Germs are in the details
I found another one in Coupeville, WA, the other day.
Despite the rather industrial graphics, there’s a few improvements. It’s very clearly for cleaning the cart, not your hands (as Safeway suggested).. It’s right next to the carts, so when you take a cart, you use it (rather than located near the exit, at Safeway). And should the Red Apple employees fail to maintain the display, there’s at least an encouraging reminder to the customer that they should ask to have it replenished.
This is no iPhone, it’s not a radical innovation, but it’s a definite response to a need, and tracking how it is and isn’t being dealt with is enlightening. First, one has to understand the need. Then one has to develop a solution. Then the solution must be implemented. Properly. Effectively. And throw in iteration, for fun. The fact that something as simple as this fails around solution/implementation at a major chain like Safeway tells you something about the organizational barriers to even the most mild of innovations.
