It’s rare, a designer who believes in both aesthetic and strategy (me!)
Often I have to stop myself ‘over-designing’ and pulling design back to its bare bones, with the question - what does the user want to achieve? How can I provide this in its simplest most effective way?
Paper prototyping is perfect for this, getting your thoughts quickly down on paper - great for early stage conceptualising. Its speed, ease, and simplicity, not to mention automatic documentation, make it far better suited for experimenting with new ideas than more complex digital prototypes.
