Abstract

The article provides a comparative analysis of models of digital platforms of public services used in egovernment: centralized, federated, modular and registry-oriented. It is shown that the choice of architectural model determines not only the technical characteristics of the platform, but also the possibilities of reengineering (deep redesign) of e-services business processes, the degree of component reuse, flexibility of changes and operational stability. A formal multi-criteria model for evaluating a digital platform is proposed, which includes the registry compatibility index, the application programming interface (API) maturity index, the integration complexity index and the integral reengineering feasibility index. An approach to modeling the transition between architectural models during service reengineering is developed, taking into account resource constraints, regulatory requirements and organizational readiness. An example of using the Matlab environment to visualize the integration complexity profiles of different platform models is given, as well as pseudocode for the transition planning algorithm between them. The main barriers to the implementation of modernized platforms are outlined: fragmentation of registries, lack of unified directories, low API standardization, inertia of back-office processes, personnel and institutional constraints. Ways to overcome these barriers are proposed: creation of a national interoperability framework, sequential reengineering of critical processes, phased migration to a registry-oriented or modular platform, application of contracts at the service and data levels, as well as the use of event log analytics to prioritize changes. The results can be used by public authorities when choosing a target e-government architecture, planning digital transformation programs, and justifying investments in reengineering e-services.
