Problem January 11, 2007, marked an important milestone in the process of economic integration, international when Vietnam officially joined the World Trade Organization (WTO), which is also a prerequisite for Vietnam joined the Treaty of Free Trade (FTA) later, such as the Agreement of Economic Partnership Vietnam - Japan in 2008, the Alliance of Economics Vietnam - Asia-Europe 2015, and most recently Agreement For Comprehensive cooperation & Progress Trans-Pacific (CPTPP) 2018. this was, is and will bring particular benefits in economy, trade and services, empowering Vietnam in the international arena, contribute to promote the export of goods to major markets such as Japan, Australia, as well as to attract external investment into our country. For businesses in Vietnam, here is an opportunity and challenge to them to enhance their competitiveness, improve the quality of goods and service activities to meet the increasing needs of customers if not cut or lose their market share. 294
  2. Kỷ yếu Hội thảo quốc tế “Thương mại và phõn phối” lần 1 năm 2018 In this situation, besides the provision of goods, businesses have to provide additional services to add value for customers. As for the consumer goods industry fast, the enterprise providing services of high quality for distributors play an important role because they are customers, is the decisive factor in sales & prestige of business now, by all means, now have to achieve their satisfaction. Customers (distributors) have very great influence, they can penetrate, drill and intimidation within the enterprise, they have the right to put pressure on businesses in terms of price, quality goods, services, trade discount policy as well as the marketing policy when bringing goods into their system. Unilever Vietnam is one of the leading businesses providing consumer goods with a network of wide distribution, diversity, therefore, to ensure the provision of distribution services with high quality to serve this customer is crucial to the survival of the enterprise. From there, the goods should reach final consumers easier, contribute to improving competitiveness, reducing the pressure of this group of customers to the business. Vo Quoc Huy (2012) also had research on the quality of service delivery activity at Unilever Vietnam, but with the data surveyed in 2011. Also in this study, survey data in 2017, the research context has changed dramatically, the competition in the distribution of goods and services were more severe, authors expect that this study will result found differences alongside the similarities compared with previous studies. From the above problems, the authors believe that the study the influence of the quality components distribution services to the satisfaction of customers at Unilever Vietnam, then consider the impact associated with analyze and assess the status of distribution services at the company in order to make recommendations to enhance the quality of distribution services of Unilever Vietnam is a matter of implementation and reviews means in this context. 2. Theoretical Foundations & research model proposed 2.1. Service Services are acts, processes, and how to perform a certain task in order to create value for customers to use, satisfying the needs and expectations of customers (Zeithaml & Britner, 2000). Kotler & Armstrong (2004), is the active service or benefit that businesses can offer to customers to establish, strengthen and expand long-term partnerships with customers. International Organization for Standardization (ISO), ISO 8402, the service is the result generated by the operation of contact between suppliers with customers and internal operations of the suppliers to meet the needs of customers. There are many concepts of service is expressed in many original varying but generally the service is operating intentionally in order to meet the needs of certain human, characteristics of service does not exist in the form of specific products as commodities that it serves directly for certain needs of society. 2.2. Service quality Service quality ISO 8402 is set according to the characteristics of an object, that object gives the ability to satisfy the requirements stated or implicit. Can understand quality of service is the customer satisfaction as measured by the difference between quality expectations and quality achieved. Feigenbaum (1988), the quality of the decision of the customer based on practical experience with the product or service, measured based on the requirements of the customer, these requirements can be or not stated out, be conscious or simply feel, entirely subjective or professional nature in a competitive market. Lewis & Mitchell (1990), Asubonteng et al (1996), quality of service is a service level that meets the needs and expectations of customers. Edvardsson et al (1994), that quality of service is a service that meets the expectations of our customers, to satisfy their needs. Nguyen Dinh Tho and Nguyen Thi Mai Trang (2003), Bui Nguyen Hung and Nguyen Thuy Quynh Loan (2010), each client often feel differently about quality, so the participation of clients in the development and reviews the quality of service is very important, which is determined based on the perception or their feelings related to individual needs. Parasuraman et al (1988), quality of service is the gap between customer expectations and their perception when used via the service. Parasuraman is considered the first to 295
