This thesis investigated how managers are involved in the training process for new employees and how managers can contribute to decreasing of human errors, which enhance quality. This was done by preforming a single case study at a vehicle manufacturer in Sweden where interviews were used as data. The sample for the interviews were managers from the case company that were involved during the training process.  A thematical analysis approach were used to analysis the data from the conducted interviews. The findings identified six different themes; Comprehension, communication, experience, responsibility, supporting and view of quality. Out of these themes the managers only impact on four of them, comprehension, communication, experience and responsibility, in the training process to enhance quality. The thesis also provided what contributions quality improvements had to sustainability.

Further research should be conducted with a similar research design but in other contexts to see if similar findings can be identified. It should also examine the training process from new employees’ perspectives.
