Introduction
•Challenge for manufacturers and retailers to acquire and retain customers
•Spend huge amounts in promotions to draw more customers
•Understanding buying behavior of customers of utmost priority
•Coupon promotions – major vehicle used for marketing
![Page 4: BI.004.03.Presentation.Coupon Redemption - Power to Predict Valued Shoppers](https://reader035.fdocuments.in/reader035/viewer/2022070515/587c0e991a28ab03768b6239/html5/thumbnails/4.jpg)
Project Motivation
•Marketer’s dilemma: “Who should be offered discount in order to maximize sales and how much?”
•Challenge: To identify loyal buyers amongst the shoppers who redeem coupons
•Use of pre-offer shopping history of shoppers to predict which of them are most likely to repeat purchase after being exposed to a coupon offer

Data•First hand data obtained from the client •350 million rows of transactional data for over
300,000 shoppers•Only one offer per customer
![Page 6: BI.004.03.Presentation.Coupon Redemption - Power to Predict Valued Shoppers](https://reader035.fdocuments.in/reader035/viewer/2022070515/587c0e991a28ab03768b6239/html5/thumbnails/6.jpg)
The Challenge
•No ready predictor variables available•To mine this huge data dump and identify variables
that could be used as predictors in the model•Create variables using existing research and our
intuition•Existing techniques : Descriptive – RFM•Pareto Principle•Offer Attractiveness
![Page 7: BI.004.03.Presentation.Coupon Redemption - Power to Predict Valued Shoppers](https://reader035.fdocuments.in/reader035/viewer/2022070515/587c0e991a28ab03768b6239/html5/thumbnails/7.jpg)
Variable Creation•No. of transactions by the customer for the product
on offer•Amount spent by the customer for the product on
offer•No. of items bought by the customer for the product
on offer•No. of days since last purchase for the product on
offer •Similar variables for category, brand and company•Offer value for the product on offer
![Page 8: BI.004.03.Presentation.Coupon Redemption - Power to Predict Valued Shoppers](https://reader035.fdocuments.in/reader035/viewer/2022070515/587c0e991a28ab03768b6239/html5/thumbnails/8.jpg)
Variable Creation
•No. of pack-sizes for the product on offer•No. of competitors for the product on offer•No. of times the product was bought in the last 30 days•No. of transactions in the store in which the offer is
made•Total units sold of the brand on offer•Average price of the product on offer•Market share of the product vis-à-vis the category •No. of return transactions for the product on offer

Variable Creation
•No. of transactions on discount – discount proneness•Day of the week•Store size•Tenure of the product on offer

Data Pre - processing•Reduced skewness of input variables by using
Transform Variables node and log as transforming method

variables are selected•Target variable ‘repeater’ is a binary variable with
value either t or f (true or false)

Implications• Past purchases made in the brand and category for which the
coupon was offered are the strongest predictors of repeat purchase
• More the price of product, more the probability of customer to repeat the purchase
• As the number of days since the brand or category for which the coupon was offered increases, the probability or repeat purchase decreases
• Besides, the store in which the coupon is offered, Product size assortment and Success ratio of a product also plays a small but important role in predicting repeat purchase.

Business Implications
• Loyalty plays a huge part in estimating repeat purchase
• Product pricing and promotion location also plays a significant role
• Better understanding of the customer behavior
• Marketing strategy planning
• Managing the budget effectively
