- Test the relationship between demographic variables and consumer behavior for Mobile Marketing activities
The analysis method used is the Chi-square test (χ2), with statistical hypotheses H0 and H1 and significance level α = 0.05. In case the P index (p-value) or Sig. index in SPSS has a value less than or equal to the significance level α, the hypothesis H0 is rejected and vice versa. With this testing procedure, the study can evaluate the difference in behavioral trends between demographic groups.
CHAPTER 4
RESEARCH RESULTS
During two months, 1,100 survey questionnaires were distributed to mobile phone users in the inner city of Hanoi using various methods such as direct interviews, sending via email or using questionnaires designed on the Internet. At the end of the survey, after checking and eliminating erroneous questionnaires, the study collected 858 complete questionnaires, equivalent to a rate of about 78%. In addition, the research subjects of the thesis are only people who are using mobile phones, so people who do not use mobile phones are not within the scope of the thesis, therefore, the questionnaires with the option of not using mobile phones were excluded from the scope of analysis. The number of suitable survey questionnaires included in the statistical analysis was 835.
4.1 Demographic characteristics of the sample
The structure of the survey sample is divided and statistically analyzed according to criteria such as gender, age, occupation, education level and personal income. (Detailed statistical table in Appendix 6)
- Gender structure: Of the 835 completed questionnaires, 49.8% of respondents were male, equivalent to 416 people, and 50.2% were female, equivalent to 419 people. The survey results of the study are completely consistent with the gender ratio in the population structure of Vietnam in general and Hanoi in particular (Male/Female: 49/51).
- Age structure: 36.6% of respondents are <23 years old, equivalent to 306 people. People from 23-34 years old
accounting for the highest proportion: 44.8% equivalent to 374 people, people aged 35-45 and >45 are 70 and 85 people equivalent to 8.4% and 10.2% respectively. Looking at the results of this survey, we can see that the young people - youth account for a large proportion of the total number of people participating in the survey. Meanwhile, the middle-aged people including two age groups of 35 - 45 and >45 have a low rate of participation in the survey. This is completely consistent with the reality when Mobile Marketing is identified as a Marketing service aimed at young people (people under 35 years old).
- Structure by educational level: among 835 valid responses, 541 respondents had university degrees, accounting for the highest proportion of ~ 75%, 102 had secondary school degrees, ~ 13.1%, and 93 had post-graduate degrees, ~ 11.9%.
- Occupational structure: office workers and civil servants are the group with the highest rate of participation with 39.4%, followed by students with 36.6%. Self-employed people account for 12%, retired housewives are 7.8% and other occupational groups account for 4.2%. The survey results show that the student group has the same rate as the group aged <23 at 36.6%. This shows the accuracy of the survey data. In addition, the survey results distributed by occupational criteria have a rate almost similar to the sample division rate in chapter 3. Therefore, it can be concluded that the survey data is suitable for use in analysis activities.
- Income structure: the group with income from 3 to 5 million has the highest rate with 39% of the total number of respondents. This is consistent with the income structure of Hanoi people and corresponds to the average income of the group of civil servants and office workers. Those
People with no income account for 23%, income under 3 million VND accounts for 13% and income over 5 million VND accounts for 25%.
4.2 Mobile phone usage in Hanoi inner city area
According to the survey results, most respondents said they had used the phone for more than 1 year, specifically: 68.4% used mobile phones from 4 to 10 years, 23.2% used from 1 to 3 years, 7.8% used for more than 10 years. Those who used mobile phones for less than 1 year accounted for only a very small proportion of ~ 0.6%. (Table 4.1)

