    A. RESEARCH PLANI. RESEARCH OBJECTIVES AND PLAN

    1.1: Research objectives

    According to Porter, Competitive advantages give a company an edge over its rivals and an

    ability to generate greater value for the firm and its shareholders. The more sustainable the

    competitive advantage, the more difficult it is for competitors to neutralize the advantage.

    (Porter, n.d.)

    There are two main types of competitive advantages: comparative advantage and differential

    advantage. Comparative advantage, or cost advantage, is a firm's ability to produce a good or

    service at a lower cost than its competitors, which gives the firm the ability sell its goods or

    services at a lower price than its competition or to generate a larger margin on sales. A

    differential advantage is created when a firm's products or services differ from its competitors

    and are seen as better than a competitor's products by customers.

    This study will show that customers awareness, products/services of Yamaha company and

    market demand. Following will be overall and specific research objective:

    To identify advantages and disadvantages of scooters Yamaha compared with

    scooters of other bands.

    To identify relationship between customerss perception with Yamaha.

    To determine the effectiveness of scooters of Yamaha.

    The subject is focused to research which is scooter Nouvo of Yamaha.

    1.2: Plan of collecting primary data

    The researchers will use primary data and secondary data. Primary data is data which is

    collected and observed directly by user throughout the study process. Secondary data is data

    which is collected not by user, but by someone else for users aims. Secondary data will be

    II. SURVEY METHODOLOGY AND SAMPLING METHODS

    2: Survey Methodology and Sampling Methods

    2.1: Survey Methodology

    Questionnaire

    The questionss content and the answers of customers are the primary means to collect the

    data. Therefore, the main purpose of this survey is learning more about the feedback of

    customers whether they feel satisfied or not. There are 100 volunteers to answer the research

    questions. Questionnaires focus mainly on the behavior of the customers toward company

    which were given to customers of Yamaha in Hanoi. The researchers came to Royal city to

    give respondents of customers.

    The questionnaire had 23 questions. They were divided into 3 parts: personal profile,

    information of product researched "Nouvo" and the assessment about Yamahas products and

    services by factors of competitive advantage.

    Through 23 relevant questions, the researchers will collect the information needed to clarify

    the concept, and the degree of satisfaction of Yamaha's customers with products and services

    in the interests competitive edge. Since then, the impact of competitive advantage of Yamaha

    will be evaluated.

    2.2: Sampling Methods

    To carry out the survey and data collection, the researchers have used sampling methods

    are classified as either probabilityor nonprobability. In probability samples, each member

    of the population has a non-zero probability is known to be chosen. Probability methods

    include random sampling, the sampling system and stratified sampling. In nonprobability

    sampling, members are selected from the population in some nonrandom way. (statpac, 2012)

    Each method has its own advantages and disadvantages and the researchers must have an

    understanding of this to choose the right method in accordance with the survey. In our

    situation, we select a random samplethat is "a sample selected in such a way that all items

    in the population have an equal chance of being included." (BBP, 2010). We chose this

    method because it is a simple technique that allows us to conduct the survey with customers

    that we met. Moreover, it can save our time and costs. Also, if all the requirements provided a

    model then the answer would be the high representative.

    Research sampling is about the way that researchers use for selecting 100 customers as

    respondents to make a typical result for the whole customers using Yamahas services. The

    researchers did surveys 100 customers in the Royal City.

    III. DESIGN A QUESTIONNAIRE AND EXPLANATION3.1: Questionnaire layout

    Customer awareness is one aspect of development strategy reflects the company's success

    in the market. Therefore, conduct regular surveys play an important role in the development

    plans of the company to meet customers goods. We tried to design an appropriate

    questionnaire to survey an effective and successful research. following is a question and our

    explanation for it. The questionnaire is designed on one A4 page including 23 questions

    divided into 2 main parts:

    Part 1(from question 1 to 6): Respondents profile includes gender, age, productNouvo are being used, time used and knowledge about Nouvo.

    Part 2 (from question 7 to 23): Assessment of the influence of competitive advantagebased on 3 factors: design, service, payment price.

    3.2: Response format

    From question 1 to question 6 is questions about customers profile. It helps researchers

    identify demographic information of respondents who using and have ever used Nouvo of

    Yamaha company. Those questions help the researchers understand more respondents to

    easily assess awareness and behavior of respondents based on their demographic matters.

    From question 7 to question 23 are the questions which research about influence of

    competitive advantage. we apply likert scale for 8 questions: 9, 14, 15, 16, 17, 19, 20 . For

    example, for question about the level of satisfaction of Yamaha Nouvo, we apply likert scale

    to express 5 levels of evaluation, including Very dissatisfy (0-1), Dissatisfy (1-2), Normal (2-

    3), Satisfy (3-4), and very satisfy (4-5).

    Coefficient of determination

    An equation of a straight lines has the form: y = a + bx

    We have an equation of line following: y = 4.3607 + 0.3311x

    c. InterpretationThe correlation coefficient () is 0.35; it means that the correlation between the quality of

    items and the price of items is positive partial correlation; however this correlation is very

    low. Besides the co- efficient of determination (is about 0.125. basing on this result, wecan see that there are about 12,5% quality of product is shown on the price of items, so that

    the 87,5% of quality is represented in other elements.

    d. ConclusionBased on this correlation, we can say that the close relationship between the quality of the

    goods and the prices of commodities. If the quality of items is good, cozy up to the user, the

    company will receive the price accordance with goods

    e. RecommendationIt is important for Yamaha to improve the correlation between the quality of items and the

    price of items. The firm should focus on designing to create more design, functions,.. to

    attract more and more new customer and remain existing customers. This thing can help the

    firm achieve better positive partial correlation.

    Coefficient of determination 64 An equation of a straight lines has the form: y = a +bx

    We have an equation of line following: y = 2.9031+ 0.589x

    d. InterpretationThe calculation shows that the correlation between the Price of Nouvo and price of

    accessories of Yamaha. Because r = 0.506, so it is a positive correlation means that the gold

    conversion prices in the game is not too expensive so the money to pay for the items in thegame are not high, but it is too low correlation. On the other hand, the coefficient of

    determination (r ) is 0.2564. It means that 25% of customers rated the value of items that can

    be explained by evaluating the price of Yamaha, while 80% left evaluate the price for

    accessories can be explained by the other factors.

    e. ConclusionBased on this correlation, it can be said that the close relationship between the price of

    Nouvo and price of accessories of Yamaha . Only when the price of nouvo is cheap, the price

    of accessories are also cheap, so customers will have conditions to buy accessories to

    decorate their Nouvo.

    f. RecommendationTo enhance the relationship between price of product and the price for accessories in

    Nouvo, Yamaha should focus on the price set in Nouvo are not too high. So that will appeal

    to players buy those items.
