Trang 7ABSTRACT
The purposes of this study were to determine if there is a relationship
between job satisfaction and organizational culture at Vietnam Association of
Business Culture Development (VNABCD), and to measure those relationships
if they were present Understanding how these areas relate may enhance strategic
planning and personnel decisions for leaders within organizations The
population of this study was the 192 full-time employees from 9 companieswhich are members of Vietnam Association of Business Culture Development
Participants in the study were asked to complete three test instruments: anEmployee Demographic Survey, Organizational Culture DimensionQuestionnaire developed by Business Research Lab, and the Brief Index ofAffective Job Satisfaction (BIAJS)
The study shows a positive relationship between 2 organizational culture
dimensions (reward and recognition, and balance of work) and job satisfaction.
Trang 8Significance of this study
In today's business environment, organizational culture is used as a
powerful tool that describes many facets of a workplace as well as to quantify the
way a business functions Research has confirmed that organizational culture is
not only able to change, guide and display but also give significant contributions
by influencing the thought, feeling, interacting and performance in the
organization The importance of culture is enhanced through its impact on employee morale and work attitudes such as job satisfaction
Organizational culture and job satisfaction have received significant
attention in studies of the work place This is due to the general recognition that
these variables can be the major determinants of organizational performance and
effectiveness Some studies have reported strong correlations of organizational culture and job satisfaction with turnover When employees are dissatisfied at work, they are less committed and will look for other opportunities to quit If
opportunities are unavailable, they may emotionally or mentally “withdraw”
from the organization Thus, job satisfaction is important attitude in assessing
employees’ intention to quit and the overall contribution of the employee to the
organization
Furthermore, recent researches about organizational culture were firmly agreed that gaining an understanding of how organizational culture affects job
satisfaction within the organizational framework may provide the competitive
advantage for organizational success
Purpose of the study
The purposes of this study are to determine if (a) there is a relationship
between job satisfaction and organizational culture at VNABCD (b) to measurethose relationships
Trang 9Scope of the study
Space: Various companies which are members of Vietnam Association ofBusiness Culture Development
Time: from 2TM, March to 17", April
Trang 10CHAPTER 1: LITERATURE REVIEW
1.1 Introduction
Job satisfaction and organizational culture have been interest topic ofsocial science, business, and education researchers for long time They tried toanalyze and evaluate the relation between the individual employee’s jobsatisfaction and organizational culture Most of studies about this topic have been
conducted in the service industry However, researchers always seeking way to
apply in other industries
1.2 An Overview of Job Satisfaction
1.2.1 Concept of job satisfaction
Job satisfaction is a topic that often seems to be self-explanatory If one is
satisfied with his or her current employment situation, then he or she must have
an acceptable level of “job satisfaction” In some instances, this may be true
However, job satisfaction is more complex and involves considerably moreanalvsis than one may imagine
According to Morgan, McDonagh, & Ryan-Morgan, there is two types of
job satisfaction The first type is global job satisfaction concerning about overall
level of satisfaction Global job satisfaction is determined by asking individuals
on the factors and motivational forces that led to their view of job satisfaction
This type of job satisfaction is quite simplistic in nature because it can be
measured by some short questions It may be said that understanding job
satis'action goes much deeper than asking a few questions to the individualempoyee However, global job satisfaction is considered a good _ initialinvestigation into the level of job satisfaction
The second type of job satisfaction called facet job satisfaction may beconsidered the deeper global job satisfaction This type sees level of job
satis‘action of an individual in terms of specific components of his or her job
postion For example, a sale person that finds great pleasure in having personal
Trang 11contact with clients but despises the paperwork generated from his or herresponsibilities Satisfaction is derived from one facet of his or her work whiledispleasure may result from another facet Employers and managers may noticethat different aspects of an employee’s work experience will result in differing
levels of job satisfaction Measuring facet job satisfaction is important and is achieved by performing regular evaluations on the intrinsic and extrinsic factors that affect employee satisfaction (Morgan, McDonagh, & Ryan-Morgan, 1995).
Morgan, McDonagh, and Ryan-Morgan identified several key intrinsic
and extrinsic factors that could influence level of employees’ satisfaction The
intrinsic factors are related to the employee’s position such as the nature of work,
specialization of tasks Extrinsic factors that may shape job satisfaction are thosecomponents that appear outside the actual performance of work responsibilities.Salary, the work environment, and the organizational culture are generallyrecognized as extrinsic factors (Morgan, McDonagh, & Ryan-Morgan, 1995)
Ganzach went different way by considering demographic characteristics
as a factor influencing job satisfaction He suggested that an employee’s level of
education might influence job satisfaction Those who have higher levels of
education were more likely to find employment opportunities that high level ofprofessional and emotional reward These positions may lead to an indirect
increase in the level of job satisfaction of the individual Conversely, thoseindividuals with higher levels of education may also find decreasing levels of jobsatisfaction if the reward is not worth of their education It can be said those with
higher levels of education may have higher levels of reward expectation frompositions Job satisfaction may decrease when the individual finds that the salary,benefits, or other rewards associated with the position are below his or her
expectations (Ganzach 2003)
Greenleaf (1977) developed a philosophy of servant leadership When
servant leadership are present within an organization, the levels of employee job
satisfaction in that organization may improve due to the culture present.Greenleaf described servant leadership in terms of an institution transforming its
Trang 12culture into one that serves all vital components of that organization The vitalcomponents may range from external customers to the employees that comprisethe organization.
