Compare and contrast job enrichment with job enlargement

What will be an ideal response?

Answer: The strategy behind job enrichment is to make jobs more challenging and interesting by expanding the range of skills required–typically by expanding upward, giving employees some of the responsibilities previously held by their managers. For example, an employee who had been preparing presentations for his or her boss to give to customers could be asked to give the presentations as well.
Whereas job enrichment expands vertically, job enlargement is more of a horizontal expansion, adding tasks that aren't necessarily any more challenging. If it simply gives workers more to do, job enlargement won't do much to motivate and will more likely demotivate. However, if jobs are enlarged in ways that increase worker knowledge, expansion can improve job satisfaction.
