Successful software – like information system is meaning nothing if the work is not supported by correct and high quality data, what
means, that the data are an important part of software or application especially data applications. Increasing quantity of data and
demand for integrated and complex data applications requires high quality in data modelling and data. New concepts, tools and
techniques for a database modelling, development and retrieval are required with a final goal: better data and information quality.
One of the possible solutions for higher data quality is the integration of cultural aspects. Cultural aspects include different
viewpoints, including country dependent parameters and business and domain dependent cultural issues. As a consequence, data
quality as well as information quality of applications - software improves if the mentioned approach is applied. In this paper the
influence of cultural issues on the data quality dimensions and Deming’s Fourteen Points will be presented and discussed.

1. INTRODUCTION
To improve data quality demands in today increasing quantity of data, various approaches are used.
Unfortunately quite often these approaches only vaguely take into consideration that the prerequisite for
the high data quality are data quality dimensions. The majority of such approaches do not take into
account the influence of cultural issues.
Information technology has automated many operations and made data available to more applications
and people. However, the progress of information technology also had an impact on data quality by
worsening it. Because users often assume that digital data are correct, the guilt if often put on data and
its incorrectness. These problems can grow out of proportions especially in data warehouses and big data
environments, as well as on the Internet [Welzer 1998], [Welzer 2013]. The data quality dimension needs
to get a new presentation and understanding which includes cultural issues.
In general data quality is multidimensional and complex, and involves not only data management and
modelling but also analysis, quality control and assurance, storage and presentation. As stated by Strong
et al. [Strong 1997], data quality is related to a specific use case and cannot be assessed independently of
a specific domain and / or user. In a database the data does not have actual quality or value [Dalcin 2004]
it only has potential value which is harvested when data is used. In addition, English has introduce
information (data) quality as data’s ability to satisfy customers and to meet customers’ needs [English
1999], whereas Redman, suggested that data must be accessible, accurate, timely, complete, consistent
with other sources, relevant, comprehensive, provide a proper level of detail, be easy to read and easy to
interpret [Redman 2001]. In such a sense a data administrator needs to consider what may need to be
done with the data to increase its usability, increase its potential use and relevance, and make it suitable
for a wider range of purposes and users [Chapman 2005].
To fulfil Chapman’s statement and the before discussed finding we have to give the conceptual view of
data much more attentions by incorporating data quality dimensions and cultural issues. The later have
to be incorporated and business and domain aspects have to be considered.
In Chapter 2 we will briefly present some notions, including data and information quality, quality
dimensions and Deming’s Fourteen Points. An overview of cultural issues is described in chapter 3. The
main goal of chapter 4 is to introduce the influence of cultural issues on data quality dimensions and

Deming’s Fourteen Points. Finally we will conclude with a summary of the proposed concepts and future
research in chapter 5.
2. DATA QUALITY, INFORMATION QUALITY AND DATA QUALITY DIMENSIONS
The concept of quality is difficult to describe because of its amorphous nature and various definitions
presented by different authors. This results in the facts that different authors tend to emphasize different
aspects of quality [Fox 1997]. When the quality concept was defined, the emphasis was given on how to
achieve quality and how to make it compliant with a standard or a specification. Rapid changes in later
years have led to new definitions of quality. One of the most well-known and recognized definitions is the
IEEE standard definition [IEEE 1998] in which quality is defined as the totality of features and
characteristics of a product or service that bears on its ability to satisfy given users’ needs.
For further discussion the most important definitions are those of data quality and information
quality, as well as the definition of quality dimensions, which are as well presented by different authors.
T.C. Redman defines the data quality in its broadest sense. In his book Data Quality for Information
Age [Redman 1996] he implies to data quality definition the relevance of intended uses and sufficient
details as well as quality with a high degree of accuracy and completeness, consistent with other sources
and presented in appropriate ways.
Giri Kumar Tayi and Donald P. Bollou as guest editors of Examining Data Quality in the
Communications of the ACM, have defined the term data quality as fitness for use which implies that the
concept of data quality is relative [Tayi 1998]. Data appropriate for one use may not possess sufficient
quality for another use. Or opposite, already used data comply with some kind of quality. A related
problem with multiple users of data is also that of semantics. The data designer and/or initial user may
fully agree with same definitions regarding the meaning of the various data items, but probably other
users will not share the same view. Such problems are becoming increasingly critical as organizations
implement data warehouses, using big data or taking into account different cultural aspects, according to
business and expert areas. At the same time the conceptual view on data including cultural issues is more
and more important owing to the facts that it can a possible solution for the mentioned problems.
The data quality definition of Ken Orr [Orr 1998] introduces a kind of measurement view on the term.
It is defined as a measure of the agreement between the data views presented by an information system
and the understanding of the same data by the user. Data administrator wants to ensure that data is
accurate enough, timely and consistent for the enterprise to survive and make reasonable decisions.
