Study Notes
Customer Segmentation
- Customer segmentation is a method of dividing customers into groups or clusters based on common characteristics.
- It can be done using various customer demographic characteristics, such as occupation, gender, age, location, and marital status.
- Psychographic characteristics, such as social class, lifestyle, and personality characteristics, and behavioral characteristics, such as spending, consumption habits, product/service usage, and previously purchased products, can also be used.
Need of Customer Segmentation
- It helps in identifying the most potential customers.
- It helps managers to easily communicate with a targeted group of the audience.
- It improves the quality of service and customer loyalty via a better understanding of segments.
- It helps managers to design special offers for targeted customers, to encourage them to buy more products.
- It also helps in identifying new products that customers could be interested in.
Types of Segmentation
- RFM (Recency, Frequency, Monetary) analysis is a behavior-based approach to grouping customers into segments.
- It groups customers based on their previous purchase transactions.
- It filters customers into various groups for the purpose of better service.
RFM Model
- Recency (R): Who has purchased recently? Number of days since last purchase (least recency).
- Frequency (F): Who has purchased frequently? It means the total number of purchases (high frequency).
- Monetary Value (M): Who has high purchase amount? It means the total money customer spent (high monetary value).
- Each of the three variables (Recency, Frequency, and Monetary) can be divided into four equal quartiles (Q1-Q4), which creates 64 different customer segments.
Steps of RFM
- Calculate the Recency, Frequency, Monetary values for each customer.
- Filter out top/best customers.
- Calculate the quartiles of RFM values using qcut() function.
RFM Implementation in Python
- Use pandas module to group customers by CustomerID.
- Calculate Recency, Frequency, and Monetary values using lambda functions.
- Change the column names.
- Calculate the quartiles of RFM values using qcut() function.
Assignment
- Find another data set with at least 50,000 records.
- Use the Lambda function for aggregation in the Pandas module.
- Perform RFM model on the new data set.
- Give examples of its use on the downloaded data set.
Explore the concept of customer segmentation and understand how RFM (Recency, Frequency, Monetary) analysis is used to group customers into segments. Learn how segmentation helps in improving the quality of service, customer loyalty, and identifying new product opportunities.
