HRD training programs are specialised types of advanced or specific business courses. They are focused on the development of human resources within an organisation, including communication skills, leadership styles, and team relationships. Some organisations choose to include their employees in these programs because it is known that increased human capital can increase organisational profits over time due to improved productivity and reduced turnover rates among workers which are costly businesses. Participants in these HRD programs often leave feeling confident about themselves as a leader, learner, team member, conversationalist with colleagues and superiors alike.