  3. Kỷ yếu Hội thảo quốc tế “Thương mại và phõn phối” lần 1 năm 2018 research the quality of services specifically and in detail in the marketing field. He explained that for the prediction of the best customer is identifying and understanding their expectations. The development of a system to identify the expectations of customers is necessary, and even then we have a quality strategy for effective service. This can be considered as a most general concept implies full meaning of service and it is also the most accurate when considering the quality of service the customer standpoint, customer centric view. 2.3. The decisive factor in the quality of service Service quality is measured by several factors and accurate identification of these factors depend on the nature of the service and research environment. There are many authors have studied this problem but the most popular and best known are the criteria for assessing the quality of service Parasuraman et al. Model of Parasuraman et al (1988), generalized service quality into 5 specific factors are as follows: 1- the reliability, 2- to meet the, 3- visible means, 4 - capacity for service, 5- empathy. On the basis of research on the quality of service and legacy of Parasuraman theory et al (1988), Do Tien Hoa (2007) has also drawn into 5 other factors of quality of service, including: 1- the considerate, 2- caring, 3- commitment, 4- useful, 5- perfection. 1990, Grửnroos has conducted research and made 6 factors measuring the quality of service as follows: 1. To be professional, 2- competent service, 3- with convenience, 4- with confidence, 5 - credibility, 6- capable of resolving complaints. In 2001, Sureshchandar et al also provides 5 factors affecting quality of service include: 1- the core service elements, 2- human factors, 3- technical factors, 4- factor tangible, 5- community factors. Factors measure the quality of service is determined very diverse vary fields of research. Therefore, the study material is raised above is the basis for the authors refer to the specific identification of service quality scale in the field of fast moving consumer goods. 2.4. Service quality model in the enterprise SERVQUAL model (Parasuraman, 1998) This is the model of service quality research dissemination and applied the most in the marketing research. Accordingly, the quality of services in general can not identify which depends on the customer's perception of the service and the comments are reviewed on many factors. SERVQUAL model is built based on the quality of service perspective feel that the comparison between the expected values / expectations and the value customers perceive. SERVQUAL consider two main aspects of the quality of services is the result service and service providers, has been studied through 21 scale of five criteria: 1- the reliability, 2- response, 3- visible means, 4- capacity serving and 5- empathy. SERVPERF model (Cronin & Taylor, 1992) Model SERVPERF been developed based on the model SERVQUAL but measuring quality of service on the basis of quality assessment services performed rather than the gap between quality expectations and perceived quality. Model FSQ and TSQ (Grửnroos, 1984) According to Grửnroos, quality of service to be considered based on two criteria: functional quality (FSQ: Functional Service Quality) and technical quality (TSQ: Technical Service Quality) and quality of service is affected strongly by business image. Thus, Grửnroos gave three factors affect the quality of service is functional quality, technical quality and corporate image (referred to as model FTSQ). 2.5. Customer satisfaction Spreng et al (1996), customer satisfaction is considered the cornerstone of the marketing concept of satisfying the needs and their wishes. There are many different views on the evaluation of customer satisfaction. The satisfaction of customers is their reaction on the differences perceived between the experiences already know and expectations (Parasuraman et al, 1988), ie experience known customers when using a service and results after the service is provided. 296
  4. Kỷ yếu Hội thảo quốc tế “Thương mại và phõn phối” lần 1 năm 2018 Kotler & Keller (2006), satisfaction is the degree of the state of feeling of a person stems from the comparative perception of a product compared to expectations of that person, satisfaction with three levels is felt received not satisfied, feel satisfied, feel as satisfying and enjoyable. Kano (1984), each customer has 3 levels of needs: basic needs, needs expression, latent demand. A common theory for review of customer satisfaction theory "Expectations - Confirm". The theory was developed by Oliver (1980) and is used to study customer satisfaction with the quality of the services or products of an organization. Theory consists of two processes independent small impact to customer satisfaction: service expectations before purchasing this service and feel after the experience. Through review of the researchers could see customer satisfaction as the impact on the target, the development strategy of the company. Satisfying customer needs is critical in efforts to improve service quality, enhance competitiveness. Customer needs are met is an important element to maintain long-term success of the business and business strategy suited to attract and retain customers (Zeithaml et al, 1996). 2.6. The relationship between service quality and customer satisfaction The relationship between service quality and customer satisfaction is the theme given researchers a lot of discussions. The majority of research on customer satisfaction in the service sector has been made, generally concluded that the quality of service and satisfaction are the two concepts are differentiated. The satisfaction of customers is a general concept to express their satisfaction when consumers a service, also said the quality of service is of interest to the specific components of services (Zeithaml & Britner, 2000). Oliver & Westbrook (1993), quality of service affects the level of customer satisfaction. Quality of service is determined by many different factors, is a decisive factor section of satisfaction (Parasuraman, 1988). Many studies practical relationship between service quality and customer satisfaction. Cronin & Taylor (1992) has tested this relationship and concluded that the perceived quality of service leads to customer satisfaction. The study concluded that quality of service is the premise of satisfaction and is a key factor affecting satisfaction, want to improve the satisfaction of customers, service providers must improve the quality of services service. In other words, quality of services and satisfaction of customer relationship a mutual, closely together, in which quality of service is what was created first and then decided to the satisfaction line. Causal relationships are key issues in most of the research on customer satisfaction. 