CHAPTER I - INTRODUCTION

1.1 Company Introduction

The company in case, PGFV Ltd Company is a Vietnamese startup company which was found in June 2014 The company is located in Ho Chi Minh City, Vietnam Its original business was not related to IT as well as Internet Recently, the company was launched an online service, Sunmall.vn, in order to enter the Internet market The main idea of the service is to provide the premium product from different

brand from Korea for customers; it tries to provide the better service and product

quality to customers

The issue in this case is that there are many companies doing e-commerce but they are unsuccessful for many reasons such as: lack of capital, poor marketing strategy,

lack of skill and experience, insufficient market research, no website traffic In

addition, online purchasing is also not a common method of buying goods and services in this country Buying online is somehow untruthful to consumers and people would like to pay in cash and have a look at the product before buying These behaviors prevent people to get used to online shopping

| Currently, there are two big cities in Vietnam, which are Hanoi, the capital, and Ho Chi Minh city, the biggest city located in the South Both have the population of more than 15 million people and are the main markets of online shopping business (tuoitre.vn) Currently, sunmall.vn operates in Ho Chi Minh City with more than 50 types of products in supply network There are many big competitors, who have succeed in the industry such as: Lazada, chotot, vatgia, etc The market is getting tougher as new comers are entering In which, there are some big players in online service business not only in Vietnam but also in the world Therefore, the challenge for Sunmall.vn is quite high ,

organizations and actually it is a powerful source to use (Hamill, 1997; p.300)

‘The Internet have been using for several different purposes Besides that, it has also brought a different dimension to commercial activities The Internet has created a new market for both customers and organizations, and has been an alternative market

to the traditional market Web sites provide a chance to search information about products/services, place a comment or give orders (Hoffman and Novak, 1996; 51) Therefore, the previous experiences of marketing has turned into a different segment

Now organizations are taking consider to provide different payment methods,

different shipping alternatives and even different web interfaces for different geographic ,

CHAPTER II - LITERATURE REVIEW

Customer satisfaction can be viewed as a relationship of perceived value of service

and the expected value by customers If the perceived value of services matches

customer perceived expected value, then customer is said to be satisfied Kotler and

Armstrong (2013: P37) define customer satisfaction as “the extent to which a product’s perceived performance matches a buyer’s expectation.”

2.2 Overview Marketing 7Ps

2.2.1 7Ps Marketing History

According to Dr Philip Kotler, marketing mix is defined as a set of tools and tactical

marketing that companies collaborate to create the desired response in key markets (Kotler and Armstrong, 2004)

The concept of marketing mix proposed in the Conference of the American Marketing Association (American Marketing Association) 1953 by Borden and started and become popular in 1964 after he published articles "The concept of Marketing-Mix" From the 12 components of the Borden’s marketing mix, E.Jerome McCarthy (1960) shaped model systems 4Ps: price, product, distribution and promotion Sometime later, Booms and Bitner (1981) added 3 Ps (people (People), service process (Process) and tangible media (Physical Evidence) to form the original 4Ps to model 7P These concepts sometimes represent marketing mix interchangeably as they are accepted by many researchers and marketers

Price: This is about how to set the suitable price for the product Price should not be

too high so that customers can afford buying, but not too low so that the company can have profit (Kotler and Armstrong, 2004, p.107)

Moreover, Kotler et al (2008, 663) presents seven different strategies for adjusting the price; discount and allowance pricing, segmented pricing, psychological pricing, promotional pricing, geographical pricing, dynamic pricing and international pricing For example from discount and allowance pricing could mention a quantity dis-count

and seasonal discount which are important also for sunmall.vn Quantity discount means lower prices for those who buy big amounts of products or services Seasonal

discounts are given when demand is low for certain products For example in spring, winter clothes are often sold on sale, because they are not needed anymore (Kotler

et al., 2008, 663.) Kotler et al (2008, 664) divides segmented pricing into four different categories Customer-segment pricing means different prices for different customers For example entrance fee to an amusing park is cheaper for children than for adults Product-form pricing is that different forms of certain product have different prices For example fresh pineapple and canned pineapple are basically the same product but in different forms and also priced differently Time pricing is usual form for example for electric companies who offer electricity at night with lower price

According to Kotler et al (2008, 665) pricing is also a psychological issue Many people measures with price the quality of the product By price is meant the amount that customer pays for the product or service When thinking of pricing, especially in e-commerce, there are many things which need to be considered carefully For example in Sunmall website it is not enough that they get a little bit more money from the customer than what Sunmall website have to pay for example for a employees, advertisement and products of suppliers Need to be noticed that there are two kinds

of costs; variable costs and fixed costs (Kotler et al 2008, 642)

