Design Thinking is a problem-solving method that puts people at the heart of how you think, and asking questions is essential when building user-centered products to minimize guesswork and create experiences from user insight and data. The Design Thinking exercise "Questions and Assumptions" helps teams get all their assumptions out into the open to work through together, making it a great activity to run almost anytime, whether kicking off a project or mid-project to track progress. To run this activity, teams need someone to facilitate, a space to collect questions and assumptions, and a prompt for participants to react to, then gather questions and assumptions asynchronously before prioritizing them on a grid based on risk and certainty levels. By doing so, teams can come to a consensus about what work needs to be tackled first and figure out how to answer or debunk their assumptions, uncovering new insights that can inform product development and improve user experiences.
