Problems arise when people get older, but that just means opportunities for better design to support older users. The very best designs will help older users, but also be adapted by everybody else.
To solve big-scale design problems, Don Norman recommends engaging with the community that has these problems and leveraging existing creativity and experience.
Human-centered design has 4 principles: understand the problem, the people, and the system, and do iterative design. But what if you don't have time to do all 4 steps?
Human-Centered Design (HCD) is not about following processes. It’s about being mindful of HCD principles. Keep focus on people and the entire system to solve the right problems.
