Transactional Analysis (T.A):

An OD technique used as a means of improving relationships between individuals. Attempt is made to analyze the social interchange (transaction) among people with the objective of understanding and eventually improving interpersonal relations. When a person through transactional analysis learns to perceive his state or that of others, relations can be better understood and the transaction improved.

As an OD technique, transaction analysis encourages organizational members to act more as adults and less as children or parents, thus making them more receptive to change and capable of responding in a mature manner.
