Describe the core characteristics model of job enrichment. Explain how this model can provide guidance to practising managers.

The core characteristics model offers a diagnostic approach to job enrichment and offer a way for managers to create enriched or unenriched jobs that best fit the needs of people and the organisation. The five core characteristics are skill variety, task identity, task significance, autonomy and feedback from the job itself. According to the model, job satisfaction and performance are influenced by the critical psychological states of the individual's experienced meaningfulness of work, experienced responsibility for the outcomes of work and knowledge of actual results of work activities. Employee growth-need strength, knowledge and skill, and contextual satisfaction are important moderator variables in the job characteristics model. Forming natural units of work, combining tasks and practising vertical loading are ways for improving the core job characteristics. The model can provide guidance to managers on how to create high internal work motivation, high growth satisfaction, high general job satisfaction and high work effectiveness.
