Information-intensive service (IIS) is a type of service in which information interactions have the most effect on service value creation. Recent innovations of information and communication technology have created various types of IISs, and the literature argues that IIS should be a research priority in this information economy. This research proposes a new service blueprinting framework specialized to IISs, called the Information Service Blueprint. The framework user can succinctly capture the big-picture and key points of the complex IIS process in question by blueprinting an IIS. The Information Service Blueprint has served as a basis for blueprinting IISs in IIS design projects with industry and government. An experiment to compare the Information Service Blueprint with the conventional service blueprint also confirms its utility for blueprinting IISs. This research would serve as a basis for analyzing and designing IISs.