In conclusion, job satisfaction is viewed in multiple facets ranging fromoverall to separate components However, during this study, the researcher would
like to use global job satisfaction according to Morgan, McDonagh, &
Ryan-Morgan From now on, job satisfaction will be understood as global job
satisfaction or overall job satisfaction.
1.2.2 Measurements of job satisfaction
Measuring job satisfaction is difficult, because it is abstract personalcognition that only exists in the mind of individual However, some researchershave tried to develop instruments for measuring job satisfaction Most of theseinstruments are based on quantitative method
Originally Index of Work satisfaction (IWS) was develop in the 1972s(Stamp, 1997 cited in Norbu, 2010) This scale is to measure various components
of job satisfaction It includes six components: |) professional status, 2) taskrequirements, 3) pay, 4) interaction, 5) organizational policies, and 6) autonomy.This scale was developed based on the combination of Maslow’s theory andHerzberg’s theory It consisted of 48 items and ranged on a 7-point Likert scale
Previous studies have reported the Cronbach coefficient alpha in the range of for
the overall scale
Originally the McCloskey/Muller Satisfaction Scale (MMSS) was
developed in the 1974s (McCloskey & Muller, 1990) This scale measures
hospital nurses’ job satisfaction from 8 subscales: 1) extrinsic rewards, 2)
scheduling, 3) the balance of family and work, 4) co-worker, 5) interaction opportunities, 6) professional opportunities, 7) praise and recognition, and 8)
control responsibility This scale was developed based on theories of Maslow and
Burn It consisted of 31 items and ranged on a 5-point Likert scale Previousstudies have reported the Cronbach coefficient alpha of 89 for the overall scale
Trang 13and validity of 556 This scale is well established instrument for measuring jobsatisfaction (Arab, Pourreza, Akbari, Ramesh, & Aghlmand, 2007; Duong,
2003)
The Job Satisfaction Survey (JSS) was developed in 1985s by Spector.
This scale assesses employee attitudes about the job and aspects of job from 9separate facets of the job satisfaction: 1) pay and pay raises, 2) promotional
opportunities, 3) fringe benefits, 4) contingent reward, 5) supervision, 6)
coworker, 7) nature of work, 8) communication within the organization, and 9)operating procedures The scale was summated rating scale format which is the
most popular for job satisfaction scales It consisted of 36 items and ranged on a 6-point Likert scale from I-dissapree strongly to 6-agree strongly It has some of
the items written in negatives direction These items have to be reversing scored
before summing up the score Spector reported coefficient alphas ranging
0.60-0.91 for the overall measure (Spector, 1997) The higher mean score is the higherlevel of job satisfaction Level of job satisfaction is low when the mean score isless than 3.00, moderate when the mean score is 3.00-4.00, high when the mean
score is greater than 4.00 (Spector, 2007).
In 2002, Kinicki, McKee-Ryan and Schriesheim developed JobDescriptive Index (JDI) The JDI is designed to measure five sub-dimensions,
which are satisfaction with work, supervision, coworkers, pay, and promotion(Kinicki et al., 2002) It is a cognitive job satisfaction measure, because it is
based on logical and rational evaluation of the job conditions Cognitive
satisfaction is an appraisal based on comparisons which do not rely on emotional
judgments Instead cognitive satisfaction includes evaluations of conditions,Opportunities, or outcomes (Moorman, 1993) Therefore, cognitive jobsatisfaction measures include questions about the nature of the job, the workingconditions, and the opportunities to satisfy important needs The questions askfor appraisals of the job, not descriptions of the feelings (Moorman, 1993)
The next job satisfaction questionnaire is the Minnesota Satisfaction
Questionnaire (MSQ) This questionnaire consists of a list of job conditions
Trang 14which the respondent is asked to appraise The job conditions include the
working conditions, the pay, the quality of supervision, and the degree of
autonomy and importance in the job (Moorman, 1993) The respondent is not
asked to mention the types of feelings associated with the work or the degree the
work evokes positive or negative emotions As opposed to the cognitive
measures, there are affective measures of job satisfaction Affective satisfaction
is satisfaction that is based on overall positive emotional appraisal of the job.
