1️⃣ Objective
The objective of this capstone is to perform an in-depth analysis of e-commerce customer transaction data to uncover purchasing patterns, and then apply RFM (Recency, Frequency, Monetary) segmentation. The resulting segments will be used to identify High-Value Customers (HVCs) and Churn Risks, enabling the development of data-driven, personalized marketing strategies.
Key Goals:
✨ Data Cleaning & Exploration of a large transaction dataset (e.g., Online Retail Data).
✨ Calculate RFM scores for all unique customers and assign them to predefined segments.
✨ Apply advanced segmentation using K-Means Clustering on normalized RFM values to validate or refine segments.
✨ Characterize each RFM segment (e.g., ‘Champions’, ‘At Risk’) with key behavioral insights.
✨ Propose actionable marketing strategies tailored to maximize Customer Lifetime Value (CLV) for each segment.
2️⃣ Problem Statement
Generic marketing efforts often lead to poor return on investment and customer dissatisfaction. Businesses struggle to identify which customers are their most profitable, which are likely to churn, and how to effectively allocate marketing resources.
This project addresses this by providing a robust, quantitative method (RFM analysis combined with clustering) to transform raw transaction data into strategic, actionable customer segments. This allows for focused engagement, higher retention rates, and optimized marketing spend.
3️⃣ Methodology
The project will follow a standard Data Science workflow (CRISP-DM):
✨ Step 1 — Data Preparation: Load, clean, and preprocess the transaction data (handling missing values, calculating total sales, removing canceled orders).
✨ Step 2 — RFM Feature Engineering: Calculate Recency (days since last purchase), Frequency (total number of transactions), and Monetary (total money spent).
✨ Step 3 — RFM Scoring: Apply quintile-based ranking (1-5 or 5-1) to R, F, and M values, and combine them to create the RFM score (e.g., 555 for Champions).
✨ Step 4 — Clustering Analysis: Normalize RFM features (log/scaling) to prepare for clustering. Use the Elbow Method or Silhouette Score to determine optimal ‘K’ clusters. Apply K-Means Clustering.
✨ Step 5 — Segment Characterization: Analyze the mean R, F, and M values for each cluster/segment and assign meaningful labels (e.g., ‘Loyal Customers’, ‘New Customers’).
✨ Step 6 — Visualization & Recommendation: Visualize segment distribution (e.g., scatter plots, heatmaps) and develop targeted marketing recommendations for each segment.
4️⃣ Dataset
Key Process Areas:
✨ Publicly available e-commerce transaction dataset (e.g., Kaggle’s Online Retail Data).
✨ Synthetic or anonymized transaction data from an industry partner (if available).
5️⃣ Tools and Technologies
6️⃣ Evaluation Metrics
✨ Segment Distinctness: Qualitative analysis showing clear, non-overlapping average RFM values for each defined segment.
✨ Clustering Performance: Quantitative metrics like the Silhouette Score and the Inertia/WCSS plot to justify the chosen number of clusters (K).
✨ Customer Coverage: Proportion of the customer base successfully assigned to a meaningful segment.
✨ Actionability: Quality and relevance of the proposed marketing strategies derived from the segment characteristics.
✨ Replicability: Clear documentation ensuring the RFM model pipeline can be easily re-run with new data.
7️⃣ Deliverables
8️⃣ System Architecture Diagram
Transactional Data
Order IDs, Purchase Date/Time, Customer ID, Item Prices, Total Sale Value.
Customer Profile Data
Demographics, Loyalty Status, Subscription tier, Preferred contact channel.
Web & App Interaction Data
Browsing history, Cart abandonment, Page views, Support ticket activity.
RFM Calculation Engine
Calculates R (Days since last purchase), F (Total transactions), and M (Total spend) for each customer.
RFM Scoring & Quintile Assignment
Assigns a score (e.g., 1-5) to each R, F, M metric, creating a composite RFM score (e.g., 555).
K-Means/Clustering Segmentation
Uses unsupervised learning on RFM scores to identify natural, actionable segments (e.g., Champions, At-Risk).
Segment Data Store (e.g., CRM)
Feeds updated segment labels and scores back to CRM for immediate use by sales and service teams.
Targeted Campaign Platform
Sends customized communications (e.g., retention offers to At-Risk, loyalty rewards to Champions).
Customer Value Dashboard
Tracks the size and health of each RFM segment and measures the effectiveness of targeted campaigns.
