Describe the concept of job enrichment. How does job enrichment differ from other job design strategies of job enlargement or job rotation?

Job enrichment is the practice of enhancing job content by building into it more motivating factors such as responsibility, achievement, recognition, and personal growth. This job design strategy differs markedly from job enlargement and job rotation in that it enhances job content by adding duties -- such as planning and evaluating -- that would otherwise be reserved for managers. In contrast, job enlargement and job rotation focus on expanding the number of tasks a person performs, but all the tasks are at the same level of responsibility.
