Data uncertainty assessment and information flow analysis for product-service systems in a library case study

The provision of service is increasingly becoming a key driver for delivering customer value. This emphasis on service provision is promoted by approaches such as Product-Service Systems (PSSs) that deliver value in use based on integrated products and services. However, to achieve effective delivery of services, it is important to manage information flow and data uncertainty associated with information requirement. The paper proposes a methodology that consists of: (a) the assessment of data uncertainty through the numeral, unit, spread, assessment and pedigree approach and a pedigree matrix consisting of data uncertainties to be scored based on their influence on the system; and (b) the analysis of information flow by means of data flow diagrams that depict information exchanges and an info-dynamic engine that measures the efficiency and recommends improvements for information flows in PSSs. A library case study was undertaken to show how such a methodology can be applied.