This satisfaction focuses on whether the job evokes a good mood and positivefeelings and hence affective measures of job satisfaction include questions about
a respondent’s feelings on the job or their mood when working (Moorman,
1993) One example is the Faces Scale, which is one of the first scales used
widely This measure is affectively oriented since it asks for no detailed
appraisals The respondent just reports which facial expressions bestapproximates his/her own while working The face range from very happy to
very sad and clearly reflects an emotional response to work (Moorman, 1993)
The latest way of measuring job satisfaction is the Brief Index of
Affective Job Satisfaction (BIAJS) by Thompson & Phua (2012) The BIAJS
tries to assess the overall job satisfaction by using 5 questions This measurement
show the increase in validity, there is also an increase in comparability in somerecent researches The author of this thesis also choose this measure because of
its validity indicated in earlier studies and its simplicity It is clear thatVietnamese staffs find difficulty in answering vast amount of questions, so shortquestionnaire will work best
1.3 An Overview of Organizational Culture
1.3.1 Concept of Organizational Culture
Organizational culture is a phenomenon that occurs in many different
facets The formal definition of organizational culture stated by Schein (2004)
was as follows: a pattern of shared basic assumptions that was learned by a group
as it solved its problems of external adaptations and internal integration, that has
worked well enough to be considered valid and, therefore, to be taught to new
Trang 15members as the correct way to perceive, think, and feel in relation to thoseproblems Culture is an area that has not benefited from the breadth of researchand discussion job satisfaction and motivation However, organizational culturehas a major influence on satisfaction for individual employees.
Schein (2004) described culture as the “phenomena that are below the
surface, that are powerful in their impact but invisible and to a considerabledegree unconscious” Culture plays an important role of lifeblood for anorganization The personality that an organization treat employees and to externalcustomers can best is viewed through its culture Therefore, as members of theorganization, the culture of the organization they participated in will shape theirfuture experiences elsewhere
Conversely, as new members, their past experiences will play a role inshaping the culture of the organization in the future Sometimes the size of the
organization plays a role in the establishment of its culture It is easier for smallerorganizations to have a unique culture For larger organizations, it is moredifficult to possess one unique culture The organizational culture for largerorganizations may be as a group of smaller subcultures Not only could there bemultiple subcultures, each of these subcultures could range in depth and breadth
The individual learns to function in one or many of the subcultures in order toachieve his or her goals and objectives (Schein, 2004)
Organizational culture can be viewed in three different levels The first level is visible explicitly in the organization and is called artifacts Artifacts
include the majority of an organization’s capital, both human and physical It
contains an overview of the processes and structure of the organization The
artifact level is similar in nature to the symbolic frame of Bolman and Deal in
that it also incorporates rituals, myths, and ceremonies (Schein, 2004; Bolman &
Deal, 1999) The second level of culture incorporates the strategic goals,initiatives, and philosophies of the organization This level is best described as
the espoused beliefs and values level As an organization matures, the strength of
the cultural philosophies and goals become more engrained in the culture Early
Trang 16in the development of organizational culture, these established beliefs may meet
with challenges and resistance If the beliefs are proven to be beneficial, they
become part of the organization As time progresses, the more successful the
belief, the more it can be solidified into the cultural foundation of the
organization (Schein, 2004) The final level of culture is the fundamentalassumptions of the organization These assumptions are a product of the effects
of successful organizational goals and philosophies Ideas or operationalapproaches usually begin with feelings of great opportunity and considerabledoubt As these approaches are continuously utilized and are proven successful,the way they are viewed changes The approaches become second nature and
their performance becomes mundane
A fundamental assumption is achieved when components of theorganization reach the point that a philosophy projects such a feeling of securitythat it no longer serves as a focus of debate (Schein, 2004) Peterson (2002)described culture in terms of how it relates to schools His definition includedcomponents such as ceremonies, rituals, and the overall personal of the school
that is established over time These elements link together in order to create the
predominant culture of an individual school Each school culture has the
potential to be considered either positive or toxic A positive school cultureoccurs when the school shares a vision and purpose All levels of school
employees are committed to continuous improvement and sacrificing personal
achievement for the benefit of the larger purpose Strong relationships existwithin the school and collaboration among employees in encouraged
Organizational culture is truly the representation of the collective
relationships, ceremonies, and rituals present within the organization It isevident that all individuals play an integral role in shaping the direction of the
organizational culture The potential for developing a negative culture is always
possible and the effort required to reverse a negative culture is tremendous Byunderstanding the components and composition of the organizational culture,both leaders and followers will be better prepared to create and enjoy the mostpositive and productive culture possible
Trang 17Culture itself is a product of a group of people living at the same place and
having similar attitudes and behavior People who belong to a certain culture
share similar norms, history, religion, values and artifacts which distinguish themfrom others Therefore, there are numerous national cultures and even more
subcultures, providing certain types of organization and action In modernsocieties, however, culture is considered to be a tangible or intangible
environment in which a group of people live and work together (Gjuraj, 2013) In
organizational analysis, culture describes the influence and interaction among
employees and between employees and the specific institution, organization or
service they work in Hence, contemporary organizations and companies areconsidered to be social groups, and in this way their function should be studiedand promoted
Studying an organization’s specific culture is fundamental to the
description and = analysis of organizational phenomena (Tharp,
2009).Organizational culture has been a subject of investigation for many
decades, as the fact that distinctions between values and expectations of
employees with different cultural backgrounds had always been clear (Tayeb,
1996) Black et al (1992) have come to the conclusion that problems that are
likely to come up during international business activities and working settings are
wrongly attributed to professional incompetence, while they most probably
occur due to the employees inability to perceive other people’s ideas and
attitudes and adapt to foreign strategies Therefore, a fundamental challenge fororganizations is to make their employees re-categorize demographicallydissimilar people as in-group members, in order to increase interaction and
mutual trust and benefit from information diversity (Gruenfeld et al., 1996).
