The paper presents a new view of quality evaluation of a system of electronic data exchange between a business and government. A method for evaluation of the electronic data exchange system between a business and state authorities is presented in the paper. The method is called CBG (Communication between Business and Government). A goal of the CBG method is to evaluate the system of electronic data exchange between a business and state authorities, not only to evaluate applications such as an electronic data box or an electronic submission of tax. A pilot version of the CBG method provides a tool to evaluate and measure important attributes of the electronic data exchange system between businesses and state authorities
