In both architectural design and UX design, the hypothesis is that a user has an end goal in mind. For both the architect and the UX designer, their job is to design an enjoyable experience for the user while keeping business objectives in mind.
A simple journey getting from Point A to Point B needs to be balanced with understated exposure to other possible routes. For example:
A family of five drives to a commercial shopping mall on a Sunday to buy groceries at the supermarket for the week. Dad is driving. He follows the signage to the parking garage. He notes the nearest lift lobby to the supermarket and finds a parking lot near it. He knows that a lot is open because the parking lot status indicator is shining green. Mom wheels the stroller up the ramp to the lobby and little Lucy presses the elevator button, which is designed to be at a universally friendly height. The family takes the elevator up to the third floor where the supermarket is.
