It’s amazing how even the brightest ray of sunlight can ruin months of work. Several years ago I was part of an industry team working on developing a set of standards for a defined group of symbols and colors to be used in the way that automotive service information was to delivered. We worked diligently for several months to come up with the right experience. Then we built a prototype and showed it to several service technicians who all liked what we had done.
Then we visited one technician to proudly show of our work, but he didn’t want to meet us in his office. He wanted to use the prototype in a real-life scenario. Outside, next to a big greasy machine! It was all going well until the sun came out from behind a cloud, hit the laptop screen and promptly made everything we had done unreadable; the color palette we had selected washed out and everything looked the same. Back to square one on designing the experience!
