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.

4.1 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.