As Hofstede (1991) has noted, the employees’ behavior in their workplace
is influenced by three different cultures: their national, their occupational and
their organizational culture More specifically, an individual’s attitudes and
beliefs toward his/ her occupation are chiefly influenced by his/ her personal
values and ideals, which have been achieved in the frame of family during his/
her earlier development Secondly, a person’s specific views, perceptions and
Trang 18ambitions are formed during school and professional life and belong to the
occupational culture shared among partners.
However, Cooke and Rousseau (1988) viewed organizational culture as
multiple dimensions He suggested 5 dimension including Reward and
Recognition; Individual Initiative; Balance of Work; Ethical Behavior; andCarrier Development Therefore, organizational culture becomes easier to
understand and measure than most of other models Furthermore, the purpose of
the study was to examine the relation between organizational culture and job
satisfaction, so this concept of organizational culture appeared as most suitablemodel for this study
1.3.2 Types of Organizational Culture
Many researchers have tried distinguish different types of organizationalculture in order to describe the format and function of institutions andorganizations
Deal and Kennedy (1982) had suggested four types of organizational
culture, referring to the organization’s strategies and expectations from
employees: 1) The Tough-Guy, Macho culture: employees who belong to thistype of culture usually work under a lot of pressure and are considered to be
eager to take risks In order to fulfill their personal ambitions and theirorganization’s goals 2) The Work Hard/Play Hard culture: in organizations with
this type of culture, the behavior of employees revolves around the needs ofcustomers and is characterized by high speed action in order to get quick results.3) The Bet-Your-Company culture: this type of culture refers mainly to thecharacter of the institution or company, which is likely to make carefully
planned, yet risky, choices and investments 4) The Process culture: the last type
of organizational culture is based on precision, detail and technical perfection,
low risk investments and low levels of anxiety among employees
Another four types of organizational culture have been suggested byXenikou and Furnham (1996), referring to the organization’s goals and decision-
Trang 19making: |) The Openness to change/ innovation culture: this type of culture is
human-oriented and promotes affiliation, achievement, self-actualization, task
support and task innovation 2) The Task-oriented culture: organizations with this
type of culture focus on detail and quality of products or services, while superiors
are characterized by high ambitions and chase success 3) The Bureaucratic culture: this type of culture is rather conservative and employees are characterized by centralized decision making 4) The Competition/Confrontation
culture: organizations with this type of culture are highly competitive, oriented, while superiors chase perfection and achievement
goal-Daft (2001) suggested another four types of organizational culture, based
on environmental requirements: 1) Entrepreneurial Culture: OrganizationalStrategic focus is external so that it acts to meet needs and requirements ofclientele and customers in a dynamic and variable environment It creates
changes and innovation, risk ability, prospect, group working, freedom andautonomy 2) Involvement Culture: It is focused on participation and
involvement of organizational members and environmental expectations which
vary promptly and it creates sense of accountability, ownership and further
commitment to organization in personnel 3) Mission Culture: It takes service to customers in outside environment into consideration It does not need to rapid
changes and instead personnel are accountable for performance up to certain
level 4) Bureaucratic Culture: It is focused internally and adapted to a fixenvironment In such a culture, personnel’s involvement is low but supervisionand control over environment are high Some factors like organizationaldiscipline and rank and position and observance of hierarchy are highly
important in this culture.
