Which technique involves combining multiple tasks into one job to increase variety?

Job enlargement is a technique that enhances a role by combining multiple tasks into a single job, which increases the variety of work an employee does. This approach aims to reduce monotony by allowing employees to engage in different activities, potentially leading to greater job satisfaction and motivation. By providing a wider range of responsibilities, employees can develop new skills and experience a sense of ownership over their work, which can improve overall performance and morale.

The other techniques mentioned have distinct purposes. Job rotation involves moving employees between different tasks or jobs at regular intervals, enhancing skill development and flexibility but not necessarily increasing the variety of a single job. Job consolidation generally refers to combining roles or responsibilities to streamline operations, which might not enhance variety. Job simplification focuses on reducing the complexity of tasks to increase efficiency, which can lead to a more limited scope of work rather than a richer job experience. Therefore, job enlargement is the most fitting technique for increasing task variety.
