This study explores the implementation and adoption of emergency information systems across various government agencies, applying the Diffusion of Innovations (DOI) model to assess the public value generated by these technologies. A comprehensive analysis of several projects was conducted to reveal the factors driving the successful adoption and sustained use of innovative technologies in crisis management. The findings indicated that organisations consistently retained these systems beyond the initial emergency phase, signifying their successful diffusion and integration. Agencies reported high confidence in the new systems, citing their effectiveness in meeting critical needs and addressing challenges during crises. The study identified key factors that facilitated successful diffusion, including perceived relative advantage, compatibility with organisational processes, ease of use, and observable stakeholder benefits. Additionally, the research examined multiple dimensions of public value creation, such as enhanced operational efficiency, improved decision-making, greater transparency, and strengthened inter-agency collaboration. By highlighting the significant public value generated by these systems, the study contributes important insights to the growing literature on technology adoption in public sector crisis management and underscores the potential for innovative systems to deliver lasting impacts beyond immediate emergency response.