Denilson et al (2004) have distinguished four traits types of an
organization’s subcultures: 1) Adaptability: creating change, customer focus,
organizational learning 2) Mission: strategic direction and intent, goals and
objectives, vision 3) Consistency: core values, agreement, coordination andintegration 4) Involvement: empowerment, team orientation, capability
development
Trang 20Another model of organizational culture types has been developed by
Cameron and Quinn (2006) They suggested four types of culture which refer mainly to the relations among employees: 1) The Hierarchical culture: this type
of culture is considered to be well coordinated, characterized by formal rules and policies 2) The Market culture: organizations that adopt this type of culture aim
to be highly competitive, while winning is the “glue” that holds the employees
and the organization together 3) The Clan culture: this type of culture refers to a
friendly and “cozy” working environment, where the working force is perceived
as an extended family and the superiors are perceived as mentors; employees arecharacterized by high job and organization commitment and develop friendlyrelations 4) The Adhocracy type: this type of culture is characterized by
innovation and risk taking, assured by a highly creative and dynamic working
environment Chatman et al (1998) mention two different types-dimensions oforganizational culture: Individualism and Collectivism, which are likely to
influence the process of employees’ social categorization Individualistic
organizational cultures focus on and reward employees’ personalaccomplishments, individual characteristics and abilities This dimension is
rather flexible, as employees are allowed and encouraged to behave in their ownpersonal way Therefore, organizational membership is not salient and
personality traits are appreciated As Markus and Kitayama (1991, p 224) put it,
“individuals maintain their independence from others by attending to the self and
by discovering and expressing their unique inner attributes” Collectivistic
organizational cultures, on the other hand, are characterized by a general
agreement of acceptable actions and behaviors, which assure shared objectives,interchangeable interests and commonalities among employees The mainpriority of collectivistic cultures is independence and cooperation, soorganizational memberships form a basis of social categorization In addition,
employees are likely to accept harsh criticism if they deviate from the culture’snorms (Triandis, 1995), so simply being a member of the organization may be
enough to qualify an employee as an in-group member (Wagner, 1995).However, since collectivistic organizational cultures focus on common targetsand aspirations, employees may perceive their internal disagreements as
Trang 21constructive, rather than threatening for the organization’s success On the
contrary, disagreements and challenges in the frame of individualistic
organizational cultures are likely to be taken more personally and be perceived as
competitive (Axelrod, 1984).
So far it has been made clear that although the concept of organizational
culture is not easily captured and defined, it is an observable and significant
aspect of an organization’s function Since it includes the employee’s shared beliefs, values, behaviors and symbols, it strongly affects individual decisions and group actions Organizational culture could possibly be perceived as a
compass which provides the institution with direction It offers a kind of informal
language for the interpretation of issues and events; it ensures a sense of order
and reduces employees’ uncertainty
Despite the variety of definitions and models suggested for the content
and types of organizational culture, similar descriptions and characteristics can
be found For instance, organizational cultures and its subtypes mainly refer to
the organization’s hierarchy and structure, goals and investment policies In
addition, the working conditions and employees’ behaviors are taken into
consideration while the importance of internal relations is significant.
Additionally, the organization culture of an institution seems to reflect its inner
coherence and completion and external function and adjustment (Schein, 1991).
In general, ii can be said that organizational culture is defined in terms of
employees and superiors, products, processes and leadership’s espoused values
It includes the institution’s experiences, general expectations, internal philosophyand values that hold the working force together and is reflected in its image,external interactions and future plans Therefore, the type of an institution’sorganizationa culture affects its function and general well-being
For this reason, the phenomenon is considered to be multidimensional and
appertains to he fields of psychology, sociology, human resource studies, as well
as business <dministration and management, marketing, product developmentand advertisire (Blake and Lawrence, 1989) Peters and Waterman (1982) have
Trang 22noted that the elements of an organization’s culture decide its possibilities ofsuccess, while the research of Kotter and Heskett (1992) has revealed that thestronger an organization culture is, the more likely it is to last through the changeand replacement of employees Moreover, it must be stated that no organizationalculture type is considered to be better than another The value of each type ismeasured by a specific organization’s well-being, total function and goal
achievement.
For example, the study of Chuah and Wong (2012) showed that in order tocontrol a clan type organizational culture, the organization’s leaders shouldemploy significant resources and authority to influence the building and
leveraging of the clan The leaders “controllers” access a large amount of
resources that are used to guide others for project outcomes, but also promote the
build-up for shared structures, cognition and relationships that smooth the
development of a clan control that strengthen or inhibit clan norms
Other authors, like Rud (2009) focus on collaborative leadership teams,
which are essential for commitment to strategic use of information, regardless theorganizational culture type, in order to reinforce knowledge process Based onHeskett’ state that “organization culture can account for 20-30% of the
differential in corporate performance when compared with ‘culturallyunremarkable” competitors”, Coleman (2013) has distinguished six common
components of successful types of organizational culture: 1) Vision: A specificgoal or mission provides an organization with purpose, which guides employees’decisions and improves relations with customers and suppliers 2) Values: The
values of an institution are the core of its culture They provide guidelines to theemployees, so that communication among colleagues is promoted, professional
standards are held high and the institution’s vision is achieved 3) Practices: Thespecific values of an organization should be followed by equivalent practices,which should be reinforced in review criteria and promotion policies, so that theybecome part of the organization’s everyday life For example, if an institution’s
culture is hierarchical and “flat”, junior team members should be encouraged todissert in discussions without fear or negative repercussions 4) People: The
Trang 23values of an organization should be embraced by both its existing and future
employees and therefore the recruiting policies should focus on people who are
not only talented, but suitable for the organization’s specific culture type 5) Narrative: An organization’s unique history should be identified, shaped and
retold as part of its ongoing culture 6) Place: An integral element of anorganizational culture is its location and working environment, perceived interms of geography, architecture and aesthetic design All those factors are very
likely to influence the employees’ values and behaviors, and thus promote the
organization’s performance and effectiveness Form the entire above, one could
support that the study and improvement of an organization’s culture is a
contributing factor to its success
A few decades back, Hofstede (1986) had pointed out that organizationalculture is fundamental for superior’s perception and control of the organization’s
working force and potential Jackson (2011, p 58) has noted that in modern
societies and technology-based business organizations “culture is becomingincreasingly important given the adoption of groupware applications, enterprise
resource planning systems and other internet based systems by organizations,
which support cross collaboration and require greater user participation at all
levels”
Furthermore, it can be said that organizational culture is a complex
phenomenon, a product of dynamic social process As and Myers (1995, p 52)
had put it: “Cultures are challenged, ever-changing and emergent: they areinvented and reinvented in social life” Consequently, organizational culture hasbeen linked to many occupational phenomena, like human resource management,job commitment, job satisfaction, and -in many cases- occupational stress andburnout This fact has been supported by many researchers, like Farris et al
(1973), who revealed the role of trust in organizational interpersonal
relationships In their research, trust was related to organizational culture and
employees’ job commitment and integration into work groups and organizations
Martins &
Trang 24Terblanche (2003) stated that the two main functions of organizational
culture, internal integration and coordination, have a strong influence on anorganization’s creativity and innovation More specifically, internal integrationdescribes the feeling of belonging and commitment, while coordination refers tothe creation of a competitive ground and development of social glue that holds an
organization together.
