Abstract: Background: Defining valid workload components and activity standards is a prerequisite for workload-based workforce planning. This study aimed to develop and validate workload components and activity standards for human resources (HR) departments in Iranian public hospitals using a framework aligned with the Workload Indicators of Staffing Need (WISN) methodology. Methods: A consensus-based mixed-method approach was used. An initial list of HR activities was developed through expert consultation and enriched through approximately 200 hours of field observation and staff interviews in a selected public hospital. The resulting workload components and preliminary activity standards were assessed using a structured Delphi questionnaire based on WISN principles. Twenty-three HR and workforce-planning experts participated in two Delphi rounds. Consensus was defined as ≥70% agreement on a five-point Likert scale. Results: At the end of the second round of the Delphi study, 91.6% agreement was achieved. A total of 76 workload components for HR staff were identified and categorized into service, support, and additional activities. The most notable changes from the initial list and the highest level of expert disagreement were related to strategic tasks for the job group, unobservable and cognitive work, repetitive activities, and the allocation of activities in WISN activity categories. Conclusion: The study developed a validated and context-specific set of workload components and activity standards for hospital HR departments. The findings provide a practical foundation for applying the WISN methodology to non-clinical staff and support more accurate workforce planning, organizational redesign, and evidence-based management of human resources in hospitals.
