JCM proposed that any job may be described by five core job dimensions. Skill variety is the degree to which the job requires a variety of different activities, so the worker can use a number of different skills and talent. Task identify is he degree to which the job requires completion of a whole and identifiable piece of work. Task significance is the degree to which the job has a substantial impact on the lives or work of other people. Autonomy is the degree to which the job provides substantial freedom, independence, and discretion to the individual in scheduling the work and determining the procedures to be used in carrying it out. And, feedback is the degree to which carrying out the work activities required by the job results in the individual obtaining direct and clear information about the effectiveness of his or her performance. The first three dimensions—skill variety, task identity, and task significance—combine to create meaningful work the incumbent will view as important, valuable, and worthwhile. From a motivational standpoint, the JCM proposes that individuals obtain internal rewards when they learn (knowledge of results) that they personally (experienced responsibility) have performed well on a task they care about (experienced meaningfulness). Individuals with a high growth need are more likely to experience the critical psychological states when their jobs are enriched—and respond to them more positively—than are their counterparts with low growth need.
