This document discusses the importance of training for fieldbus technology. It notes that training all project team members, including engineers, maintenance staff, operations staff, and sales/support personnel is critical for project success. The document emphasizes that customers are asking more sophisticated questions, so suppliers need to provide the right answers. It also stresses that change is difficult for those who are surprised by it, and that fieldbus implementation represents significant change from previous automation technologies. Therefore, training is presented as key to helping people learn new aspects of fieldbus and unlearn old ways that are no longer applicable.
