The DURF Pyramid

This image is Figure 7.1 from my book The Lean Product Playbook. I nicknamed the pyramid the “DURF” pyramid after one of my clients who wanted to save time just wrote the letters D, U, R and F in the 4 layers. I adapted this figure from a figure that Jussi Pasanen adapted from Aaron Walter’s book Designing for Emotion.
