Abstract: Taking manufacturing modularization as a reference, this paper interpreters the service modularization from the five dimensions, i.e., modularity division, modularity integration, modularity interface, modularity coupling degree, and the customization level of modularity, based on industrial or corporate cases. The findings show that the service modularization has the following different features. 1. It breaks the limitations of division and integration according to standardized interfaces in the manufacturing modularization, which is more conducive to the formation and integration of modularized value network. 2. It has a symbiotic interface of openness and integration, and a dual interface beyond the universal and standardized manufacturing modularization, which is easy to establish a new production cooperation relationship. 3. The complexity of the connector and the flexibility of the calling method can reduce the degree of coupling between modules, which can promote flexible operation of the modular organization. 4. In the aspect of personality customization model and intelligent customization technology, the interactive service modularization model can further improve customers’ satisfaction and loyalty.
