사용자 및 전문가 기반 평가를 활용한 재난관리자원 통합관리시스템(KRMS)의 사용성 분석

초록

This study analyzed the usability of the Korea Disaster Management Resource Integrated Management System (KRMS) using combined user- and expert-based evaluations to explain its low utilization in practice. Expert heuristic evaluation assessed effectiveness, efficiency, satisfaction, interface quality, and related factors, and found that none of the items were rated as “met,” with most judged “partially met” or “not met.” Severity ratings indicated that level 2 (moderate problems) accounted for the largest proportion. User evaluation was conducted with disaster management practitioners from a local public enterprise in Seoul, who completed representative task scenarios and the System Usability Scale (SUS). The average SUS score was 24.6, placing KRMS in the “Not Acceptable” range in international benchmarks. Key difficulties included complex procedures, overly segmented menu structures, and low intuitiveness, suggesting that structural and procedural complexity constrains usability in real work contexts and informing future system improvement and policy considerations.
