• Stank, Keller and Daugherty (2001) conducted a multi-industry analysis to study
the relationship between integration and performance, while we consider the
integration process of companies that belong to the same industry. Other
differences between this study and ours are: first, they consider a unique level
of internal integration, while we compare the integration achieved in two internal
interfaces (Logistics-Marketing and Logistics-Production). And, second, they
consider a unique level of external integration for each firm, while we consider
that the level of external integration has to be related to a particular relationship
(of the firm) and not to the firm itself.
