Job design is the process of linking specific tasks to jobs and determining the methods required to achieve organizational objectives, considering factors like employee abilities, task characteristics, and work practices. Approaches to job design include job enlargement, job enrichment, job rotation, and designing for efficiency, motivation, and safety, aiming to boost job satisfaction and performance. The Job Characteristics Model identifies critical components that enhance intrinsic motivation, focusing on skill variety, task identity, task significance, autonomy, and feedback.
