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. Besides, organizations usually have a lot more in common with other organizations then employees realize. If employees need new knowledge or skills, they'll know about it faster than anyone else. Few organizations afford employees the time and guidance to reflect on what they're doing, to learn new ideas and establish new approaches.
Employees are experts at doing their jobs the way that they do their jobs.
If they're doing their jobs inefficiently, they're experts at doing their jobs inefficiently. If employees attended a course, then they learned what the organization needed Courses are not quick fixes. After years of classroom education, most of us automatically think of learning as going to a course. We go down the list of courses in the training catalog, pick the title that seems closest to what we're doing and we sign up for the course. Many supervisors work the same way.
