Job enrichment is an attempt to motivate employees by giving them the opportunity to use the range of their abilities. It is an idea that was developed by the American psychologist Frederick Herzberg in the 1950s. It can be contrasted to job enlargement which simply increases the number of tasks without changing the challenge. As such job enrichment has been described as 'vertical loading' of a job, while job enlargement is 'horizontal loading'. An enriched job should ideally contain:
##A range of tasks and challenges of varying difficulties (Physical or Mental)
##A complete unit of work - a meaningful task
##Feedback, encouragement and communication