However, the most significant problem of data quality is the facts that it often changes. Data in a
database is mostly static, but in the real world it is rapidly changing. One reason more to apply a
conceptual view influenced by cultural issues.
If defining and understanding data and data quality is difficult and it varies, then defining and
understanding information is a hornet’s nest. In some environments the term information mistakenly
refers to both data and information [Strong 1997]. Data usually refers to information at their early stages
of processing and information to the product at a later stage when the meaning is added. Rather than
switching between the terms information is used to refer to data or information values at any point in the
process. But still we must bear in mind that different information definitions depend on different points of
view. For example:
• From the information management point of view, information is simply processed data
[Redman 1996].
• From the information theory point of view, information is the non-redundant part of a
message [Redman 1996].
• From the information technology for management point of view, information is data that has
been organized in a way that is has meaning to the user [Turban 1996]
However once a point of view is fixed, no conflict should arise. Once again it is important to emphasize
that the prerequisite for information quality is data quality.
But to get a better view on data quality, particularly from the conceptual point of view, data quality
dimensions have to be introduced. Redman defined for the users’ perspectives 15 characteristics of an
ideal view [Redman 1996]:
Influence of Cultural Issues on Data Quality Dimensions • 10:77
• Relevance – data that is needed by the application;
• Obtainability – values should be easily obtained;
• Clarity of definition – all terms should be clearly defined;
• Comprehensiveness – all required data should be available and included;
• Essentialness – unneeded data should not be included;
• Attribute granularity – right level of definitions and abstractions for data;
• Domain precision – appropriates of domains;
• Naturalness – existence in the real world;
• Occurrence identifiability – identification of entities (data);
• Homogeneity – minimization of unnecessary attributes;
• Minimum redundancy;
• Semantic consistency – clear and consistent view;
• Structural consistency;
• Robustness – wide view;
• Flexibility – easy to change.
We also have to emphasize Deming’s Fourteen Points. Deming defined his 14 points or key principles
with the intention to make easier implementation of changes in companies, departments and teams. They
are a guide to the importance of building users awareness. And from that point of view it is important to
introduce cultural issues into data quality dimensions.
3. CULTURAL ISUESS
One of the most familiar words in any community is culture. The word itself is used in different
combinations and meanings, which leads to many definitions of culture. Culture can be presented as an
artistic activity, as a social, philological or anthropological concept or as a culture of groups, societies and
countries. The world itself has grown over the centuries to reach its currently broad understanding
[Baldwin 2004]. However, culture is not something that we simply absorb; it is something that we have to
learn although the common knowledge is mostly opposite.
The area of culture has been studied by well-known researchers and we are faced with different
definitions and explanations that are showing us authors’ point of view on the topic [Welzer 2011].
Hofstede for example defined culture as a collective phenomenon, because it is shared with people who
live or lived within the same social environment. According to Hofstede culture consists of unwritten rules
of social game. It is the collective programming of the mind that distinguishes the member of one group or
category of people from others [Hofstede 2001]. Lewis, another important researcher, explains that the
culture is an integrated pattern of human knowledge, a core belief, and a behaviour that depends upon
the capacity for symbolic thought and social learning [Lewis 2007]. Culture also refers to the cumulative
deposit of knowledge, experience, beliefs, values, meanings, hierarchies, religion, notions of time, roles,
spatial relations, concepts of the universe and material objects and possessions acquired by a group of
people in the course of a generation through individual and group striving [Schneider 2003]. If people
adjust to cultural differences, they can better face challenges and become better in their own profession
[Welzer 2010].
The summary of all these different, but also similar definitions, is the definition given by Rossinski,
which understand culture in the frame of a group as a set of unique characteristics that distinguishes its
members from another group [Rossinski 2003]. This definition can be easily applied to nations and
subgroups, as well as business environments (business and corporate culture) [Welzer 2010].
In addition to other important terms, there is also a very important term: cultural awareness. None or
poor cultural awareness means a poor understanding of cross-cultural dialogue, which can lead to
blunders and damaging consequences, especially in business, management and advertising, where
cultural awareness seems to be of key importance for success. However, engineering, medicine and many
other areas are also not immune to it [Hofstede 2004]. According to the definition, cultural awareness is
the foundation of communication, and it involves the ability of observing our cultural values, beliefs and
perceptions from the outside [Hofstede 2004]. Cultural awareness is important in communication with
people from other cultures, and we have to understand that people from different cultural societies might
see, interpret and evaluate things in different ways.
10:78 • T. Welzer, M. Hölbl, L. Nemec Zlatolas and M. Druzovec
A good illustration of culture and cultural awareness can also be found in cultural levels, as defined by
Alvesson and Berg [Alverson 1992]. They introduced different levels within the concept of culture
[Alverson 1992]: culture in societies and nations, regional and local, business cultures, organizational and
corporate, functional subcultures at the organizational level, social groups in the organization,
professional and functional cultures. The numbered levels contain subgroups, or rather, specific cultures
according to social life, geographical location and business domain, including enterprise and
organizational culture [Welzer 2011]. Such a definition of culture is probably more comprehensible to
engineers and other business and technical groups because they are more familiar with this presentation
of culture.
