Data Mining in CRM ...Data Mining in CRM ...
“ ...through data mining – the extraction of hidden predictive information from large databases – organizations can identify valuable customers, predict future behaviors, and enable firms to make proactive, knowledge-driven decisions.”

IntroductionIntroduction Product-oriented view VS. Customer-oriented view
Design-build-sell VS. sell-build-redesign One-on-one marketing VS. mass marketing Goal of revolution: Establish a long term relationship with each customer
The advent of the Internet and technological tools accelerate modern CRM revolution CRM is important for B2C or C2B, and even more crucial in B2B environments

Why Data Mining?Why Data Mining? Between businesses and customers…
Collecting customer demographics and behavior data makes precision targeting possible Helps to devise an effective promotion plan when new products developed Creates and solidifies close customer relationships
Between businesses… Helps to smooth transactions, communications and collaboration Simplifies and improves logistics and procurement process

What is Data Mining?What is Data Mining? “…a sophisticated data search capability that uses statistical algorithms to discover patterns and correlations in data.” “…another way to find meaning in data.” Data mining is part of a larger process called knowledge discovery

What Data Mining is ~NOT~What Data Mining is ~NOT~
• Data mining software does notnot eliminate the need to know the business, understand the data, or be aware of general statistical methods.
• DM does notnot find patterns or knowledge without verification
• DM helps to generate hypotheses, but it does notnot validate the hypotheses

The problemThe problem
• Home equity marketer that extended home equity lines of credit at the national level.
• The client’s goal was to increase the efficiency of targeting current mortgage customers who might be interested in the client’s service.
![Page 29: Data Mining Techniques for CRM](https://reader035.fdocuments.us/reader035/viewer/2022081420/5681351f550346895d9c7fd5/html5/thumbnails/29.jpg)
The SolutionThe Solution
• CHAID identified 16 distinct market segments.
• In particular, one particular segment accounted for 65% of responses to the mailing.
![Page 30: Data Mining Techniques for CRM](https://reader035.fdocuments.us/reader035/viewer/2022081420/5681351f550346895d9c7fd5/html5/thumbnails/30.jpg)
ResultsResults
• The highest-rated group from the predictive model had by far the highest response rate to the equity line of credit campaign—85% above average for the direct mailing,
• The goal of the program was a 10% increase in response rate, but the actual response rate increased 30%.
• The firm was able to increase profits by over one million dollars in the first year after implementation.

Clarity and explicabilityClarity and explicability- CHAID model is understandable as a set of rules- Neural Network is obscure
Implementation/integrationImplementation/integration- The CHAID model is much easier to be
implemented that a Neural Network.- The risk of missing code by an IT department is
slim for a CHAID model and higher for a Neural Network.
![Page 33: Data Mining Techniques for CRM](https://reader035.fdocuments.us/reader035/viewer/2022081420/5681351f550346895d9c7fd5/html5/thumbnails/33.jpg)
Data RequirementsData Requirements- The data for both techniques requires some
pre-processing. - Neural Network require the data be
transformed into binary format.
Accuracy of modelAccuracy of model- Neural Networks provide more accurate
models, especially for complex problems.
![Page 34: Data Mining Techniques for CRM](https://reader035.fdocuments.us/reader035/viewer/2022081420/5681351f550346895d9c7fd5/html5/thumbnails/34.jpg)
Construction of modelConstruction of model- CHAID is easier and quicker to construct.- Neural Networks have many parameters that
must be set and require more skilled manipulation.
CostCost- Building a Neural Network is more costly then
building a CHAID model.

AplicationsAplications- CHAID and Neural Networks can create
predictive models.
- Neural Networks can handle both categorical and continuous independent variables, but these have to be transformed to 0/1 input variables.
- When all or most of the independent variables are continuous, neural networks should perform better than CHAID.
![Page 36: Data Mining Techniques for CRM](https://reader035.fdocuments.us/reader035/viewer/2022081420/5681351f550346895d9c7fd5/html5/thumbnails/36.jpg)
AplicationsAplications- The Neural Networks and CHAID can be used
to solve sequence prediction problems.
- Neural Networks can be used to solve estimation problems.
- CHAID provides good solutions to classification problems, can be used for exploratory analysis and can provide descriptive rules.
- An interesting development is the combination of these two techniques to create “neural trees”.

CONCLUSIONS CONCLUSIONS - The choice among different
options is not as the choice to use data mining technologies in a CRM initiative.
- Data Mining represents the link from the data stored over many years through various interactions with customers in diverse situations, and the knowledge necessary to be successful in relationship marketing concepts.
![Page 38: Data Mining Techniques for CRM](https://reader035.fdocuments.us/reader035/viewer/2022081420/5681351f550346895d9c7fd5/html5/thumbnails/38.jpg)
- Through the full implementation of a CRM program, which must include data mining, organizations foster improved loyalty, increase the value of their customers, and attract the right customers.
- As customers and businesses interact more frequently, businesses will have to leverage on CRM and related technologies to capture and analyze massive amounts of customer information.
CONCLUSIONS CONCLUSIONS

CONCLUSIONS CONCLUSIONS
- CRM solutions focus primarily on analyzing consumer information for economic benefits, and very little touches on ensuring privacy.
