There are four stages in the Iterative Cycle of Human-Centered Design. #readingToday

Make observations on the intended target population, generate ideas, produce prototypes and test them. Repeat until satisfied. This is often called the spiral method (rather than the circle depicted here), to emphasize that each iteration through the stages makes progress. 1. Observation 2. Idea generation (ideation) 3. Prototyping 4. Testing