Trang 18

Promotional pricing is used in a short term way, when companies want to increase their sales (Kotler et al 2008, 666) Stores can for example lower the price of cheese temporarily which gets people to come to the store, and may be at the same time, they buy something else Geographical pricing have to be thought of when doing business throughout the country or the world For example transport costs effects on the decision whether the price is same for European companies and American companies when the distance is bigger In dynamic pricing the customer’s situation is individually thought and the price is set based on that (Kotler et al 2008, 668) In international pricing is effected the whole situation in one certain country Pricing needs to be adjusted for example by the regulations and laws of the country and also costs need to be thought which also vary a lot from country to another (Kotler et al

2008, 671.)

Products: Which means combined "goods and services” that companies give to key

markets The decision about the company's products must be designed with

appropriate features that satisfy customers (Kotler and Armstrong, 2004, p.107) Services have mostly three common basic features (Grénroos, 2000, 47) Firstly, services are a process and these processes consist of functions or a series of functions, not from things Secondly, services are produced and consumed at the same time Third issue is that the customer takes part into the process of producing the service Grénroos (2000, 49) presents two ways, how services are classified Firstly services can be divided into groups which underline humanity and technology, secondly services which are provided from time to time or constantly create the second group Customers are not buying only the certain product but there comes so much more with it Product can be divided into three different levels which each of them in- creases the value of the product (Kotler et al 2008, 500-501) The first level is core product, the real product that customer is buying The next level is an actual product which includes all the supplementary material; for example packaging, brand, quality Third level is augmented product which includes for example delivery, credit,

Page 16

Trang 19

warranties and aftersales In Sunmall website all these aspects are also considered quite precisely and after sales play an important role when creating of Sunmall a

strong brand which tells about quality

Distribution: This includes activities aimed at making the company's products to key consumers Decision on distribution of the company includes the channels, coverage, location, inventory, shipping, warehousing (Kotler and Armstrong, 2004 p107) Nowadays the location is not necessarily so vital anymore for every company, it depends a type of the company Internet has made everything easier and access to other side of the globe can be even easier via Internet than visiting the store in down

town Although place is an important aspect to think in business but more vital is the

availability and accessibility (Krishna, Gopala Raghavan & Reddy, 2010, 85) Products need to be available for the customers and accessibility needs to be simple Selling can be direct selling at the place via sales people but it can also happen for example via catalogues, telephone or trade fairs and many uses combination of

different selling tactics (Tracy, 2004) The most important aspect is to find out the

most effective way to do business, the key is to find out what sells and how to sell it

to the customers (Krishna et al., 2010, 85)

Promotions: This means that the activities to convey the beauty of the product and convince buyers to buy its key The promotion activity in the mixture as advertising, sales, promotions, (Kotler and Armstrong, 2004, p.107)

Krishna et al (2010, 79) defines promotion as a tool which is used to build the company’s image and difference from competitors Buyer’s behavior is one aspect which need to be taken considered of There is a rule which says:

“Whatever method of marketing and sales you're using today will, sooner or later, stop working Sometimes it will stop working for rea-sons you know, and sometimes

it will be for reasons you do not know In either case, your methods of marketing and sales will eventually stop working, and you'll have to develop new sales, marketing and advertising approaches, offerings, and strategies (Tracy, 2004.)”

Trang 20

Promotion is used because of informing, reminding and persuading (Krishna et al.,

2010, 80) Promotion means selling the product so promotion is everything that companies do in order to attract their customers and get their products sold Companies need to inform their customers for example about their new product, remind about the great advantage what there exists if they buy it from them and of course persuade in order to close the deal and either create a new customer relationship or strengthen an old one

Krishna et al (2010, 81) presents a promotional tool which every company should use when promoting their company Promotional tool is a promotional-mix where

should take into consideration for example aspects from advertising, personal selling

and public relations In working on sales, there is no one certain right answers

Markets live all the time and markets are huge which includes millions of different

opinions Companies need to develop among them or they are not going to manage

It is brutal game but customers determine the way

People: Including those related to services either directly or indirectly This mainly relates to staff (contact center employees, representatives, and management staff) (Bernard et al 1981)

Every company has their own alignments and policies concerning of their actions When thinking of personnel, this is a tough question for example what the right capacity is, needed qualification of the employees, is there need for further education, what is the right way to choose the personnel and of course how is all this going to

be managed (Dienstleistungsmarketing, 2012) People section is important part for every company People section forms of personnel and of customers It is crucial for

a company to have a motivated and qualified staff because they are the people who basically can increase or decrease the selling of the company If customers don’t like the person who they are doing business with and the person gives an incompetent feeling for the customer, it effects directly to the results (Krishna et al, 2010, 86.)

