Lean, Agile & Design Thinking with Jeff Gothelf. There are so many design methodologies available these days — lean, agile & design thinking being the most popular. Could you use them side-by-side? Our guest today is Jeff Gothelf, author of Lean UX and Sense & Respond, and co-founder of Sense & Respond Press. You’ll learn how to make the most out of these frameworks, help teams talk to each other, and measure customer outcomes (instead of your effort) using the right behavior metrics.
