Two structure models of capacity and coordination in the IT system are composed firstly, and the data envelopment analysis (DEA) is selected as an evaluating method. The solving path of DEA model with non- Archimedes infinitesimal parameter is discussed. Then, the DEA method is used to define the capacity of infrastructure, or economic development and potential demand, as well as the validity of coordination, validity of development, and comprehensive validity in IT system. Considering the similarities and differences
