Research subject. Information interaction of the user with the information system.
Objective. Improving the efficiency of user interaction with the information system to solve the main problem by customizing its interface and work script. Core results. The proposed methodology of scientific research aimed at achieving the goal, and consisting of 3 steps. As a result of each of them, the following main scientific results are expected to be obtained: interaction model, interaction assessment method, interaction optimization method. Also, it is expected to obtain private scientific results: the classification of the disadvantages of interaction, the influence of its parameters on the final efficiency, the architecture of the interface and scenario optimization system. Main conclusions. The proposed research scheme is scientifically correct and allows you to conduct a fullfledged scientific research and achieve the goal of the work. As a result, a method and a software tool will be developed that will make it possible to adjust a specific interface and a scenario for its work according to its own performance criteria - potency, operativeness and resource efficiency; at the same time, the general logic of solving the problem by the information system will remain unchanged.
