Theoretical and methodological provisions of the concepts of change management and reengineering, prospects for their integration: difference and convergence

Current economic situation both at macro- and micro-level is characterized by permanent changes. The response of the business entity is quite predictable, justified and logical, and it is not doubted in the modern theory and practice of management. The relevant issue is the format of such a response, which is based on organizational transformations of different nature but, in spite of this, in one way or another, capable of combining and forming sustainable scientific approaches and practices of organizing effective management systems. Modern paradigm of management implements two strategies (concepts) of organizational transformations: reengineering and change management. The above mentioned strategies have specific features in theoretical interpretation as well as in their practical realization, possess certain convergence of the propositions in scientific and empirical aspects of public production management.Theoretical and methodological grounds for solving the problems of the study are based on applying the principles of system, risk-oriented, programmatic-targeted and situational-sce­nario approaches. The informational basis of the scientific research involves the works of do­mestic and foreign scientists on the selected issue.As a result of the study, the authors have verified the convergence and differences of the main propositions of the concepts “change management†and “reengineering†, determined their subject areas, theoretical basis and methodological principles, identified the directions for de­velopment and integration of the concepts under study.The definition of the cost of an investment project at the stages of formation of the concept and pre-investment research using specific indicators is considered as a specific tool for such integration.It has been stated that integration of reengineering and change management at the corporate level will make it possible to ensure both sustainability in development and flexibility in in­teraction with the surrounding economic environment, increase the life cycle of the business entity and its products, and in the end, not only create competitive advantages, but also gain a synergistic effect from such integration.
