The following are rather common myths, or misunderstandings, among new supervisors, particularly if they don't understand the basics of good training and development. It's hard to accept that any job will stay the same all the time with today's increasing competition and the increasing demands of their customers. Besides, because someone was hired doesn't mean they have the best knowledge and skills to do the best job for the company.
Every job is unique.
The job is being carried out in one company in one location at one time with unique people. Because a job is unique does not mean that the company should never seek help elsewhere. Unless an employee is performing a highly routine task on a highly customized machine, the trainer or consultant doesn't have to know exactly what a job entails and all about who is carrying out the job. The point of training and development is to work with learners to develop new knowledge and skills. Highly effective training includes teaching the learner how to learn, including how to come up with new ideas and approaches.
