Motivation is defined as stimulating someone to achieve desired goals or take desired actions. It is a process that involves motives, behaviors, goals, and feedback. There are intrinsic and extrinsic types of motivation. Classical theories focused on fear/punishment and rewards while modern theories examine needs, expectations, and fairness. Motivation results from an interaction between individual factors like needs, expectations, and personal agency beliefs, and situational/organizational factors like rewards, fairness, and job design.