1.3.3 Measuring Organizational Culture
Apart from the various types and models that have been suggested for thedescription of organizational culture, quite a big number of instruments for themeasurement of organizational culture have been developed as well In the lastfew decades, both academics and practitioners in management science havefocused on studying possible ways to measure the dimensions of organizationalculture and how such measures relate to the effectiveness and competitiveness of
an organization (Mobley et al., 2005)
Harrison (1975) developed an inventory to address both the existing andthe preferred culture within an organization called the Harrison’s Organizational
Ideology Questionnaire The inventory consists of 15 items assessing the
ideology which has been developed by an organization’s employees in terms of
four dimensions, orientation to power, roles, tasks and individuals Respondentsare asked to rank four statements in each of the 15 items in terms of howrepresentative they are both of the organization and of their own attitudes
Another famous instrument of measuring organizational culture is the
Organizational Culture Inventory (OCI), developed by Cooke and Lafferty(1987) It includes 120 items which assess shared norms and expectations that arelikely to affect the ways of thinking and behavior of group members, resulting 12
styles: humanistic/helpful, affinitive, approval, conventional, dependent,
avoidance, oppositional, power, competitiveness, competence/perfectionalist,
achievement, and self-actualization After analyzing those styles, three factors
arise: people/security culture, satisfaction culture and task/security culture
Trang 25In 1987 as well, Glaser, Zamanou and Hacker carried out the Organizational Culture Survey, designed to address six empirical factors:
teamwork and conflict, climate and morale, information flow, involvement,
supervision, meetings It includes 31 items and the responses were given in a 5 point scale
-In 1990, Hofstede, Neuijen, Ohayv and Sanders carried out a qualitative and quantitative study of 20 cases using Hofstede’s Organizational Culture
Questionnaire The questionnaire included 135 items given in 5-point scales,which were based on three values: need for security, importance of work andneed for authority Within these, there are six factors relating to practice issues:
process vs outcome, employees vs task, parochial vs professional, open vs
closed system, loose vs tight control, normative vs pragmatic
In the mid-1990°s, McKenzie’s Culture Questionnaire (1995) was
developed in the frame of National Health Service It includes 76 items andrespondents tick each statement that they consider to be broadly true of their
organization The questionnaire assesses various factors: employees’
commitment, attitudes to and belief about innovation, attitudes to change, style of
conflict resolution, management style, confidence in leadership, openness and
trust, teamwork and cooperation, action orientation, human resource orientation, organizational direction In 1996, Walker, Symon and Davies published the
Corporate Culture Questionnaire, evaluating four principal domains:
performance, human resources, decision-making and relationships There are two
versions of the Questionnaire, one of 69 and another of 126 items, each given in
a 5-point Likert type scale
Buckingham and Coffman (2000) suggested the Core Employee Opinion
Questionnaire which addressed 13 issues of business units, companies and other
Organizations: overall satisfaction, understanding of expectations, access to
required resources, appropriate use of skills, recognition and praise for achievements, relationship with supervisors, encouragement for self-
development, perceptions of worth, engagement with organizational mission,
Trang 26commitment of all employees, friendship appraisal, opportunities for career
progression.
