工作需求分析（JDA）

Job Demands Analysis (JDA) is a methodology applicable across diverse sectors including healthcare, manufacturing, and logistics, often employed during the design or redesign phase of job roles to ensure optimal alignment between employee capabilities and job requirements. In healthcare, for instance, JDA can assess the physical demands placed on nurses who need to lift patients, while in manufacturing, it can analyze cognitive loads on assembly line workers to optimize task assignments and workflow. Participants typically include occupational health specialists, ergonomists, human resource personnel, and frontline employees, who contribute valuable perspectives on job functionalities and challenges. The data gathered through various methods like observations and interviews inform organizational strategies for effective worker placement and help in the design of comprehensive return-to-work programs following injuries or illnesses. By identifying potential hazards, JDA contributes significantly to improving workplace safety and enhancing job satisfaction through better role fit. This flexibility in application makes JDA suitable for any phase where job reevaluation is necessary, enabling organizations to adapt to changes in technology, workforce dynamics, or regulatory requirements.
