Abstract:
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.
