Supply Chain Integration Scale

Supply Chain Integration (SCI) refers to an organization's capacity to seamlessly coordinate and align processes, information, and incentives across internal functions and with external suppliers and customers. Flynn et al. (2010) operationalized SCI into three complementary dimensions in the Journal of Operations Management: internal integration (coordination across departments), supplier integration (collaboration with upstream partners), and customer integration (collaboration with downstream partners). Organizations with high SCI reduce costs through process alignment, improve quality through shared information, and accelerate time-to-market through coordinated innovation. This scale has become foundational in supply chain management research and practice.
