Models of proactive change management of projects for the creation and development of distributed information systems

This article considers approaches to the formation of models of proactive management of projects for the creation and development of distributed information systems. Features of distributed IT projects as a complex adaptive system that develops under numerous interrelated constraints are considered. It is concluded that the projects themselves are distributed. The main trends in the development of such systems were analyzed, the main patterns and problems were identified. The focus is on the consideration of the basic components of such systems and formalized models are proposed to describe their interaction. Attention is paid to the formation and implementation of projects to create complex systems based on distributed information systems, where the main features are the action of a significant number of complex influences from the turbulent external environment. The issues of project reactions to the effects of these changes were investigated. To address the management of such complex projects, a proactive approach is proposed. The consequences of changes in the processes of creating such systems are studied. A mathematical model of minimizing the effects of changes on project elements in the management of complex projects is proposed and an approach to the configuration management of such projects is proposed, which in general allows to build a scheme of effective project management.
