Which concept increases the scope of a job by adding duties at the same level to increase variety?

• A. Job rotation
• B. Hygiene or maintenance factors (Herzberg's)
• C. Maslow's hierarchy of needs
• D. Job enlargement

Answer: (D)

Adding duties at the same level to give more variety is job enlargement. This horizontal expansion means the role includes more tasks without moving the worker up to a higher level of responsibility, so the job feels broader and more varied. It’s different from job rotation, which changes the tasks you do by moving you to different roles rather than simply adding more tasks to the same role. It also isn’t about motivator factors in Maslow or Herzberg’s hygiene factors; those theories relate to needs and satisfaction, not expanding the job’s scope.
