Design for Extremes: Aim at the Edge, and the Middle Comes Free

Definition

Design for Extremes

A design approach that ensures products work well for users at the 2.5th and 97.5th percentiles, covering the smallest to largest range of users.

Design for extremes deliberately targets the user with the greatest need, drawing on the physical, sensory and cognitive limitations set out in C1.2.1.
It inverts the usual instinct, because instead of asking who most of my users are, the designer asks who will struggle most with this.
Solve the problem for that user, and the result is almost always easier for everyone else too.
The reverse does not hold, because a design built around the average user routinely fails at the edges, so you cannot start in the middle and patch the extremes on afterwards.
