In data-driven design, data is at the center of the design decisions. It’s the primary (and sometimes, the only) input. Data-driven design looks to ship fast, optimize at every step and let the data drive many of the design decisions.
In data-informed design, data is a key input among many other variables. You use the data to build a deeper understanding of what value you are providing to the users. You combine data with qualitative feedback and your design intuition to produce iterations of successful products. Your expertise and understanding of information plays as great a role in your decisions as the information itself.
Good product design comes from striking the right balance between data, empathy and intuition.
What you can do:
“Data and A/B test are valuable allies, and they help us understand and grow and optimize, but they’re not a replacement for clear-headed, strong decision-making. Don’t become dependent on their allure. Sometimes, a little instinct goes a long way.” - Julie Zhuo, VP of Product Design at Facebook
