Fayol presented work specialization as the best way to use the human resources of the organization.

During this period Guanajuato developed an organization and work specialization in governing centers.

Work specialization (also called division of labour or job specialization) is the degree to which organizational tasks are sub-divided into individual jobs.

This enabled him to test his original hypothesis, which was that an increase in work specialization and the division of labour is linked to the change from mechanical to organic solidarity.

Both Dr York and Dr Itzhaky teach in the School of Social Work at Bar-Ilan University, where they are in charge of the community work specialization.
