Yayın Divergent metrics: exploring supply chain performance in humanitarian organizations versus public and private sectors(Asos Yayınları, 2024-10-12) Alaff, Monther; Karayaz, Gamze; Aysuna Türkyılmaz, CeydaHumanitarian organizations operate under conditions that require rapid response and flexibility, often in crisis situations where traditional supply chain metrics may not be applicable. Their focus on speed, adaptability, and stakeholder engagement contrasts sharply with the public and private sectors, which typically prioritize efficiency, cost-effectiveness, and long-term strategic planning. This paper investigates the differences in supply chain performance measurement between humanitarian organizations and the public and private sectors, highlighting the unique challenges and objectives that define each domain. Through a thorough literature review, we examine existing frameworks and metrics used in supply chain performance evaluation across these sectors. To achieve this goal, a systematic literature review was conducted, analyzing 57 articles published between 2000 and 2024 across four databases: IEEE Xplore, Web of Science, Scopus, and JSTOR. Our analysis reveals that while public and private sectors benefit from established performance metrics such as ROI and inventory turnover, humanitarian organizations often rely on qualitative measures and emergent indicators that capture the complexities of disaster response. As a result, this research introduces a model for supply chain performance specifically tailored for humanitarian organizations. The model includes the most relevant metrics and attributes to assist both researchers and practitioners in their future work.Yayın Does supply chain integration enhance humanitarian supply chain performance? an empirical investigation of operational outcomes(Işık Üniversitesi Yayınları, 2026-04-29) Alaff, Monther; Karayaz, GamzeHumanitarian supply chains (HSC) operate in high-uncertainty environments where speed and adaptability are critical, yet existing supply chain integration (SCI) models are primarily derived from commercial contexts. This creates a gap in understanding how integration affects performance in crisis operations. This study investigates the effect of SCI on HSC performance, focusing specifically on lead time and flexibility as two core performance dimensions. The research employs explanatory mixedmethod design. Quantitative data were collected through a survey of UN supply chain staff, while qualitative insights were obtained from executive interviews. Five integration constructs: beneficiary, supplier, government, partner, and internal integration, were operationalized and analyzed statistically. The results indicate all constraints significantly influence supply chain performance, yet beneficiary integration shows the strongest effect on both lead time and flexibility, while supplier, government, and partner integrations exert more limited effects. The findings provide a context-specific theory of humanitarian SCI, demonstrating that integration strategies must be tailored to crisis conditions rather than replicated from commercial models.
