who have already developed in the market and want to maintain the loyalty of their customers 1.4 Research structure This study is organized into five chapters It starts with the introduction chapter which presents an outline of this research This chapter includes background of the research and research objectives Besides, the significance that this study contributes to management practice as well as scope of the research and methodology of data analysis are also mentioned in the first chapter Chapter two reviews and synthesizes the theories in the literature of five concepts, including physical aspects, reliability, personal interaction, problem solving and policy This chapter also describes research model and proposed hypotheses Chapter third introduces research methodology used to empirically test the research model Chapter four presents the results of data analysis The final chapter discusses summarily the study’s core findings, suggests some recommendations for business strategy of retail companies based on findings and finally points out some limitations of the research TIEU LUAN MOI download8 : skknchat@gmail.com CHAPTER 2: REVIEW OF LITERATURE This chapter presents a review of relevant literature related to factors affecting customer’s perception in comparison between supermarkets and convenience shops This chapter also states the hypotheses and propose conceptual model for this study 2.1 Service quality and customers’ perception of retail store service Service quality is a critical component of customer perceptions about the service as retailers provide both goods and services to their customers Retailing has been characterized as a service with high degree of labor intensity, and low degree of interaction and customization (Tan & Mehta, 1994) Examples of retailers in Viet Nam include the supermarkets and many others of small shops such as kiosks (very small convenience shop), hawkers, butcheries, fuel stations, bookshops, hotels, chemists, ordinary shops, auto dealers, cloth stores, jewelry stores, gift shops, shoe shop, furniture stores, music stores, etc As thus, the service quality is defined as customers’ perception of how well a service meets or exceeds their expectations (Czepiel, 1990) By growing the research in the service quality, it has made many retailers to understand the importance of service quality in their retail offerings As mentioned earlier, positive customer’s perception of service quality can greatly influence a firm’s performance and competitiveness Customer’s perception has been defined as a customer’s overall impression of the relative inferiority/superiority of an organization and its services (Bitner & Hubbert, 1994) This perception is influenced by many factors such as employee’s performance, facilities, price of products and quality of service offered among other factors Further, due to technological developments of education, customer’s perceptions are greatly changing and calling for organizations to have concerted effort to understand these perceptions On the other hand, retail image refers to how a retailer is perceived by customers and other parties According to Berman and Evans (2005) overall retail image is influenced by store location, merchandise attributes, pricing, firm’s positioning, customer service, target market, attributes of physical facilities, shopping experience, TIEU LUAN MOI download9 : skknchat@gmail.com promotion tools (such as advertising, public relations, personal selling, sales promotion) and community service Further, Berman and Evans (2005) note that a retailer's image depends heavily on its ‘atmosphere’ or the psychological feeling a customer gets when in that retail outlet 2.2 Review of Service Quality Models Service quality in retail outlets is different from other product or service oriented organizations (Finn, 2004) Service quality is considered as the most vital performance indicator of an organization in both the marketing literature usually and the service marketing literature particularly A number of models of service quality have been developed A review of service quality scales of retail by Wang (2003) indicates that the two most widely used scales are the SERVQUAL developed by Parasuraman (1988) and RSQS developed by Dabholkar (1996) On the application of SERVQUAL within retail setting, in 1980s, in the attempt to define the service quality as well as to develop a model of service quality affecting customer satisfaction, Parasuraman conducted an exploratory investigation The results showed that regardless of the type of service, consumers used the similar criteria in evaluating service quality (Parasuraman et al., 1985) In deep of review, Wang noted that SERVQUAL fails to provide a precise and efficient measure of service quality in retail settings such as discount stores and apparel specialty stores that offer a goods and services Wang found that there is a broad variety of experiential factor structures that can be obtained which vary in terms of interpretability thus conflicting from five factor structure Reliability, Assurance, Tangibility, Empathy Responsiveness proposed by Parasuraman (1988) This model indicates that consumer perceptions of quality influenced by five gaps occurring in the internal process of service delivery The basic premise is that service quality could be defined by the difference between expected service and perceived service (Parasuraman et al, 1985) By looking at that model, we can see that the first four factors are those on the service provider side of service (organization side) The last factor (Empathy Responsiveness) relates to the customer side of service However, SERVQUAL applies in the study of different types of TIEU LUAN MOI download10:
