Know How: The Definitive Book for Occasional Trainers, Content Experts, Educators, Mentors, Coaches, and Even Parents, by Harold D. Stolovitch and Erica J. Keeps, is for people with the know-how that someone else requires. It is written for those who need to transfer knowledge to others: subject matter experts, proficient performers, managers, coaches, co-workers, and even parents. Learning and development professionals are experts in many areas, and we often feel driven to transform what we have learned about training and learning into a useful tool that anyone can readily access and apply. Learning the best methods and practices for transferring our knowledge to those who need it is critical for us and for our trainees to be successful.
