For people who are from the design or innovation field I often describe a Service Blueprint like this:

A service blueprint is a detailed visual representation of the various elements and interactions involved in delivering a service to customers. It is a tool used to analyze and improve the efficiency and effectiveness of a service, as well as to identify potential problems and areas for improvement.

A service blueprint typically includes a detailed flow chart of the various steps involved in delivering a service, as well as a description of the various interactions that occur between the service provider and the customer at each stage. It may also include information about the physical environment in which the service is delivered, the resources and tools needed to deliver the service, and the roles and responsibilities of the various service providers and customers involved.

Service blueprints are used in a variety of industries, including healthcare, hospitality, retail, and financial services, to help organizations understand and optimize the customer experience and improve the quality of their services.

You can find all the Service Blueprint resources I've created here. This includes courses, templates and a library of external links and resources.
