The current, fast market changes require enterprises to dynamically adapt the way they conduct their business. This poses many challenges for information technology. Market requirements for immediate response to business changes became the basis of the idea of a real-time information processing (RTE) company. RTE provides real-time information to employees and business partners. Integrated IT systems supporting management constitute a common platform – the foundation of a real-time enterprise. The aim of the article is to present the basic problems of building an IT system that is the basis of a real-time information processing (RTE) company. It is a summary of our work on this type of system. The article justifies the thesis about the need to build a system for the RTE’s requirements and the conditions of its implementation. Such a system is designed to provide employees and business partners with the information they need in real time. The use of integrated systems such as ERP, CRM, SCM, and so on provides the ability to implement the main business processes of a real-time enterprise. The article presents both literature analysis and the characteristics of own work on designing IT systems for RTE. Particular attention was paid to the analysis of success factors (determinants) in system design and the use of MUST methodology (MUST is a Danish acronym for theories of and methods for design activities). The final part of the article presents a proposal for further work on IT systems for RTE in the context of existing trends such as DARQ technology (Distributed Ledger, Artificial Intelligence, Extended Reality, Quantum computing).

Constant changes in the market and increased competition make it necessary to dynamically adapt the way of running a business. The pressure of constant changes implies the emergence of requirements for information technology, which is the basic tool for information processing in organizations. The necessity of immediate reaction to business changes, reduction of time of business processes realization, immediate retrieval of information and its sharing, became the foundation of the idea of a company processing real-time information (Real Time Enterprise, RTE). RTE provides real-time information to employees, customers, suppliers, and other business partners, ensuring timeliness and consistency across all IT systems. The possibilities of RTE implementation thus become an important element of the IT operation and the entire enterprise. It seems to be advisable to find determinants of designing a proper IT system supporting the operation of an enterprise that processes information in real time (RTE).
