Seeing the road ahead — Catseyes and iterative design

Close up of a "catseye" reflective road stud, in the middle of a road

Having previously worked on projects where stakeholders had set a tight timeframe, and not allowed for any testing and iteration of the solution, I wanted to explore the concept of iterative design, and how it can benefit a project. I had learned as a child about the story of Percy Shaw, and how he had devised Catseyes, the reflective studs that illuminate the centre line of a road, inspired by the eyes of an actual cat reflecting his car’s headlights one evening. Using this example, I describe how Shaw didn’t just create his solution from that discovery, but went on to revise his design, test it, and incorporate new ideas until he produced the design that we know today. In the same way, projects can benefit from this approach, getting feedback on their designs, and ensuring that they suit user needs, before they are launched.
