Analysis of the factors affecting real-world value stream performance

This paper describes the procedures adopted for auditing 32 value streams covering a range of market sectors. To establish a baseline for comparing audit results, the uncertainty scores have been estimated for Our Value-added Process; Our Supply Side; Our Demand Side; and Our Control System sources. These are ranked according to a composite uncertainty measure. 'Exemplars' resulting from this ranking have a number of common and transferable best practices. A subsequent statistical analysis investigates the importance of 15-customer interface; supplier interface; and product characteristics arising from proposals put forward in the SCM literature. Six of these parameters are statistically significant for this sample. Our statistical analysis therefore supports their adoption in supply chain design.
