Which characteristic is NOT part of the job characteristics model?

In the context of the job characteristics model, task diversity is not one of the defining characteristics. The job characteristics model, developed by Hackman and Oldham, identifies five core job dimensions that significantly impact employee motivation and satisfaction. These dimensions include skill variety, which refers to the extent to which a job requires a range of different activities; task significance, which highlights the importance of the job and its impact on others; and task feedback, which involves the information employees receive about their performance.

Task diversity, while it may imply a variation in tasks, is not specifically included as a characteristic that affects job motivation in the model. Instead, the job characteristics model emphasizes the importance of the specific dimensions mentioned to create meaningful work experiences for employees, leading to higher levels of internal motivation, satisfaction, and performance.