The survey indexes on the time of using mobile phones of consumers in the inner city of Hanoi are very impressive for a developing country like Vietnam and also prove that Vietnamese consumers have a lot of experience using this high-tech device. Moreover, with the majority of consumers surveyed having a relatively long time of use (4-10 years), it partly proves that mobile phones have become an important and essential item in people's daily lives.
When asked about the mobile phone network they are using, 31% of respondents said they are using the network of Vietel company, 29% use the network of
of Mobifone company, 27% use Vinaphone company's network and 13% use networks of other providers such as E-VN telecom, S-fone, Beeline, Vietnammobile. (Figure 4.1).
Figure 4.1: Mobile phone network in use
Compared with the announced market share of mobile telecommunications service providers in Vietnam (Vietel: 36%, Mobifone: 29%, Vinaphone: 28%, the remaining networks: 7%), we see that the survey results do not have many differences. However, the statistics show that there is a difference in the market share of other networks because the Hanoi market is one of the two main markets of small networks, so their market share in this area will certainly be higher than that of the whole country.
According to a report by NielsenMobile (2009) [8], the number of prepaid mobile phone subscribers in Hanoi accounts for 95% of the total number of subscribers, however, the results of this survey show that the percentage of prepaid subscribers has decreased by more than 20%, only at 70.8%. On the contrary, the number of postpaid subscribers tends to increase from 5% in 2009 to 19.2%. Those who are simultaneously using both types of subscriptions account for 10%. (Table 4.2).

The above figures show the change in the psychology and consumption habits of Vietnamese consumers towards mobile telecommunications services, when the use of prepaid subscriptions and junk SIMs is replaced by the use of two types of subscriptions for different purposes and needs or switching to postpaid subscriptions to enjoy better customer care services.
In addition, the majority of respondents have an average spending level for mobile phone services from 100 to 300 thousand VND (406 ~ 48.6% of total respondents). The high spending level (> 500 thousand VND) is the spending level with the lowest number of people with only 8.4%, on the contrary, the low spending level (under 100 thousand VND) accounts for the second highest proportion among the groups of respondents with 25.4%. People with low spending levels mainly fall into the group of students and retirees/housewives - those who have little need to use or mainly use promotional SIM cards. (Table 4.3).

The statistics in Table 4.3 are similar to the percentages in the NielsenMobile survey results (2009) with 73% of mobile phone users having medium spending levels and only 13% having high spending levels.
The survey results also showed that up to 31% ~ nearly one-third of respondents said they sent more than 10 SMS messages/day, meaning that on average they sent 1 SMS message for every working hour. Those with an average SMS message volume (from 3 to 10 messages/day) accounted for 51.1% and those with a low SMS message volume (less than 3 messages/day) accounted for 17%. (Table 4.4)

Similar to sending messages, those with an average message receiving rate (from 3-10 messages/day) accounted for the highest percentage of ~ 55%, followed by those with a high number of messages (over 10 messages/day) ~ 24% and those with a low number of messages received daily (under 3 messages/day) remained at the bottom with 21%.

When comparing the data of the two result tables 4.4 and 4.5, we can see the reasonableness between the ratio of the number of messages sent and the number of messages received daily by the interview participants.
4.3 Current status of SMS advertising and Mobile Marketing
According to the interview results, in the 3 months from the time of the survey and before, 94% of respondents, equivalent to 785 people, said they received advertising messages, while only a very small percentage of 6% (only 50 people) did not receive advertising messages (Table 4.6).

The results of Table 4.6 show that consumers in the inner city of Hanoi are very familiar with advertising messages. This result is also the basis for assessing the knowledge, experience and understanding of the respondents in the interview. This is also one of the important factors determining the accuracy of the survey results.
In addition, most respondents said they had received promotional messages, but only 24% of them had ever taken the action of registering to receive promotional messages, while 76% of the remaining respondents did not register to receive promotional messages but still received promotional messages every day. This is the first sign indicating the weaknesses and shortcomings of lax management of this activity in Vietnam. (Table 4.7)

“The Balanced Scorecard (BSC) is a strategic planning and management system widely used in non-profit, government, industrial and business organizations worldwide. Its purpose is to align business activities with the organization's vision and strategy, improve internal and external communications, and monitor organizational performance against strategic goals. It gives managers and senior officials in organizations a more balanced view of the organization's overall performance.” [1]
The balanced scorecard includes the following elements:
-Perspectives: includes many groups of 4-5 goals
- Themes: are groups that include many strategic goals
- Objectives: are important factors in the organization's strategy.
- Measures: are tools to evaluate the organization's performance with goals to set
- Initiatives: are projects proposed to achieve the organization's goals.
The Balanced Scorecard, first theorized by Robert S. Kaplan and David P. Norton in “Translating the Strategy into Action – The Balanced Scorecard, 1996”, (See Appendix I) is built on four main perspectives: the financial perspective, the customer perspective, the internal business process perspective, and finally the research and innovation perspective. (See Figure 1). The term Balanced Scorecard can be divided into two parts: (1) Scorecard is the measurement, evaluation and management of activities and (2) Balanced is the balance between financial and
non-financial, external factors and internal components of the company, between short-term and long-term goals.
Figure 1: Four perspectives of the Balanced Scorecard [17]

