1. Using the job characteristics model as a guide from below, discuss how a manager can enrich or enlarge employees' jobs.

Skill variety: The extent to which a job requires that an employee use a wide range of different skills, abilities, or knowledge. Example: The skill variety required by the job of a research scientist is higher than that called for by the job of a Wendy's food server.

Task identity: The extent to which a job requires that a worker perform all the tasks necessary to complete the job, from the beginning to the end of the production process. Example: A craftsworker who takes a piece of wood and transforms it into a custom-made desk has higher task identity than does a worker who performs only one of the numerous operations required to assemble a flat-screen TV.

Task significance: The degree to which a worker feels his or her job is meaningful because of its effect on people inside the organization, such as coworkers, or on people outside the organization, such as customers. Example: A teacher who sees the effect of his or her efforts in a well-educated and well-adjusted student enjoys high task significance compared to a dishwasher who monotonously washes dishes as they come into the kitchen.

Autonomy: The degree to which a job gives an employee the freedom and discretion needed to schedule different tasks and decide how to carry them out. Example: Salespeople who have to plan their schedules and decide how to allocate their time among different customers have relatively high autonomy compared to assembly-line workers, whose actions are determined by the speed of the production line.

Feedback: The extent to which actually doing a job provides a worker with clear and direct information about how well he or she has performed the job. Example: An air traffic controller whose mistakes may result in a midair collision receives immediate feedback on job performance; a person who compiles statistics for a marketing research firm often has little idea of when he makes a mistake or does a particularly good job.
