Abstract
The practical implementation of high-tech projects is becoming essential and relevant throughout the world in the era of the digitalisation of various industries. The successful completion of high-tech projects will indeed support the development of domestic markets and the economy's competitiveness. It should be noted that high-tech projects involve breakthrough technologies and innovations, which, in turn, need effective management. This research aims to assess the relationship between the project management application processes and the effectiveness of projects in the industrial sector of countries such as Japan, Israel and Kazakhstan. The main focus of this paper is analysing high-tech project management in the engineering, green production, chemical and atomic sectors of these three countries. As a result, Japan is ahead of Israel and Kazakhstan. This research also contains an assessment of the maturity levels of project management of the chosen countries. The study used a systematic literature review, comparative analysis, quantitative data collection methods through interviews, statistical analysis and modelling. As a result, data were obtained on the project performance level in the selected countries, and approaches to managing high-tech projects in the industrial sector were proposed. A process methodology that may be implemented as a map for each set of projects has been created by assessing necessary success steps for high-tech projects. The study also recommends the number of instruments and techniques for Kazakhstan's high-tech project management. According to the findings of the statistical study, their application in the management of high-tech development will help the project be successfully completed.
