The hierarchy of needs is a theory in psychology proposed by Abraham Maslow
describing the stages of growth in humans. But just like in humans,
interfaces go through different stages of growth too. These stages of
growth for interfaces are the user experience hierarchy of needs.
The most basic needs start at the bottom of the pyramid and end with
the highest needs at the top. If the basic needs aren’t met, it’s
difficult to find the desire and motivation to meet the higher
needs. The basic needs in the UX pyramid are functionality and
information. The higher needs are aesthetics and usability.
