The paper presents a study of the problems of organizing the process of designing technical means that are involved in the technological process of production by enterprises. Under the technical means it is proposed to understand both software, hardware, and software and hardware solutions. The main problem is identified - the discrepancy between the functionality of technical means and the technological process. In this regard, a study is being made of the processes of linking the technological process of output of enterprises with the processes of designing and developing technical means. From the results of the study, it was determined that the models of the functional of technical means are constructed by developers, and not by actors. Such models are formally presented not as a description of the procedures for performing the functions of a technological process by actors, but as a model of how the functions of future technical means will be used by actors. The necessity is substantiated and a hypothesis is put forward about the possibility of solving the indicated problem.

The article deals with the problems of communication between the customer and the development team in the process of designing information systems. Based on the identified shortcomings of existing solutions, a conclusion is made about the need to develop a new approach and means of its implementation. The paper sets the task of developing a common model for the interaction of subjects using a single platform. The article describes the concept and modular architecture of the platform for implementing the system notation for designing architectural schemes. The modules of such a platform and its general functionality are considered.