While financial performance measures are very clear about what happened in the past, they are not well suited to the emphasis on how the organization creates real value today - that is, intangible assets such as knowledge, networks of relationships, etc. Therefore, financial measures are considered "lagging indicators". They are the result of a series of actions that have been taken in the past. The BSC complements these "lagging indicators" with future economic performance directions, also known as "leading indicators". But these performance measures (including both lagging and leading indicators) come from the organization's strategy. All measures in the BSC are understood as clarifying the organization's strategy.
Many organizations have attempted to communicate visions and strategies, but often failed to link employee actions to the strategic direction of the organization. The BSC allows organizations to clarify their visions and strategies by providing a new framework. This framework tells the whole story of the organization's strategy through the objectives and measures that have been chosen. Instead of focusing on financial control, the BSC uses measures as a new language to describe the key elements to achieving strategy. How the measures are used is critical to achieving strategy.
strategy. Measurable objectives are essential to translating strategy into reality. The BSC retains financial measures, but adds three other very clear perspectives: Customers, internal processes, and learning and innovation.
Financial Perspective : Financial measures are a very important element of the BSC, especially in today's profit-driven world. They show whether the strategy is being implemented to achieve the bottom line. Businesses can focus all their efforts and capabilities on improving customer satisfaction, quality, on-time delivery, or a host of other issues, but if they don't show a positive impact on the organization's financial metrics, all that effort is worth less. Typically, management is concerned with traditional metrics such as profits, revenue growth, and other economic values.
Customer Perspective: When choosing customer perspective metrics, organizations must answer two important questions: Who are our target customers, and what is the value we are delivering to them? These may sound simple, but they pose a significant challenge for organizations. Most organizations will claim that they have a target customer, and their activities demonstrate that their strategy is “Everything for everyone.” The reality is that a lack of focus reduces an organization’s ability to differentiate itself from its competitors. Determining the appropriate value to deliver to customers is also a significant challenge for most organizations. Many organizations will choose one of Treacy and Wiersema’s three rules of market leadership:
- Executive leadership: Organizations pursuing this goal typically focus on low prices, convenience, and generally no frills. Wal-Mart is a classic example of executive leadership.
- Product Leadership: Product leadership companies usually pursue product development that is unique to the company. They always try to bring the best products to the market. Nike can be an example of product leadership in sports goods.
- Customer Intimacy: Doing everything possible to provide solutions to individual customer needs will help a company win the love of customers. These companies often focus on long-term relationships with customers through deep understanding of customer needs. In the retail industry, Nordstrom is a model company for winning the love of customers.
Regardless of which of the three disciplines an organization chooses, the customer perspective today typically uses metrics such as: Customer satisfaction, customer loyalty, market share, and number of new customers.
Internal Business Processes Perspective : In the customer perspective of the balanced scorecard (BSC), we must identify the key processes the organization needs to perform to consistently add value to customers and ultimately shareholders. Each of the disciplines listed above will require the performance of specific internal processes that serve customers. The task of each business in this perspective is to identify those key processes and develop the best possible measures of improvement. In order to satisfy customer needs, organizations can identify new internal processes, rather than focusing their efforts on making minor improvements to the organization's current processes. Product development, manufacturing, production, delivery, and after-sales activities are considered in this perspective.
Learning and innovation perspective : Organizations want to achieve good results in the internal process and customer perspectives. So where do those results come from? Learning and growth measures are actually supports for achieving results in the other perspectives. In essence, these measures are the foundation on which the “house of the Balanced Scorecard” is built. When organizations identify measures and initiatives in the customer and internal process perspectives, they can quickly see the gaps between the current state and the levels needed to achieve the goals in fundamental factors such as employee skills, information systems, etc. The measures that the
Organizations that identify in this aspect will help fill those gaps and ensure sustainable performance in the future.
Employee skills, employee satisfaction, and resource availability can all be included in the learning and growth perspective. The measures we develop in this perspective actually support the measures in the other perspectives of the company’s Balanced Scorecard system. Think of it as the roots of a tree, which feed the trunk (internal processes) and then the branches (customer deliverables) and finally the leaves (financials).
2. The role of the Balanced Scorecard
The Balanced Scorecard helps companies scale the goals of each business unit to a single financial metric. Management can now measure how many customers each business unit generates now and in the future, how to leverage its capabilities, and what investments in people, systems, and processes are needed to improve future performance. The Balanced Scorecard captures the critical value-creating activities that are created by dedicated, skilled individuals in the organization. In addition to looking at short-term financial gains, the Balanced Scorecard also reveals long-term financial value and competitiveness.
The Balanced Scorecard emphasizes that financial and nonfinancial measures must be part of the information system for employees at all levels of the organization. Frontline employees must understand how their actions and decisions lead to the company's financial results, and senior managers must be the drivers of long-term success. The Balanced Scorecard's objectives and measures are derived from a top-down process driven by the mission and strategy of each business unit that actually integrates financial and nonfinancial performance measures. The Balanced Scorecard translates the company's mission and strategy into tangible objectives and measures. These measures represent a balance between external measures for shareholders and internal measures for the company.
and customers, with internal measures for key business processes, innovation, and research and learning. Furthermore, the Balanced Scorecard is a tactical measurement system. Innovative companies are using the Balanced Scorecard as a strategic management system to manage their strategy over the long term (See Figure 2). Here are four key roles of the Balanced Scorecard in implementing management processes in the organization:
- Clarify and understand the company's vision and strategy.
- Communicate and connect strategic goals with metrics
- Plan, set goals and align strategic initiatives
- Reinforce strategic feedback and learning.
Figure 2: Balanced scorecard in translating strategy into objectives [13]

