This qualitative study delves into Incident Command System (ICS) training dynamics and its efficacy in enhancing collaborative efforts between non-governmental organizations (NGOs) and government agencies during emergency response operations. Anchored in a post-positivist paradigm, the research uncovers the complexities and variabilities of human and organizational behavior in crises through an in-depth thematic analysis of interviews with seasoned emergency response professionals. The analysis illuminates the pivotal role of communication, training, and collaborative strategies in enabling the effective integration of NGOs into emergency responses. It sheds light on the challenges of emergency management collaboration, particularly the issues of miscommunication, the need for a shared operational language, and the transformative potential of ICS training to address these issues. Research findings underscore the necessity for ICS training programs that are customized and adaptable to the diverse needs and operational contexts of NGOs. Structured collaboration and communication strategies are highlight for emergency professionals who navigate the complexities of varied operational languages and protocols. The study advocates a holistic approach to integrating NGOs into ICS-driven emergency responses, promoting cross-cultural communication, leadership across organizational boundaries, and responsive management strategies. It emphasizes the importance of specialized training and sophisticated communication strategies within a comprehensive collaborative framework to enhance NGO contributions to emergency responses. Recommendations include establishing an iterative learning and development cycle to refine collaboration mechanisms and continually, fostering ongoing dialogue and engagement between NGOs and government agencies. The study also identifies the need for adaptable emergency response frameworks, signaling the continuous need for research, improvement, and adaptation. By paving the way for practical applications, the research suggests longitudinal analyses to assess the long-term impact of ICS training, cross-jurisdictional comparisons to understand implementation benefits widely, and the development of training modules tailored specifically to the needs of NGOs. Additionally, the study points to the exploration of technology and digital communication tools as means to modernize emergency response infrastructures, contributing to a more resilient and collaborative national emergency response system.
