Effective information sharing is essential for improving the efficiency and effectiveness of supply chains. However, the specific impact of various information sharing factors on mitigating the bullwhip effect has not been extensively investigated in existing literature. This study addresses this gap by systematically reviewing and analyzing research from 2015 to 2024, focusing on how different information sharing factors contribute to bullwhip effect mitigation. We reviewed 57 articles to gain insights into five critical factors: what information is shared, how it is shared, with whom it is shared, why it is shared, and the direction of information sharing. Our analysis indicates that “why to share” and “what to share” are the most frequently studied dimensions, while “how to share,” “with whom to share,” and “the direction of information sharing” have been less explored. This study underscores the need for further research on these less examined factors and enhances understanding of their role in mitigating the bullwhip effect. Additionally, it provides a future research agenda to direct further investigations in this domain.
