This is a part of lecture presented by Dr. Tripti Vijaywargia, Associate professor of Biyani Girls College. Conflict means disagreement, clash, difference of opinion and variance. Conflict can occur at the individual, interpersonal, group and organizational levels. Conflicts create difficulties in management and the working of organizations and groups. Frustration occurs when a motivated drive is blocked before a person reaches a desired goal. The barrier may be either overt (outward or physical) or covert (inward or mental-socio-psychological). A smooth progression of the need-drive- incentive motivational cycle and fulfillment of one’s expectations do not always occur in reality. There are some difficulties and barriers that do not let a person achieve his goals and so they cause in frustration.
