Effective plant-specific computer-based training (CBT) used in a formal training program can make the difference between a successful start-up and a failure. Or, in the case of an existing plant, it can make a huge difference in the effectiveness of operating results—particularly if turnover of experienced personnel is a factor. Once the plant process design and control strategies have been established, equipment has been ordered, and the plant is either operating or under construction, the only major variable affecting success is the capability of plant operating personnel. It is essential that the myriad details concerning plant operation are documented in a comprehensive CBT system suitable for training the non-technical personnel who will operate the plant.