2.1. Clarify and understand the company's vision and strategy
This process begins with the senior management team working together to translate each business unit’s strategy into clear strategic objectives. To achieve financial objectives, the team needs to consider whether to focus on revenue and market growth, profitability, or cash flow. However, especially on the customer side, the management team needs to be clear about which customers and market segments will determine the competition. For example, in one financial institution, 25 senior managers agreed that the company’s strategy was to provide the best service to its target customers. However, in setting these objectives,
Each manager had a different view of what good service looked like and who the target customers were. The process of developing the scorecard metrics resulted in a consensus among the 25 managers on the most desirable customer segments, and the products and services the bank should offer to reach those target segments.
After setting customer and financial objectives, an organization needs to identify those objectives and measures for its internal business processes. This identification represents one of the key improvements and benefits of the Balanced Scorecard approach. Traditional performance measurement systems, even those that use nonfinancial metrics, focus on improving costs, quality, and the closed-loop nature of the production process. The Balanced Scorecard focuses on the processes that are most important to achieving breakthroughs for shareholders and customers.
The final link to learning and growth is the rationale for investing heavily in employee retraining, information systems and technology, and improving organizational processes. Such investments in people, systems, and processes will create major shifts in internal business processes, for customers, and even for shareholders.
The process of developing the Balanced Scorecard clarifies strategic objectives and identifies the key elements of those strategic objectives, while also creating a common model for the entire enterprise so that each individual can contribute to that common development. The goal of the scorecard is to become a shared responsibility of the senior management team, which creates focus and teamwork among all senior leaders, regardless of their role in the HR or functional areas.
2.2. Communicate and connect strategic goals with metrics
The strategic goals and measures in the Balanced Scorecard are communicated throughout the organization through articles, newsletters, company videos, and even personal computer networks. This helps employees see the important goals of the company and what needs to be done well if they are to be successful.
want the organization’s strategy to succeed. Some organizations try to translate high-level strategic measures from each business unit’s scorecard into specific measures for operational levels. For example, the on-time delivery goal on the scorecard is specified as reducing the operating time of a specific process. In this way, internal improvement efforts become synonymous with organizational success factors. When all employees understand the high-level goals and measures, they can set specific goals to achieve the overall strategy of their business unit.
The balanced scorecard also provides a platform for communicating strategy to corporate and board management and helping them deliver on those mandates. The scorecard encourages a dialogue between business units and corporate and board leaders, not just about short-term financial issues, but also about how to execute the strategy to make a leap forward.
Thus, at the end of the communication and engagement process, everyone in the organization will understand the long-term goals of each business unit, as well as the strategy to achieve those goals. Individuals involved in internal activities will contribute to achieving the business unit goals. And all organizational efforts and initiatives will be transformed to match the necessary change process.
2.3. Plan, set goals and transform strategic efforts
The balanced scorecard has its greatest impact when it is deployed to effect organizational change. Senior management sets goals for the scorecard methods, which, if achieved within three to five years, will result in significant changes to the company. These goals represent the performance of each business unit. If the business unit is a public company, achieving the goal will result in a doubling or more of the stock price. Financial goals for the organization include doubling the capital turnover rate or increasing sales by 150% within five years. For an electronics company, the financial goal is to double the growth rate of current customers.

