Data Science and Design: A Tale of Two Tribes
Summary
In this talk, Jon explores the often misunderstood relationship between data scientists and designers and how their collaboration can create significant customer value. Drawing on his experience at Intuit, he discusses developing an enterprise-wide A/B testing platform that initially struggled with adoption until working closely with designers to identify key leading metrics like platform ease of use and time to deployment, rather than just lagging outcomes. Jon also recounts a retail case where overwhelming daily data was distilled by studying top-performing store managers in context, enabling the team to design a focused dashboard that increased sales conversion by 10%. Lastly, he highlights eBay's approach to extracting meaningful signals from vast transaction data by partnering designers with 300 data analysts to streamline workflows and reduce insight time from weeks to a day, democratizing access across the company. He concludes that integrating data science fully into product teams alongside design and development creates more delightful, insight-driven products.
Key Insights
-
•
Less than 1% of global data is used to generate human insights, showing the value in efficient data utilization.
-
•
A data scientist combines statistical skills, hacking mindset, and entrepreneurial thinking to solve complex problems.
-
•
At Intuit, pairing designers with data scientists uncovered that ease of use and awareness were key to increasing adoption of an A/B testing platform.
-
•
Lagging indicators like number of experiments performed or features deployed are insufficient alone; leading indicators such as time to consumption and user awareness better drive adoption.
-
•
Ethnographic studies can reveal user behaviors and misalignments in what enterprise teams measure versus what actually drives business outcomes.
-
•
Studying the best-performing store leaders on the floor uncovered critical behaviors that informed a focused dashboard replacing overwhelming 424-page daily reports.

•
A simple data product tracking live customer-to-employee ratios, transaction progress, staff availability, and service queue length helped retail store managers improve performance and customer experience.
-
•
eBay’s approach to ‘signal extraction’ from massive data involves time series analysis, decision trees, and close designer-analyst collaboration to cut insight delivery from weeks to a day.
