Human resource development (HRD) involves helping employees acquire new skills and abilities needed for their current or future roles through processes like training, feedback, and career development. It also aims to develop organizational culture with strong collaboration. HRD components include manpower planning, recruitment, training, performance appraisal, and career development. An effective HRD climate is characterized by open communication, trust, risk-taking, and supportive policies and mechanisms like performance appraisal and training. Top management support, line manager commitment, and an OCTAPACE culture of openness, trust and collaboration are key enabling factors for HRD.
