The IDEO method cards are divided into four "suits", drawing on their playing card metaphor. They are defined as:

• Learn: Analyze the information you've collected to identify patterns and insights
• Look: Observe people to discover what they do rather than what they say they do
• Ask:Enlist people's participation to elicit information relevant to your project
• Try:Create simulations to help empathize with people and to evaluation proposed designs
