The document discusses the MARS model of individual behavior and performance. The MARS model proposes that an individual's behavior and performance is determined by four main factors: Motivation, Abilities, Role Perception, and Situational Factors. Each of these factors is then defined in more detail, with Motivation described as the internal forces that direct behavior, Abilities referring to natural talents and learned skills, Role Perception involving understanding one's tasks and behaviors, and Situational Factors comprising environmental conditions outside an individual's control. The document then examines methods for managing employee motivation, including through needs and drives, goal setting, expectancy theory, and extrinsic/intrinsic rewards.
