Abstract: At present, information has increasingly become a critical resource in all organizations. And the information
quality is one of the key factors which may influence the quality of leaders’ decisions and organizations’
actions. In the complex and changeable environment, the one who can accurately grasp market information
can succeed. So enterprise information quality management comes into being. In a word, this is a kind of
enterprise information management which based on the quality management. This paper is aimed at telling a
way that how to carry out the enterprise information quality management in enterprise through the theory of
quality function deployment.
1 INTRODUCTION
The enterprise information management faces two
problems. One is how to avoid heavy loss if the
information quality is so poorly. Another is how to
choose the valuable information to help the
enterprise to make the correct strategic decision.
This study introduces a reliable and feasible
method to help enterprises to manage information
effective when they are facing information quality
problems. This method bases on QFD theory. It
helps us to construct an information management
model which uses to plan, control and improve
enterprise's information management activities.
2 THE ENTERPRISE
INFORMATION QUALITY
MANAGEMENT RESEARCH
STATUS
At present many researchers have fully realized the
importance of improving the information quality. In
recent years, many researchers have done much
research and made some achievements, but there are
also many problems to be solved because of the
particularity and complexity of the information.
♦ Many information quality management
methods stay in theoretical level;
♦ Most of the research is aimed at a particular
type enterprise, which is lack of general
significance;
♦ Information quality assessment doesn’t pay
enough attention to the detail information
quality of each step;
♦ Most methods are afterwards evaluation, the
research about how to evaluate information
quality and discover information quality
problems early in the research are also
insufficient;
♦ Information quality improvement method
research should be further studied.
3 THE THEORY OF QFD
Quality function deployment (QFD) is a kind of
systematic decision-making techniques. In the design
phase, it can change the customer requirements into
the product definition exactly. In the phase of
production preparation, it will ensure that the product
definitions which reflect customer demands can
change into the products manufacturing process
requirements correctly. In production processing
phase, it will ensure that the products fully meet the
requirements of customers.
Obviously, QFD is a product development
method which customers play an important role. Its
purpose is that enterprises can make the product with

the fastest speed, the lowest cost and optimal quality.
House of quality (HOQ) is an effective way to
link the customer requirements and the performance
of production. It plays a core role in QFD. And it is
made of seven different matrixes.
♦ The customer requirements;
♦ Product characteristics;
♦ The importance of customer requirements;
♦ Planning matrix;
♦ The relationship between the product
characteristics and customer demand;
♦ The relationship between characteristics;
♦ The target.
4 ENTERPRISE INFORMATION
QUALITY FUNCTION
DEPLOYMENT
4.1 The Feasibility of Enterprise
Information Quality Function
Deployment
♦ QFD theory is a kind of management thoughts
and there is no fixed mode to follow.
♦ The objects of enterprise information
management are information and information
activities.
♦ The quality management thoughts are built on
the basis of process. Therefore, if the
information is seen as a product, it will be
possible to research the information quality by
using QFD.
4.2 The Model of Enterprise
Information Quality Function
Deployment
According to the characteristics of enterprise
information management, the model that we will set
up is divided into two parts: the first part is the needs
of information users, quality elements and the factors
affecting the quality. The second part is the process
about changing the information users' needs into
information quality elements and changing
information quality elements into the factors
influencing quality by HOQ, and then we can find
out the key point in enterprise information quality
management. The model is shown in figure 1 (Fig.
1).
4.3 The Steps of Enterprise
Information Quality Function
Deployment
♦ Determine the needs of information users. The
enterprises should have an investigation about
the needs of information users.
♦ Make an important sequence about the needs.
The AHP method can be used in this step.
♦ Determine the quality of information factors.
♦ Construct information users' needs - quality
factors relation matrix. There are two things
need to be done. One is constructing
information users' needs - quality factors
relation matrix. Another is judging the
relevance.
♦ Determine the factors which influence the
information quality.
♦ Construct information quality factors - factors
influencing information quality relation matrix.
The method uses in this stage is similar to the
fourth step uses.
♦ The output result analysis. Obtaining the
information above, the enterprise can recognize
the key point and take measures to ensure the
information quality. So they are very useful.
4.4 The Existent Problems
♦ The principal of enterprise information
management may ignore some demands of
information users. This may cause some
information system users cannot find the
information which they need.
♦ The choice of Enterprise information quality
factor. At present, there is no consistent
conclusion about how to select the information
quality factors. So the enterprise should choose
the right factors according their own situation.
♦ When we carry on the analysis that the
importance of factors and judge the relevance of
the two relation matrixes, there are some faults.
For example, the method we use may not
quantitative.
4.5 The Output Result Analysis
Obtaining the information above, the enterprise can
recognize the key point and take measures to ensure
the information quality. So they are very useful.

5 COMPLIMENTARY
This paper tells a way which bases on the QFD
theory and it is about how to carry out the enterprise
information quality management. It may be an
effective way and helpful for enterprises. However,
there are also many problems worth to study.
