An operational definition is used for a behavior so that the behavior can be properly described and understood. Without an operational definition, it would be difficult to describe behavior without being subjective. Therefore, behavior cannot be understood and cannot be correctly addressed. It is also important to understand how behavior functions so that the antecedents and consequences of behavior can be observed. Thus, what reinforces or affects the behavior can be better understood. Lastly, an operational definition is objective and specific, therefore, behavior can be described across different settings and times.
