I was at a tournament over the weekend. For each of the age groups, there were two flights -blue and white. I walked past the scores posting boards and the obvious leapt right out at me. One board that held the blue flight scores was blue; the other was, you guessed it, white.
It was a simple thing, but an incredibly obvious solution to getting the right people to the right board quickly. Instead of all the score sheets posted together, the tournament thought about how teams perceived scores reporting and made it easier for THEM. A little thing that made a big difference.