- Test the relationship between demographic variables and consumer behavior for Mobile Marketing activities
The analysis method used is the Chi-square test (χ2), with statistical hypotheses H0 and H1 and significance level α = 0.05. In case the P index (p-value) or Sig. index in SPSS has a value less than or equal to the significance level α, the hypothesis H0 is rejected and vice versa. With this testing procedure, the study can evaluate the difference in behavioral trends between demographic groups.
CHAPTER 4
RESEARCH RESULTS
During two months, 1,100 survey questionnaires were distributed to mobile phone users in the inner city of Hanoi using various methods such as direct interviews, sending via email or using questionnaires designed on the Internet. At the end of the survey, after checking and eliminating erroneous questionnaires, the study collected 858 complete questionnaires, equivalent to a rate of about 78%. In addition, the research subjects of the thesis are only people who are using mobile phones, so people who do not use mobile phones are not within the scope of the thesis, therefore, the questionnaires with the option of not using mobile phones were excluded from the scope of analysis. The number of suitable survey questionnaires included in the statistical analysis was 835.
4.1 Demographic characteristics of the sample
The structure of the survey sample is divided and statistically analyzed according to criteria such as gender, age, occupation, education level and personal income. (Detailed statistical table in Appendix 6)
- Gender structure: Of the 835 completed questionnaires, 49.8% of respondents were male, equivalent to 416 people, and 50.2% were female, equivalent to 419 people. The survey results of the study are completely consistent with the gender ratio in the population structure of Vietnam in general and Hanoi in particular (Male/Female: 49/51).
- Age structure: 36.6% of respondents are <23 years old, equivalent to 306 people. People from 23-34 years old
accounting for the highest proportion: 44.8% equivalent to 374 people, people aged 35-45 and >45 are 70 and 85 people equivalent to 8.4% and 10.2% respectively. Looking at the results of this survey, we can see that the young people - youth account for a large proportion of the total number of people participating in the survey. Meanwhile, the middle-aged people including two age groups of 35 - 45 and >45 have a low rate of participation in the survey. This is completely consistent with the reality when Mobile Marketing is identified as a Marketing service aimed at young people (people under 35 years old).
- Structure by educational level: among 835 valid responses, 541 respondents had university degrees, accounting for the highest proportion of ~ 75%, 102 had secondary school degrees, ~ 13.1%, and 93 had post-graduate degrees, ~ 11.9%.
- Occupational structure: office workers and civil servants are the group with the highest rate of participation with 39.4%, followed by students with 36.6%. Self-employed people account for 12%, retired housewives are 7.8% and other occupational groups account for 4.2%. The survey results show that the student group has the same rate as the group aged <23 at 36.6%. This shows the accuracy of the survey data. In addition, the survey results distributed by occupational criteria have a rate almost similar to the sample division rate in chapter 3. Therefore, it can be concluded that the survey data is suitable for use in analysis activities.
- Income structure: the group with income from 3 to 5 million has the highest rate with 39% of the total number of respondents. This is consistent with the income structure of Hanoi people and corresponds to the average income of the group of civil servants and office workers. Those
People with no income account for 23%, income under 3 million VND accounts for 13% and income over 5 million VND accounts for 25%.
4.2 Mobile phone usage in Hanoi inner city area
According to the survey results, most respondents said they had used the phone for more than 1 year, specifically: 68.4% used mobile phones from 4 to 10 years, 23.2% used from 1 to 3 years, 7.8% used for more than 10 years. Those who used mobile phones for less than 1 year accounted for only a very small proportion of ~ 0.6%. (Table 4.1)

