Final answer:
Job enlargement involves increasing the variety of tasks within a job, while job enrichment focuses on increasing the depth and complexity of tasks. Both aim to increase job satisfaction and motivation.
Step-by-step explanation:
Qualitatively extending the range of activities performed by a job refers to the concepts of job enlargement and job enrichment. Job enlargement involves increasing the variety of tasks and responsibilities within a job, while job enrichment focuses on increasing the depth and complexity of the tasks involved.
For example, in job enlargement, a cashier may be assigned additional tasks such as restocking shelves or handling customer inquiries, in addition to their regular cashier duties. On the other hand, job enrichment may involve giving the cashier more decision-making authority, allowing them to handle customer complaints and resolve issues.
Both job enlargement and job enrichment aim to increase job satisfaction and motivation by providing employees with more challenging and rewarding work experiences.
