The theory does not offer clear cut guidelines. The ERG theory implies that individuals will be motivated to engage in behavior which will satisfy one of the three sets of needs postulated by the theory. In order to predict what behavior any given person will be motivated to engage in would require an assessment of that person to determine which of the three needs were most salient and most important to that person. The individuals would then be predicted to engage in behavior which would lead to the attainment of outcomes, with the capacity of fulfilling these salient needs.
