We analyze some foreign and Russian e-government development practices and propose the creation of the structured policy based on the PMI project management standards. We offer the IDEF0 standard as a methodology for public authority project management. Also, we suggest the workflow class notation for the lower levels. However, the current notation tools are not enough to reflect all the business processes of the e-services for public authorities. We propose a methodology for the project management development with some extra elements (objects and subjects) designed to describe the process types and the corresponding e-services more precisely. The additional task which was successfully solved thanks to the proposed e-services design technology is that the data security requirements were accomplished. We also describe how to use the offered approach to design the information systems and secure e-services for providing the citizens and the legal entities the land which is in the state possession.
