Smart work is a new paradigm of the way of working for knowledge workers. We propose a model which determines the levels of smart work. As the determinants, we identify freedom from both space and time. As an extension of the model by adding a new determinant of the mobilization of social intelligence, we show that a new smart work model, smart work 2.0, can be derived. For successful implementation of smart work 2.0, we also provide strategic suggestions, along with the implication of the study and future research direction.