4. CULTURAL ISUESS AND DATA QUALITY DIMENSIONS
Quality and culture on their own represent two big areas of research and bear high importance in
development of new products as well as in behaviour of users. In this paper we would like to introduce the
influence of cultural issues on data quality dimensions. In Chapter 2, 15 characteristics and Deming’s
Fourteen Points adapted for data are presented and are an important introduction to this chapter.
According to 15 characteristics as well as fourteen points an introduction the possible cultural issue
was done:
• Relevance – data needed by the application – different cultural point of view can provide
different data needed
• Obtainability – values should be easily obtained – according to cultures and flowing laws, the
obtaining of some data could be not as easy as expected
• Clarity of definition – all terms should be clearly defined – we can find different definitions for
same or similar data in different environments
• Comprehensiveness – all data needed should be available and included – some cultures may
not allow the collection of some data
• Attribute granularity – right level of definitions and abstractions for data – it must be clear
what are sensitive data for which cultures
• Domain precision – appropriates of domains – culture sensitives of domains
• Naturalness – existing in real world – counterpart in the real word can differentiate from
culture to culture
• Occurrence identifiability – identification of entities (data) – different points of view in culture
• Homogeneity – minimization of unnecessary attributes – some of the attributes can be results
of cultural differences
• Semantic consistency – clear and consistent view – strong cultural influence
• Robustness – wide view – generalization in the cultural point of view
• Flexibility – easy change – limitations from cultural point of view are possible.
In addition, points of view of influence of cultural issues on data quality dimensions is given by
Deming’s Fourteen Points for quality management, adapted for data [Redman 1996]. Through this the
new philosophy of understanding quality from cultural point of view is becoming even stronger [Redman
1996], [Welzer 1998], [Welzer 2013]:
• Point 1 – Recognize the importance of data and information to the enterprise. Same data has
different meanings and importance in different enterprises and so also cultures.
• Point 2 – Adopt new philosophy. The enterprise can no longer live with currently accepted
levels of data quality. Introducing cultural issues is confirming this point.
• Point 3 – Cease dependence on error detection. Eliminate the need for error detection by
building accuracy and other quality attributes into processes that create data. Culturally
influenced detection of errors.
• Point 5 – Constantly improving the systems by which data are produced and used to create
value for customers, the enterprise and its stakeholders. Introducing the cultural issues is an
improvement.
• Point 6 – Institute job training. Cultural awareness help individuals and organizations to
understand how the cultural issues impact data.
Influence of Cultural Issues on Data Quality Dimensions • 10:79
• Point 7 – Teach and institute leadership for supervisors on workers, who produce data.
Managers of organizations that produce data must become responsible for quality, not simply
numeric production. The entire enterprise productivity will improve with improved data.
Cultural point of view has to be introduce in those activities to confirm improvement for the
entire enterprise.
• Point 9 – Break down barriers between organizations. Application, functional and business
domain ensure a free flow of cultural awareness across the organizational boundaries.
• Point 12 – Remove barriers standing between data products and their rights to pride in their
work. Cross cultural awareness motivates designers to different solutions and models.
• Point 13 – Institute training on data and information, their roles in the enterprise and how
they may be improved. The training has to be supported by cultural issues and cultural
awareness.
• Point 14 – Create a structure in top management that recognizes the importance of data and
information and their relationships to the rest of the business. Cultural issues supports this
recognition and the top management can always find a support for understanding data in
existing models and applications.
5. CONCLUSION
There is no doubt that data quality is needed, but as with many other activities we have to agree on
adequate measures and this is highly demanding activity.
In the case of data quality we have the support different guidelines like Data Quality Dimension
Characteristics or Deming’s Fourteen Points. Deming’s Fourteen Points for Quality Management were
adapted for data by Redman [Redman 1996] and in this paper we have suggested an adaptation of
Deming’s Fourteen Points as well as 15 characteristic, taking cultural issues into consideration. In this
paper we have presented characteristics and points that could be adapted for cultural issues. Additionally,
we presented cultural issues and comments concerning them.
Cultural issues as well as comments are based on experiences and previous research [Welzer 2010],
[Welzer 2011], [Welzer 2013] about data (same or similar data) in different environments and cultures.
For example some cultures (business environments) are using maiden name (a possible attribute), while
some others do not use it at all and operate only with the family name (an attribute as well) from which
the maiden name can be derivate, but only in some environments and cultures, what do not guarantee an
easy obtainability, neither clear definitions and availability. Also attribute granularity, domain precision
and naturalness as well as semantic consistency and robustness are effected in this case. To obtain the
cultural issues in numbered characteristic as guidelines the Deming’s Fourteen Points adapted for data
can be used.
In further research policy and strategy has to be involved to make the guidelines clear and suitable for
testing in daily processes connected to data and quality.
