The influence of information systems on the integration of humanitarian supply chains' performance management in light of disaster preparedness

Humanitarian supply chains (HSCs) play an essential role in alleviating humanitarian crises in disaster-prone settings where lead-time effectiveness is critical. Information systems are key to the integration between humanitarian organizations (HOs) and donors, particularly for performance management that supports preparedness. However, empirical research on how information systems influence such integration remains limited. This study addresses this gap using a mixed-methods approach that operationalizes information systems as characteristics, capabilities, and flows, and links them to the integration between HOs and donors in performance management during preparedness. The methodology consists of a three-phase mixed-methods approach, including survey pretesting through focus group discussions, a survey of 145 Indonesian HOs operating in disaster-prone settings, and focus group discussions to validate the interpretation of the quantitative results. Hierarchical regression analysis reveals that information systems characteristics and capabilities significantly influence integration, and information systems flow can influence integration when challenges are addressed. Theoretically, the study advances understanding of how information systems enable integration for preparedness. In practice, it highlights the need to standardize data formats, define performance metrics and communication protocols, and implement training initiatives. The findings offer insights that strengthen HSC preparedness in similar settings and suggest topics for future research. • A study combined focus groups and a survey of 145 humanitarian organizations. • Information systems improve HO-donor integration in performance management. • The impact of information systems flow is limited without addressing challenges. • Standardization and training should be conducted in disaster preparedness. • Empirical evidence enriches theories and practices of humanitarian supply chains.
