An interdisciplinary perspective of employee motivation is presented, based on the premise that the principles of natural science provide the fundamental basis for analogizing the operational similarities of physical and social productive systems. This concept is applied to motivation by observing that all productive systems--whether physical, organic or social--are input-output systems. The lowest common denominators in these systems are energy and mass. Le Chatelier's principle provides the universal environment for motivation. Thus, the transformation of energy in a given productive system represents the essence of motivation. The usefulness of analogizing the process of energy transformation in these two seemingly diverse systems can be seen by tracing the essential factors leading to efficient energy expenditure is physical systems and applying similar strategies to energy transformation in social system. Such an approach will provide the manager with a concrete frame of reference from which to draw plausible remedies in solving the innumerable problems of efficient motivation and utilization of employee energies.
