Psychologist David McClelland studied workplace motivation extensively and theorized that workers as well as their superiors have needs that influence their performance at work. One of these needs is Achievement Motivation - which can be defined as an individual`s need to meet realistic goals, receive feedback and experience a sense of accomplishment. To create a work environment that helps employees experience a sense of accomplishment, we need to understand employee aspirations and provide the means to accomplishment, through aspiration management. According to McClelland,understanding human motivation ought to be a good thing as it opens up opportunities of self-development if we apply motivational principles to pursuing our goals in life.
