The document discusses three types of training for developing human resources: learning, training, and development. Learning involves acquiring new knowledge and skills, especially hands-on skills. Training strengthens existing knowledge and skills through re-education, especially hands-on skills. Development refers to building and improving attitudes, abilities, values and beliefs over time, especially for managers, and can be seen as transformational learning. While knowledge and skills can grow quickly through learning and training in the short term, building and improving attitudes, abilities, values and beliefs takes much longer time, even fundamentally without progress.
