Organisation size, innovativeness, self-organisation and inter-organisational coordination. International Journal of Emergency Services. DOI 10.1108/IJES-05-2020-002410.1108/IJES-05-2020-0024https://nru.uncst.go.ug/handle/123456789/3924The purpose of this study is to examine how humanitarian organisation size affects inter-organisational coordination and further tested the mediating role of organisational innovativeness, self-organisation in the relationship between humanitarian organisation size and inter-organisational coordination among humanitarian organisations in Uganda. Design/methodology/approach – The study is based on cross-sectional survey; data was collected from 101 humanitarian organisations. The analysis of the proposed hypotheses was done with the help of PLS-SEM using SmartPLS version 3.3.0 for professionals. Findings – The results show that humanitarian organisation size significantly relates with inter-organisational coordination. In addition, self-organisation and organisational innovativeness play a complementary role between humanitarian organisation size and inter-organisational coordination. Research limitations/implications – The findings of this research provide useful insights into the role of humanitarian organisation size in boosting inter-organisational coordination in humanitarian relief delivery. High levels of self-organisation and organisational innovativeness not only improve inter-organisational coordination in humanitarian relief delivery but also enhance the transformation of humanitarian organisation size benefits into inter-organisational coordination. Originality/value – This research is one of the few studies that investigated the effect of humanitarian organisation size and inter-organisational coordination. It also brings into the limelight the mediating role of self-organisation and organisational innovativeness between humanitarian organisation size and inter-organisational ordination in humanitarian relief delivery.enHumanitarian organisationHumanitarian organisation sizeSelf-organisationHumanitarian relief deliveryOrganisational innovativenessInter-organisational coordinationArticle
