These books have helped me, my clients and my employees throughout my career and are highly recommended no matter what position you hold. Whether you’re a HR director, a training manager, an instructional designer, a trainer or a training consultant they will show you many ways on how to manage training efficiently at every levels. Two of those books are from one of my former trainer Harold D. Stolovitch and are highly praised throughout the world. He’s the first one who introduced me to the competence approach which I still apply today after 32 years.
