2. Map the Physical Evidence of Service:
Everyone should be able to see the service process and the existing elements of physical evidence. An effective way to depict service evidence is through the service map, or blueprint. From the map one can read the actions involved in service delivery, the complexity of the process, the points of human interaction that provide evidence opportunities, and the tangible representations present at each step. To make the map even more useful, photographs or videotape of the process can be added to develop a photographic blueprint.
