tomer call--or at least a synopsis of the call or call outcome~is archived and
numbered in a consistent way for retrieval purposes.
However, as more electronic customer interactions are passing through
multi-channel contact centers there is a greater need to provide case manage-
ment tools to ERMS (or e-channel management) applications.
Categorization
Customers typically make contact with a contact center if they have a particu-
lar type of problem or a certain information need. Over time, the nature of
customer queries can be categorized. In the case of a retail bank, for example,
customer queries would typically fall into one or more of 400 categories.
Often a customer will make contact with multiple queries (e.g, "I need my
bank balance" and "I want information on your latest high-interest savings
account." Categorizing voice calls is relatively easy in that the ACD menus
should allow the customer call to be categorized and routed. However, most
categorization engines fail because they cannot cope with multiple simultane-
ous categorizations. In this respect text based categorization is potentially
more powerful. A customer can type multiple queries into a dialog, and the
text categorizer can apply multiple categories to the customer query, each of
which will have to be resolved before the case can be closed.
Churn
Churn is simply the term for customer turnover or attrition during the course
of a year. So a churn rate of 5 percent implies that 5 percent of the total cus-
tomer base leaves during the course of a year. Minimizing customer churn is a
key objective for many CRM implementations. However, it has to be recog-
nized that a degree of natural churn is to be expected (e.g., customers die or
leave the country). However, defection of high-value customers to the compe-
tition always needs to be minimized. Analytical tools can determine the nature
of customer churn, and primary research can be very useful in determining
likely causes for churn and pointers towards churn-reduction strategies.
