Academic literature would appear to indicate that supply
chain integration is a major factor in explaining the performance of companies.
The results are nevertheless inconclusive. Certain authors put forward the idea that
the vast range of results obtained are due, amongst other things, to the fact that
there is no exactness to the group of scales used, no-one has yet published an
analysis of the measurement models nor clear benchmarks. In this paper, we present
the theoretical definition of four supply chain integration scales (clients, suppliers,
external and internal) and the convergent and discriminant validity of a
measurement instrument based on a list of items taken from earlier papers. We also
propose a benchmark to interpret the scales by percentiles, using a diverse international
sampling broken down into sub-samples based on sector, type of company,
size of company and degree of vertical integration.Ministerio de Ciencia e Innovación DPI2010-18243Ministerio de Educación y Ciencia DPI2006-0553
