A customer success story
Building a product recommendation engine for an e-commerce store
The Brand
A leading manufacturing company with revenue of $4 billon+ and presence in categories like internal hard drives, USB Flash drive, External hard drives, and external solid-state drives. Its one of the top 5 data storage device company in the world.
The challenge
Product management and product marketing had no ability to leverage data, and design cross-sell/up-sell strategies.
Multiple teams in multiple geographical locations presented a significant scaling challenge for a unified recommendation engine.
The data was disparate, distributed, and siloed. The years of data collected was not tapped and used to glean intelligence in a holistic manner.
There was no enterprise grade compute and data management platform. All the data and analytics workloads were disparately conducted in local systems.
Our design approach
Data Discovery Session
End-to-end data discovery sessions with stakeholders covering Marketing, Analytics, E-Commerce, and Individual Product Teams, to understand what data they were collecting and how do they measure the success of any action on cross-selling or up-selling that they take.
Detailed Data Audit
Exhaustive audit of product catalogue and transactions data across 24 product categories and 3500 product SKUs.
Top Products, Categories by Transactions

Databricks for Data Science
Azure Databricks has clusters that provide a unified platform for running production ETL pipelines, ad-hoc analytics, and machine learning that can auto scale. Interactive clusters are used to analyze data collaboratively with interactive notebooks. Job clusters are used to run fast and robust automated workloads using the UI by scheduling.
Data Transformation
The audit was followed by development of analytical data set that could be leveraged to derive associations between two SKUs. This analytical data set were further refined to provide ability to identify associations within category and across the categories.
Data Science Experimentation
Three different association mining techniques were evaluated, keeping in mind future scalability for different regions and categories. The winning algorithm was validated out of sample for years 2019 and 2020 till date.
Implementation
Algorithm was released as an end point in AWS, integrated with Tableau for visualization.
The solution
Unified platform to identify cross-sell and up-sell opportunities per SKU
View of product/category and SKU cross-sell options
Cross-sell Associations
The solution shows product category level associations and SKU level associations that are across categories. These associations are useful in identifying cross-sell. For example, how certain industrial sewing machines are associated with certain type of fax machines and printers, or how certain scanners are associated with certain type of personal printers.
Up-Sell Associations
The solution shows the base products and its within category associations to a premier product. These associations help up-sell with higher probability of lift could be positioned. For example, standard yield ink could be up-sold to high yield ink, or single cartridge pack could be up-sold to 3 cartridge pack, or regular paper could be up-sold to premium type paper.

Auto Refresh
Data Bricks is the main processing engine, with jobs scheduled for daily data refresh and AWS end point call to rescore the associations. Output is made available to Tableau post daily refresh. Tableau automatically refreshes the data in the dashboards through a daily scheduler.
Activation Enablement
On-boarding or category management team through dashboard training for designing cross-sell offers and bundles for marketing campaigns.
