Training and development aims to improve employee performance by increasing abilities through learning and changing attitudes or skills. It provides several organizational benefits such as increased efficiency, morale, and relations while reducing supervision needs. Training programs follow a strategic model with four phases: needs assessment, design, implementation, and evaluation. The needs assessment phase involves analyzing the organization, tasks, and individual employees. The design phase develops objectives and incorporates learning principles. Implementation uses various methods like on-the-job training. Evaluation assesses reactions, learning, behavior, and results. The overall goal is suitable individual change related to organizational demands.
