The blueprint is an operational tool that describes the nature and the characteristics of the service interaction in enough detail to verify, implement and maintain it. It is based on a graphical technique that displays the process functions above and below the line of visibility to the customer: all the touchpoints and the back-stage processes are documented and aligned to the user experience.
