Problem on CRM

Ignorant about customer behaviours

Objectives

Customer Segmentation

New Campaign

DATA COLLECTION

1. csv format

2. Txt format

5

ETL PROCESS

Extract Extract tab separated data from txt file using bash shell & regular expression

Transform Male to m

Female to f

Business_call to 1

Non_business_call to 0

Load Load data to mysql database using python script

OLAP DESIGN

Purpose:

Slice, Dice, Roll up, Drill Down operation

Design Basis:

4 dimension representation

DATA MINING

1. RFM Methods

R Recency (x axis)

F Frequency (y axis)

M Monetary (z axis)

Step

Attribute Selection & K-means Clustering

Objective

Customer Segmentation

How?

1st clustering -> Diamond, Gold,

Silver …

2nd cluster -> Demographic

cluster

Now compare cluster based on

attribute value

Objective

Churn Prediction through call

diameters

How?

Predict customer with value

outside 90% confident range

Accuracy?

With increase in data size->

accuracy increase

RESULT & CONCLUSION

With the implementation of this software, telecommunication will be able to

know more about customer & their call behavior

Customer Segmentation help them

1.To maintain effective customer relationship management

2.To launch specific offers focusing on specific groups

Alert them about customer churn behavior

LIMITATION & FURTHER ENHANCEMENT

Limitation

Data load time is high

Our System Isn’t customizable for all query

Further Enhancement

Customer Segmentation accuracy could be improve by including customer life time value & apriori algorithm

Reporting tool could be made more general & flexible

Competitor Analysis