2.7. Distribution services Distribution of marketing activities is a concept of business, to guide and implement the transfer of ownership between sellers and buyers, while implementing the organization, conditioning, coordination organizations middle different time ensuring that goods reach and maximum exploitation of all kinds of market demand. Distributed as intermediaries important in the process of circulation of goods, with nature is changing the geographical location of the goods, as a bridge between producers and consumers, creating a mismatch between supply and demand. So distribution activity is created for social services: - Reduce transaction cost savings, achieve satisfaction in the best way. - Implement improvements merchandise uniform designs, overcoming limitations of commodities, technical and financial aspects of each individual manufacturer. - Consumers easily find products, they become closer to them. 297
  5. Kỷ yếu Hội thảo quốc tế “Thương mại và phõn phối” lần 1 năm 2018 - Goods consuming, require intermediary distribution system to ensure the goods are circulated quickly. 2.8. Service quality measurement 2.8.1. Model service quality measurement 5 component model service quality the scale SERVQUAL is servqual popular model and is used extensively in the marketing research, are very useful in generalizing the measure of service quality. Authors select models SERVQUAL model theory in the study of the influence of the quality of service to deliver to the customer's satisfaction. The scale SERVQUAL to measure the perception of the services through five service quality components, including reliability, responsiveness, service capacity, empathy & visible means. Parasuraman et al (1993) assert that the scale SERVQUAL complete service quality and reliability are applied to all types of different services as well as in many different markets. However, results of inspection of the fact that quality of service is not consistent with each other in each of the services and the different markets where it has to be adjusted to suit each type of service and each regional market. Such as Dabhokar et al (1996) have built scale 5 components of retail service quality in the supermarket: 1- visible means, 2- reliability, 3- waiters, 4 - resolve complaints, 5- policy store. Lobo et al (2000), when studying the retail services of electronic goods in supermarkets in Singapore, offering quality service model adjustments, consisting of 5 components: 1- The service staff, 2- facilities, 3- cargo, 4- trust, 5- parking lot. Nguyen Dinh Tho and Nguyen Thi Mai Trang (2003), study quality of service supermarket customer's perspective, the model also includes five components: 1- The commodity, 2- capable of serving staff , 3- exhibited in the supermarket, 4- the supermarket premises, 5- safe in the supermarket. Nguyen Dinh Tho et al (2003) tested SERVQUAL market area outdoor recreation in HCM city, service quality consists of four components: 1- the reliability, 2- service capability employee, 3- exhibited in the supermarket, 4- the supermarket premises, 5- safe in the supermarket. Nguyen Dinh Tho et al (2003) tested SERVQUAL market area outdoor recreation in HCM city, service quality consists of four components: 1- the reliability, 2- service capability employee, 3- empathy, 4- visible means. Depending on specific characteristics of the types of services fast moving consumer goods distribution, the author will adjust the scale SERVQUAL to suit the characteristics of fast moving consumer goods industry in this particular study. 2.8.2. Features of distribution services fast moving consumer goods Distribution service is a service consumer goods distribution. The difference between the distribution of consumer goods with other products is on the consumer, customers use every day in large numbers, it is to be right, therefore, to ensure the goods are always present at the point of sale is the paramount duty of a distribution system. Besides for consumer products, other companies in the same field are similar products on the market in terms of type and features. Eg laundry detergent Omo (Unilever) and Tide (P&G), fabric softener Comfort (Unilever) and Downy (P&G), Rexona and Romano, Safegard and Lifebuoy , so the risk of the product being replaced is very high, demanding ask the service distribution companies to ensure fast, accurately with high reliability to increase capacity to meet the investment and relentless research of new product. Also, according to the specific characteristics of the fast moving consumer goods sector, the company's customers are not just consumers, but rather half of those distributors. These customers are of considerable importance, they can drill and threatened even within the company, they have the power to influence the price and quality of products as well as marketing policy when put products into their systems. Especially in the retail channel modern companies suffered a small pressure, so the distribution services of the company bearing the task of paramount importance, not only to meet the expectations of customers goods but also empowering for distributors. 298

