With training in the office, however, we think that one big burst is enough. It is not. Ongoing training is the only way to achieve that goal. Classroom training for children is conducted in one hour chunks. That is not an accident.
People learn better in small bites.
Adults want to take their training and put it to use immediately. Then tell them what you told them. As in any kind of training, reinforcement enforces learning. Spring for lunch, and train your staff in small groups, around a conference room table. These seminars can be developed by someone on your staff or can be developed by an outside consultant.
