Symbols and Customer Performance

While doing some research today on totally unrelated tasks, I stumbled upon a 1967 article from the journal Science. It is by two gentlemen, Charles Baldwin and Robert Runkle, and describes their development of the biohazard symbol. The symbol was the product of an obvious customer performance problem, keeping humans safe from biological health hazards.

From the perspective of the coproduction experience model, symbols like this would be best classified as Access:Information, as they aid customers in making decision about products and environmental spaces.