The survey indexes on the time of using mobile phones of consumers in the inner city of Hanoi are very impressive for a developing country like Vietnam and also prove that Vietnamese consumers have a lot of experience using this high-tech device. Moreover, with the majority of consumers surveyed having a relatively long time of use (4-10 years), it partly proves that mobile phones have become an important and essential item in peoples daily lives.
When asked about the mobile phone network they are using, 31% of respondents said they are using the network of Vietel company, 29% use the network of
of Mobifone company, 27% use Vinaphone companys network and 13% use networks of other providers such as E-VN telecom, S-fone, Beeline, Vietnammobile. (Figure 4.1).
Figure 4.1: Mobile phone network in use
Compared with the announced market share of mobile telecommunications service providers in Vietnam (Vietel: 36%, Mobifone: 29%, Vinaphone: 28%, the remaining networks: 7%), we see that the survey results do not have many differences. However, the statistics show that there is a difference in the market share of other networks because the Hanoi market is one of the two main markets of small networks, so their market share in this area will certainly be higher than that of the whole country.
According to a report by NielsenMobile (2009) [8], the number of prepaid mobile phone subscribers in Hanoi accounts for 95% of the total number of subscribers, however, the results of this survey show that the percentage of prepaid subscribers has decreased by more than 20%, only at 70.8%. On the contrary, the number of postpaid subscribers tends to increase from 5% in 2009 to 19.2%. Those who are simultaneously using both types of subscriptions account for 10%. (Table 4.2).

The above figures show the change in the psychology and consumption habits of Vietnamese consumers towards mobile telecommunications services, when the use of prepaid subscriptions and junk SIMs is replaced by the use of two types of subscriptions for different purposes and needs or switching to postpaid subscriptions to enjoy better customer care services.
In addition, the majority of respondents have an average spending level for mobile phone services from 100 to 300 thousand VND (406 ~ 48.6% of total respondents). The high spending level (> 500 thousand VND) is the spending level with the lowest number of people with only 8.4%, on the contrary, the low spending level (under 100 thousand VND) accounts for the second highest proportion among the groups of respondents with 25.4%. People with low spending levels mainly fall into the group of students and retirees/housewives - those who have little need to use or mainly use promotional SIM cards. (Table 4.3).

The statistics in Table 4.3 are similar to the percentages in the NielsenMobile survey results (2009) with 73% of mobile phone users having medium spending levels and only 13% having high spending levels.
The survey results also showed that up to 31% ~ nearly one-third of respondents said they sent more than 10 SMS messages/day, meaning that on average they sent 1 SMS message for every working hour. Those with an average SMS message volume (from 3 to 10 messages/day) accounted for 51.1% and those with a low SMS message volume (less than 3 messages/day) accounted for 17%. (Table 4.4)

Similar to sending messages, those with an average message receiving rate (from 3-10 messages/day) accounted for the highest percentage of ~ 55%, followed by those with a high number of messages (over 10 messages/day) ~ 24% and those with a low number of messages received daily (under 3 messages/day) remained at the bottom with 21%.

When comparing the data of the two result tables 4.4 and 4.5, we can see the reasonableness between the ratio of the number of messages sent and the number of messages received daily by the interview participants.
4.3 Current status of SMS advertising and Mobile Marketing
According to the interview results, in the 3 months from the time of the survey and before, 94% of respondents, equivalent to 785 people, said they received advertising messages, while only a very small percentage of 6% (only 50 people) did not receive advertising messages (Table 4.6).

The results of Table 4.6 show that consumers in the inner city of Hanoi are very familiar with advertising messages. This result is also the basis for assessing the knowledge, experience and understanding of the respondents in the interview. This is also one of the important factors determining the accuracy of the survey results.
In addition, most respondents said they had received promotional messages, but only 24% of them had ever taken the action of registering to receive promotional messages, while 76% of the remaining respondents did not register to receive promotional messages but still received promotional messages every day. This is the first sign indicating the weaknesses and shortcomings of lax management of this activity in Vietnam. (Table 4.7)