Cameron and Quinn (2006) created the famous Organizational Culture
Assessment Instrument (OCAI), based on the four culture types mentioned
above The evaluation of a culture is made through those four core values, in a 2
x 2 competing values, Flexibility and discretion opposing Stability and control
and Internal focus and integration versus External focus and differentiation
According to Jones et al (2006), internal versus external focus separates the
organizational improvements driven by mostly internal business processes andpeople caring from the ones caused by external stakeholder wishes Stability
versus flexibility distinguishes between organizations that are more stable and
organizations that promote innovation, personal growth, continuous organizationimprovement and change The competing values cross upon six dimensions:
Dominant characteristics, Organizational leadership, Management of employees,Organizational glue, Strategic emphasis and Criteria of success
Base on dimensional culture theory from Cooke and Rousseau (1988), in
2012, Business Research Lab developed 20-items questionnaire to assess 5
dimensions of organizational culture This measurement shows high level of
reliability in study of Bandana Nayak and Anil Barik (2013) In this research, thismeasurement will be used to determine organizational culture situation of
member of Vietnam Association of Business Culture Development
1.4 Research in Organizational Culture, Job Satisfaction
There has been a large amount of researches conducted in theorganizational culture and job satisfaction The majority of this research has
focused on the service industry in both public and private organizations Most of
researches indicated organizational culture have effect on job satisfaction
Lok and Crawford (1999) evaluated the relationship between
organizational culture, subculture, and commitment Through their research, they
found that organizational subculture had a much stronger relationship to
Trang 27commitment than organizational culture had Furthermore, the researchers found that the level of education, number of years in the particular position, and total number of years of experience did not affect commitment.
Another the study of Lok and Crawford (2004) conducted among managers from Hong Kong and Australia showed that Australian managers
reported higher the innovative and supportive culture measures and on job
satisfaction and organizational commitment When it comes to demographic
characteristics, statistically significant differences were found in the effects of
gender and age on job satisfaction, as they were considered to have a more
positive effect on job satisfaction among employees from Hong Kong
A study conducted by Odom, Boxx and Dnun (2003) at Mckinnon in Taiwan indicates that organizational culture have quite strong effect on job
satisfaction They found that the bureaucratic culture neither improves nordistracts an employee’s commitment and satisfaction They also found that
employee attitudes and behaviors are enhanced by an organizational culture that support innovation Therefore, employees who work in a supportive environment
express more job satisfaction
The relation between organizational culture and job satisfaction has also
been studied in terms of demographical characteristics The results seem to be
similar both for eastern and western type organizations and cultures Sommer et
al (1996), for instance, found that job commitment of employees from Koreawas positively correlated with their positions, tenure and age It indicates thatolder employees, who held higher positions and for longer time reported higher
levels of job satisfaction and job commitment The same study, however, found
no statistically significant correlation between educational level and job
commitment among employees of western countries
From all the above, it can be supported that organizational culture are important organizational antecedents of job satisfaction Moreover, the results of
recent researches strongly support that there is a link between organizationalculture and job satisfaction

of organizational culture and employees' job satisfaction is illustrated in Figure
2.1 below In this theoretical framework, organizational culture dimensions are
independent variables and employees' job satisfaction is a dependent variable.
[he present study thus attempts to bridge the gap by providing a basis for a
thorough and insightful discernment of organizational culture and job
satisfaction The model suggests that the greater the extent to which these five
Trang 30Independent Variable: Organizational Culture Dimensions
This measure is based on the five dimensions of organizational culture
dimensions questionnaire developed by Business Research Lab (as mentioned in
literature review) with appropriate changes to make the items more relevant to
the present study The five dimensions which consist of 20 items aresupportiveness to individual initiatives (HH); Rewards and Recognition (RR):Ethical Behavior (EB), Balance of work and family life (BW), and Carrier
Development (CD)
Dependent Variable: Job Satisfaction
The instrument used to measure overall job satisfaction is Brief Index of
Affective Job Satisfaction (BIAJS) designed by Thompson & Phua (2012) This
is 5-iteam questionnaire assess the overall employees’ job satisfaction
Trang 31Both questionnaires were translated to fit Vietnamese staffs 5 officers at
VNABC have revised and recommended some changes to make _ the
questionnaire clearer
2.2.3 Hypothesis:
There are several hypotheses for this research model as following:
- HI: Reward and Recognition component and job satisfaction have a positive relationship That means the higher/lower customer evaluate tangible
factor, the higher/lower level of customer satisfaction
- H2: Ethical Behavior component and customer satisfaction have a positive
relationship That means the higher/lower customer evaluate reliability factor, the
higher/lower level of job satisfaction.
- H3: Individual Initiative component and customer satisfaction have a
positive relationship That means the higher/lower customer evaluate responsiveness factor, the higher/lower level of customer satisfaction.
- H4: Balancing of work component and customer satisfaction has apositive relationship That means the higher/lower customer evaluate assurancefactor, the higher/lower level of customer satisfaction
- H5: Carrier Development component and customer satisfaction have a
positive relationship That means the higher/lower customer evaluate empathyfactor, the higher/lower level of customer satisfaction
2.2.4 Data Collection and Analysis
Each participant in the study received a survey packet that contained thefollowing items: a cover letter explaining the purpose of the study and providing
instructions for using the test instruments, Brief Index of Affective Job Satisfaction (BIAJS), the Organizational Culture Dimensions Questionnaire (OCQ) and an information survey to assess specific demographic information It
was stressed to all participants that their participation was completely voluntary
Trang 32Researcher came to several companies with the reference letter from VietnamAssociation of Business Culture Development to do the survey However, there
is limit of time so research sent email with an online survey (created by Google
drive) Administration of the test instruments took place during early April 2015.
