Information sharing in supply chains, myth or reality? A critical analysis of empirical literature

Abstract

Purpose – The purpose of this paper is to investigate what empirical evidence exists regarding benefits of information sharing in supply chains, and to identify potential gaps and opportunities in this research area. Design/methodology/approach – The authors conducted an in-depth, systematic literature review and multilevel analysis of 82 selected articles. In the analysis, the authors investigated: whether the articles applied the supply chain as the unit of analysis; the selected research method; whether the articles applied the supply chain as the unit of data collection (i.e. collected data from three or more different companies); and finally, aspects of information sharing – including benefits. Findings – Despite anecdotal descriptions of benefits from information sharing in supply chains, the authors could not find empirical evidence to support these claims. Rather, the main body of literature reports on a focal company's perspective on traditional buyer-supplier relationships. Research limitations/implications – Given the lack of evidence for the claimed benefits of information sharing on a supply chain level, more research is needed in this field. The authors therefore propose an agenda for future research building on four key points. Originality/value – Contrary to popular belief, empirical evidence for benefits of information sharing in supply chains does not seem to exist. This article highlights an issue previously not addressed with a systematic in-depth review and analysis of empirical articles.
