Subject of Research. The paper considers a concept of platform approach for automated electronic devices design. The concepts of “platform-based development” and “unification and standardization of developments” are compared. Analysis was carried out on our own examples of ellipsometric equipment family development and the development of a nanosatellite platform of the CubeSat standard. Method. The decomposition of these platform solutions into unified modules is resented. Quantitative indicators of project-to-project unification were calculated for these two cases in accordance with regulatory documents. By experience, the typical value of the project-to-project unification indicator specified in the technical tasks for the development of devices ranges from 60 % and higher. Main Results. For the family of ellipsometers the value of project-to-project unification coefficient equal to 96.3 % was calculated. For the nanosatellite platform a value of project-to-project unification coefficient equal to 84 % was obtained. Both values exceed significantly the value of typical given values. It is shown that chosen fragmentations of platforms into unified modules outlined in the paper are optimal from functional differentiation between modules point of view. Practical Relevance. Advantages of the platform approach are demonstrated on personal experience of development of highspeed ellipsometric equipment and a universal nanosatellite platform of the CubeSat standard. It is shown that the obtained high rates of unification are achieved due to the modular principle implementation for design of electronic subsystems. Years of successful experience in effective design of new automated devices within the existing platform is consistent with qualitative calculations. The quantitative value of standardization and unification indicators can serve as a main factor for the adoption of engineering and management decisions on changes in the products being developed.
