How do you feel when the success of your design hinges on metrics? For me, I used to not like it. I felt that it was too rigid and that design shouldn’t be reduced to a number game, which I talked about earlier. Since then, I’d been trying to learn the best practices of integrating data into design, and this book Designing with Data — written by Rochelle King, Elizabeth F. Churchill and Caitlin Tan— helped me understand better the role data plays in product design. I’m sure you’ll benefit a lot from this book, just like I did. Below are my learnings.
