Background: Nowadays, humanitarian relief organizations are more and more present in people’s lives due to the number of recorded natural disasters increasing over the last 30 years. Although there are several actors involved in humanitarian aid, the need to integrate logistics service providers into humanitarian relief operations has been recognized. Howev- er, the literature lacks particular attention concerning the coordination roles and objectives between humanitarian relief organizations and LSPs during disaster relief operations.

Purpose: The purpose of this study is to explore the relationship between UNICEF and its LSP(s) during disaster relief operations. More specifically, this study aims to understand the elements that drive, facilitate, constrain and affect the relationship UNICEF has with its LSPs.

Method: A qualitative, exploratory research approach was used, using a real-context case study as the research design. The empirical data was collected through in-depth semi- structured interviews with four respondents representing both UNICEF and its LSPs.

Conclusion: The researchers present a revised version of the conceptual framework used to conduct this research. One additional component was added to the list of compo- nents affecting the effectiveness of a relationship. In addition, some other influencers were discussed. This conceptual framework can be used to formulate an effective relationship between two humanitarian actors within disaster relief operations. Finally, forming a rela- tionship between UNICEF and its LSPs is nothing new. Recommendations for future re- search include investigating implementation efforts once a relationship is built, in order to improve disaster relief operations and save more lives.
