“The deepest form of understanding another person is empathy…[which] involves a
shift from…observing how you seem on the outside, to…imagining what it feels like to be you on the inside.”
Difficult Conversations by Douglas Stone, Bruce Patton, and Sheila Heen of the Harvard Negotiation Project, Chapter 9, “Empathy is a Journey, Not a Destination,” p. 183.
Designing something requires that you completely understand what a person wants to get done. Empathy with a person is distinct from studying how a person uses something. Empathy extends to knowing what the person wants to accomplish regardless of whether she has or is aware of the thing you are designing. You need to know the person’s goals and what procedure and philosophy she follows to accomplish them.
