Motivation is what drives people to action and helps them achieve their goals. There are several theories of motivation. Maslow's hierarchy of needs proposes that people are motivated to fulfill basic physiological needs, then safety, social, esteem, and self-actualization needs. Herzberg's two-factor theory distinguishes between intrinsic job factors like achievement that bring satisfaction and extrinsic job factors like company policies that prevent dissatisfaction. McClelland identified three needs that drive motivation: achievement, affiliation, and power. Understanding different motivation theories can help managers stimulate employees to accomplish organizational objectives.