Page 18

Trang 21

Companies should have on their service only people, who have right training for the work and who knows about the products, which they are doing business with If this

is not the case, a wise employer provides the right training for employees so people are able to do their work properly and customers will get professional image of the company, good service and they remain satisfied Especially people who works in customer service should have good communication skills and to be suitable for customer service If customer works with the company for the very first time and the first impression is poor because of poor customer service, has it clear reflections to the business According to Krishna et al (2010, 87) by providing a good training for

all employees and taking into service only people who have the right attitude towards

the job and managing the company as an inspiring style, provides good results Quality is one important aspect which determines whether the customers choose the company to do business with or not According to Grénroos (2000, 63) quality is determined by the customers thus quality is everything what customers think it is Process: This relates to the operational aspects of the service such as: receive and process orders, timing and sequence of activities leading to the experience of

consumers of services Create a process of effective services is essential for the

success of a service company (Bernard et al 1981)

In addition, process means all the systems which are used when company delivers the

service for their customers Process is all the steps that need to be taken from thinking

of buying to the final purchasing decision The company needs to convince the customer that their products and services are high-qualified and they are trustworthy When service and even every minor technical aspect works, it keeps customers happy and they become involvement with the company and their products (Kumar, 2010, 49-50.) When PGFV company gets a question about a online shopping they are offering for, a customer expects the answer the sooner the better

Gilbert (2003, 115) presents a figure from Boom and Bitner from 1981 about the marketing mix for services There process-section has explained to include all the

Trang 22

policies and procedures that company follows, the function of all the mechanics and

in nowadays electronics, employees’ ability to make circumspect decisions, how customer take part into the whole process, is the process rightly directed to the

customer and all the steps that need to be taken in the whole process of the company

Physical Evidence: is the entire environment, in which, the service is presented and provide to consumers It includes tangible value which creates awareness of services and company service providers (Bernard et al 1981) Three sizes physical environment represents the relationship between the service and the environment: Environmental conditions such as temperature, sound, smell, space and functionality

such as maps, equipment, decorations, signs, symbols and artifacts such as signatures,

personal contacts (Bernard et al 1981)

Moreover, physical evidence is everything that can be seen or touched around the company The quality of catalogues can effect on decision whether to buy something from one company or from the other Everything near the company is under supervision from the point of view of customers; furniture, the outfit of the premises, whether customer can get a cup of coffee during the visit or not, everything can effect

to the customer (Krishna et al., 2010)

Krishna et al (2010, 88) divides physical evidence into two categories; peripheral evidence and essential or dominant evidence By peripheral is meant almost insignificant issues for the company which can mean a lot for the customer and give

a certain image for the company Krishna, et al 2010 used as an example a movie ticket For the cinema it is only a system to supervise the customers so everyone who wants to see a film has to buy a ticket but for a customer it can be more For example Finnkino in Finland prints on the other side of the ticket usually a discount for example to the nearest pizzeria That way the ticket is not only a way to see the movie

for customer but he or she can also get other types of benefits of it which can improve

company’s image Essential evidences are those which give a direct image about the quality of the company, for example premises in the airplane

2.2.3 7P Marketing role and its importance in online shopping

The increase in the number of internet users have made online marketing's role is growing The spread brand and promote your products have become easier than traditional methods Shopping habits of users are also changed By internet marketing

tools, modern businesses can freely adjust as well as control the behavior of

consumers easily

By using free online tools like fan page, website, email, social networks People can cut the cost and time to reach potential customers Also based on the available

tools can now calculate and evaluate performance and customer behavior In addition,

it help business approaches to the target customer, retrench geographical gap, and keep away from intermediate cost, takes time

Based on the online marketing tools, businesses have high competitive advantage Spread and promote brand products is now easier via the Internet Moreover, they also create the popularity for products and services of enterprises Businesses can approach customers around the world through a mouse-click that traditional marketing cannot do

Can access, purchase, exchange of information anytime in unlimited time

Payments are easy and diversify

Moreover, internet is considered the good choice for providing information The huge amount of information to be uploaded, millions of access per day so that the display

of information on the internet is essential

If more than 10 years ago that we do every morning such as: read the newspapers and listen to the radio, but now those things is done through mainly Internet The number

of people watching TV, listening to the radio, read newspapers are declining sharply due to the user's network access more quickly and be more active People use the internet daily to find information online, shopping, or even learn about a company

they want to cooperate
