The implementation of “Industry 4.0” in the manufacturing sector and related branches is bringing considerable changes in its wake. Skilled workers will be massively affected by this. In order to clarify the need for change, a study of all metal working and electrical occupations including IT occupations in the manufacturing sector was undertaken on behalf of the Bavarian Employers’ Associations for the Metalworking and Electrical Industries (bayme vbm). This involved comparing the occupational profile positions of the respective training occupations with changes identified and the requirements derived from such changes. This procedure is described in the article and illustrated by using the occupation of mechatronics fitter as an example.
