Good training helps companies develop happy and productive workers. If organizations are going to spend thousands of dollars on conducting training for their employees and thousands more in lost productivity from taking employees away from their jobs for training, then they need to maximize their return on that considerable investment. Organizations need to make sure they are doing everything they can to ensure that training is useful, that they are using the most modern teaching methods, and that their employees are getting the most out of their class and time away from work. Incorporating useful exercises into the course can accomplish this.
