Human needs fundamentally don’t change. The ways we address them do.
Consider this: we’re still improving the way we get from Point A to Point B. Yesterday’s horse-drawn carriage was a prototype for today’s automobile. Today’s automobile is just another prototype for tomorrow’s transportation breakthrough.
The problem is defined by a fundamental human need: getting from A to B. The solution at any point in time is situated in the constraints and affordances of the era: technological advancements, evolving resources, changing consumer expectations.
Being essential to your users and clients over time is about engaging in a continuous conversation with them through the solutions you offer. As you iterate on the next generation of offerings, stay true to the fundamental human need you’re solving, and stay in touch with the evolving context it inhabits.
