On the surface, design practices and data science may not seem like obvious partners. But these disciplines actually work toward the same goal, helping designers and product managers understand users so they can craft elegant digital experiences. While data can enhance design, design can bring deeper meaning to data.
This practical guide shows you how to conduct data-driven A/B testing for making design decisions on everything from small tweaks to large-scale UX concepts. Complete with real-world examples, this book shows you how to make data-driven design part of your product design workflow.
Understand the relationship between data, business, and design
Get a firm grounding in data, data types, and components of A/B testing
Use an experimentation framework to define opportunities, formulate hypotheses, and test different options
Create hypotheses that connect to key metrics and business goals
Design proposed solutions for hypotheses that are most promising
Interpret the results of an A/B test and determine your next move

The Lean UX approach to interaction design is tailor-made for today's web-driven reality. In this insightful book, leading advocate Jeff Gothelf teaches you valuable Lean UX principles, tactics, and techniques from the ground up - how to rapidly experiment with design ideas, validate them with real users, and continually adjust your design based on what you learn. Inspired by Lean and Agile development theories, Lean UX lets you focus on the actual experience being designed, rather than deliverables. This book shows you how to collaborate closely with other members of the product team, and gather feedback early and often. You'll learn how to drive the design in short, iterative cycles to assess what works best for the business and the user. Lean UX shows you how to make this change - for the better. Frame a vision of the problem you're solving and focus your team on the right outcomes Bring the designers' toolkit to the rest of your product team Share your insights with your team much earlier in the process Create Minimum Viable Products to determine which ideas are valid Incorporate the voice of the customer throughout the project cycle Make your team more productive: combine Lean UX with Agile's Scrum framework Understand the organizational shifts necessary to integrate Lean UX
