To cope with change and to assume leadership so that an organisation not only reacts to changing scenario but also pro acts, it is necessary that an organisation develops self-renewing capacities. Organisation Development (OD) is an effort to improve organisation performance and organisation functioning. OD is a process that applies behavioural science knowledge and practices to help organisations achieve greater effectiveness, including increased financial performance and improved quality of work life. The course analyses and describes the best approaches to diagnose the structure, styles, skills, systems and other variables of the organisation that affect the conditions and performance of an organisation.