Then, data will be input and screened to identify missing samples After
rejecting all invalid samples, data will be encoded as in the following table:

L
Trang 34The data collected will be cleaned and processed by software SPSS 22.0
Some methods of processing data used in this study are as following:
a Reliability analysis by Cronbach's alpha
Cronbach’s alpha is a common measure of internal consistency
(reliability) of a test or scale Internal consistency describes the extent to which
all the items in a test measure the same concept or construct and hence it is
connected to the inner-relatedness of the items within the test (Tavakol ef al., 2011) Cronbach’s alpha is most commonly used when researcher has multiple
Likert question in a survey or questionnaire that form a scale and the researcher
wishes to determine whether the scale is reliable (Laerd statistics).
The value of alpha (a) may be between negative infinity and 1 However,
only positive values of alpha have meaning In general, alpha coefficient ranges
in value from 0 to 1, and the increase of this value means that the correlations
between the items increase (Amit Choudhury, 2010) Therefore, this processing
data method helps analyst assess the reliability of scale through Cronbach’s alpha
coefficient A commonly accepted internal consistency using Conbach’s alpha is
as follow:
Table 2.3: Cronbach's alpha values and internal consistency
Cronbach's alpha | Internal consistencya>0.9 | Excellent
0.9>a >0.8 Good0.8 >a 20.7 | Acceptable0.7 >a> 0.6 Questionable
As the table shows, an acceptable reliability score should be 0.7 or higher.
However, lower thresholds are sometimes used in the literature (Reynaldo et al
1999) In this research, scales which have Cronbach’s alpha coefficient greater
than or equal to 0.6 will be accepted
Trang 35Besides assessing the reliability of scales, Cronbach’s alpha analysis also
helps to check whether any item is not consistence with the rest of the scale
through item-total correlations Item-total correlation performs the correlation ofone variable with others in the same scale; the higher correlation value, the better
correlation between that item and the others Variables which have greater than
0.3 item-total correlations will be accepted; the others which have smaller than
0.3 item-total correlations will be eliminated from analysis data.
b Exploratory factor analysis
Exploratory factor analysis is a powerful statistical technique which isused for data reduction and summarization The primary objectives of anexploratory factor analysis are to determine (1) the number of common factors
influencing a set of measures; (2) the strength of the relationship between each
factor and each observed measure (DeCoster, 1998)
At first, it is necessary to test the sampling adequacy of factor analysis
base on Kaiser-Meyer-Olkin (KMQO) Measure In case of KMO has valuebetween 0.5 and 1.0 and Sig is smaller than 0.5, factor analysis is more
appropriate factor analysis In case of KMO has value smaller than 0.5 or Sig isgreater than 0.5, it indicates that factor analysis may not be appropriate
By performing exploratory factor analysis, investigator can decide the
number of factors to extract in the model The Kaiser creation states that
investigator should use a number of factors equal to the number of the
eigenvalues of the correlation matrix that are greater than one (DeCoster, 1998)
In this research, the eigenvalues will be plot in descending order, then thenumber of factor will equal to the number of eigenvalues that occur prior andhave greater than 1.0 values
An important part in exploratory factor analysis is interpreting factormatrixes This research will use Varimax rotation process to produce multiple
group factors Factor loadings which indicate correlations between the variablesand the factors are required to have greater than 0.5 values Then, a factor can beinterpreted in terms of the variables that have high load on it
Trang 36c Regression analysis
Regression analysis is a modeling technique for analyzing the relationship
between a real-valued dependent variable Y and one or more independentvariables X;, Xz, X: X, (Ragsdale, 2007), The goal in regression analysis is to
identify a function that describes the relationship between these variables as closely as possible so that we can assess the impact of each independent variable
on dependent variable as well as predict the change in dependent variable when
there is any change in independent variables
The regression model in this research is:
Y =bo t+ by) Xj) + by X.+_ +b Xe +e
Where:
- Y=Scores on the customer satisfaction towards Military Bank
- XX, Xo X, = Scores on the attitude towards the quality components
(tangible, reliability, responsiveness, assurance, empathy)
- by, bo k= Regression co-efficient of independent variables
- bo=an intercept
- €=anerror term
At first, it is necessary to test assumptions for regression analysis Theprincipal assumption is that there is a linearity of the relationship betweendependent and independent variables This research investigates the model withmore than one independent variables, the correlation among independentvariables (multi-collinearity) should be checked Variance inflation factor (VIF)
is used to measure the multi-collinearity in this regression analysis Regression model accept variables which have VIF smaller than 10 If VIF for one variable
is around or greater than 10, there is collinearity associated with that variable;this variable should be removed from the regression model In addition, it isassumed that the error terms £ are independent, normally distributed random
variables with mean value of 0, and constant variances As long as theseassumptions are not seriously violated, regression model will be established