In summary, all of the data collected is very good, ensuring standards in research using SPSS 20.0 software. Results achieved high reliability, based on the results of the regression analysis, the author will discuss and give implications to enhance the quality of product distribution services of Unilever Vietnam.  Discuss The degree of influence of the components in the quality of service to deliver to the customer's satisfaction expressed by the following equation: SHL = 0.344*PTHH + 0.302*TTC + 0.431*TDU + 0.331*DVHT + 0.229*TPSP + 0.265*NLPV + ε a. Visible means: has the 2nd strongest influence satisfaction with β = 0.344 customers (at 18.1% affected). As production facilities, factories, offices, administration, in this study, the visible means primarily be regarded as the truck delivered to distributors, ensuring aviation malfunctioning, loss. Visible means indirectly increase the reliability, responsiveness and service capacity of staff in the transaction process and thereby increase the satisfaction of customers for distribution services of company. b. Reliability: affecting customer satisfaction ratings has the 4th strongest influence with β = 0.302 (the impact of 15.9%). How it works, the safety of transactions, compliance with the commitments set out to bring satisfaction to our customers. In the distribution of products, the benefit of the customer associated with the interests of the Company, particularly the interests of the customer depends on the company when the company holds the prestige of the commitment to the customer and security ensure mutual benefits. c. Responsiveness: affect the customer's satisfaction with β = 0.431 strongest (22.7% respectively). In the present time, the competition between the industry players are great as well as the pressure has been replaced by a business other supply or by a new product is very high, so the responsiveness bring customer confidence. With the characteristics of fast moving consumer goods products are consumed daily in large numbers, the more responsive shown significant role in winning the trust of customers. 306
  14. Kỷ yếu Hội thảo quốc tế “Thương mại và phõn phối” lần 1 năm 2018 d. Support Services: affecting customer satisfaction ratings has the 3rd strongest influence with β = 0.331 (corresponding to 17.4%). This speaks to the importance of support services for customer satisfaction when dealing with Unilever Vietnam. With distinct characteristics of the consumer goods industry fast, maybe due to the diversity and complexity of products has made it difficult for customers during transactions with the company, so the service customer support is indispensable, the real benefit to customers. In addition, support services help increase the competitiveness of companies in the market and strengthen the link, the customer depends on the company. e. Ingredient production: has the lowest influence satisfaction with β = 0.229 (corresponding to 12.0%). Customer focus on product quality, variety to meet the needs of increasingly rich and more selective market. Diversity in types, quality as well as improving the availability of products in the distribution chain will help both companies and distributors will be competing significantly in the market compared with the same products . f. Service capabilities: affecting customer satisfaction ratings has the 5th strongest influence with β = 0.265 (corresponding to 13.9%). May be due to many competing firms should be capable of serving the employees of the company have been enhanced to meet customer needs, so please do not differ too greatly between service capacity of the company and rivals. Employees who work directly with clients, across from the access to end the transaction, are exposed to solve the problem of after-sales, billing, claims To improve satisfaction customer first companies to have policies to improve in order to improve the satisfaction of the employees of the company, focus from recruiting, training, professional services, business ethics for them, this is an important tool to bring satisfaction to our customers. Compared to research in the field of distribution of fast moving consumer goods at Unilever in 2012 by Vo Quoc Huy, there are some similarities and differences in results as compared with this study may be due context researchers have different economic environment, social change, including product and business policy of the company and distributors, this could lead to a change in judgment about the quality of service distribution customers. Specifically, according to Vo Quoc Huy (2012), components visible means does not affect the customer satisfaction, reliability with the influential 4th (β = 0.219), responsiveness has the 2nd strongest influence (β = 0.333), the impact of support services is the lowest (β = 0.117), ingredient production has the effect 3rd (β = 0.226) and service capabilities levels strongest influence (β = 0.650). Continue comparable studies on the impact of service quality to customer satisfaction, we can recognize in each different service areas will have different results. Specifically, the field of hotel services (Le Huu Trang, 2007), factors that most influence the calculation task (0.515), feedback (0.254), reliability (0.120) and visible means (0.117). The field of real estate (Pham Van Hai, 2011), factors capable of serving staff (0.484), support services (0.314), reliability (0.286), the product (0.283) and safe (0.244). Two studies are used as the basis SERVQUAL, but the results are different, feel different customers about the factors affecting their satisfaction. Therefore, we can see that the components of the service quality is not stable, depending on the field of study and research environment, in areas different services, the customer's perception of quality of the service that will be different. 3.4.
