THE DIALECTICAL RELATIONSHIP OF FLEXIBILITY AND SUSTAINABILITY OF THE PROJECT MANAGEMENT SYSTEM
Introduction. The problem investigated in this paper is that from the standpoint of dialectics flexibility and stability are opposite properties of systems. As a result, the stability of the project management system and the flexibility of this system are in conflict. But in practice, there is a pressing issue of the possibility of sharing the concepts of flexibility and sustainability of project management. The answer to this question is offered by the authors. The purpose of the study is to substantiate the idea of integrated use of the concepts of sustainability and flexibility of project management. The methods of research are abstract analysis, dialectical analysis of the essence, unity and opposites in the development of the concepts of stability and flexibility. The results were the following provisions. On the one hand, stability and flexibility dialectically contain opposite properties of systems - to be stable or flexibly modified. On the other hand, the authors propose their own methodology for the integrated use of flexibility and sustainability of the project management system. The main idea of this methodology is to distinguish the elements of the system, some of which should be stable and some flexible. This allows the system to be flexible in terms of the methods and technologies used in the operational mode and to be sustainable in the long term, while maintaining relatively stable strategic goals, values, principles of operation. The main conclusion was the statement about the possibility and advantages of sharing the flexibility and sustainability of the project management system.
