How do you provide meaningful insights that lead to action? When designing a UI, we need to consider what data to display, how to display it in a way that helps users interpret its meaning, and how best to indicate what can be done based on the data and its meaning. Good design can help users quickly grasp a situation, make better decisions, and take productive actions. We will provide a framework that describes a progressive evolution of data displays and actions, and share a broad range of examples, from consumer products to enterprise web applications, to discuss ways to design effective data displays and integrate actions.
