Because Theory expectancy is a belief about the future rather than a concrete existence in the environment, people's beliefs can vary greatly (Redmond, 2010). This means that while one person perceives their efforts to lead to a great accomplishment, another person may believe their same effort will not lead to much accomplishment at all. This difference in perceptions is due to many factors. Two factors that can affect expectancy are ability and interest (Redmond, 2010).
"Lack of ability or interest will decrease a person’s expectancy. With proper training and a high interest level, people will have an increased level of expectancy. Employers, for example, need to keep this in mind as they create ideas to motivate their employees. By encouraging employees and building self-efficacy, managers can increase employee expectancy" (Redmond, 2010).
