My prevailing thinking on why high-tech products succeed or fail boils down to four criteria. Editor’s Note 2/8/2014: I expanded the number to eight and wrote book about them: The Principles of Disruptive Design.
A product must:
- Build on the familiar
- Do what it’s supposed to do really well
- Allow people to do something they wished they could do
- When displacing something else, offer significantly better experience
