Enterprise informatization is not perfect. A key factor of jit procurement success is a high degree of information sharing between supply and demand sides. On the whole, however, due to the lack of relevant technical talents and limited financial strength of enterprises, the informatization level of manufacturing enterprises in China is still relatively backward, and comprehensive informatization management has not been realized.
