from the basic analysis as well as some ad hock
reports derived from characteristic analyses
specified by a manager through the graphic interface.
Furthermore, these results are used to update
customer segments dynamically so as to yield
different marketing strategies applied to different
customer segments.
CRM typically means that the lifetime value of a
customer is to be maximized by maintaining two
way communications between the customer and the
company through the Internet. This concept is
limited in that the potential customers are not
addressed explicitly. By combining POS data with
transaction data on the Internet, not necessarily
linked to purchasing, it is now possible to capture
the entire market as depicted in Figure 1, where the
market is decomposed into 9 segments: (Existing-
Active, Existing-Sleeping, Potential) × (Not
Important, Normal, Important). The arrows (1)
through (7) indicate the desirable changes of the
market for the company, whereas the arrows (8)
through (12) represent the changes of the market to
be avoided. The new marketing approach for
enhancing CRM would then be to devise strategic
moves so as to promote the moves along favorable
arrows and prevent the moves along unfavorable
arrows. Since such customer segments have to be
updated dynamically, the profile vector approach
becomes crucial for containing the underlying
computational burden. This example demonstrates
the importance of the 70-30 principle in e-Marketing.
For establishing a base for computer supported
education through this example, where students can
learn how to develop and maintain the dynamic
customer segmentation system illustrated in Figure 1
based on the 70-30 principle, a computer simulator
for the dynamic customer segmentation system is
installed in a server at Sumita Research Laboratory
in parallel with the system developed at the
collaborating e-business company through the joint
research project. Real data collected from the
Internet are fed into the simulator once a week. This
simulator enables students to actively get involved in
the decision process for development and analysis of
e-marketing strategies.
3 CONCLUSIONS
In the matured market economy, consumers are
interested in acquiring goods and services that others
may not have but fit their particular needs so as to
maximize their own sense of satisfaction. Naturally,
this trend results in a variety of products and

services in small quantities and the market
segmentation becomes extremely important. Such
products introduced in response to segmented
submarkets would have much shorter life cycles,
causing rapid changes in the segmented submarkets.
In this paper, we propose a general scheme
involving methodologies and tools for capturing
such rapidly changing environments.
The proposed general scheme is based on the 70-
30 principle, proposed by the authors in (Sumita and
Yoshii, 2012), applied to the information processing
procedures, where such procedures for separate
segmented submarkets are designed 70% in common
with remaining 30% for customization so as to cater
for peculiarities of individual submarkets. The key
success factor for development of the general
scheme is to introduce profile vectors as an
