It is believed that the training courses focus on providing practical skills and knowledge closely related to actual needs. Participants attend training courses in order to gain the professional knowledge needed in a specific field or industry in order to succeed in their work. The training content should be directly available and meet the requirements of the workplace. This can be achieved by combining theoretical teaching with practical case analysis.
