Computer-based training allows trainees to work at their own learning pace and style, both of which can be adjusted to match the individual needs of each trainee. The immediate interactive feedback of the computer based training system allows trainees to review sections of the material as frequently as needed. Apart from initial setup costs, computer-based training can significantly reduce overall training costs and training time needed per employee. As managers change and improve the learning materials, the CBT system can be updated once and it can be automatically propagated to all existing trainees at once.
