The present paper tracks the attitudes of the Bulgarian students towards online education provided by the universities during the quarantine period due to the pandemic situation caused by COVID-19. The study presents data and analysis of results from an empirical survey conducted in April 2020 among students in different stages of their tertiary education in Bachelor Degree. Our findings show that students define online lectures with the same quality as traditional lectures in auditoriums. In terms of intensity there is no clear expressed opinion of responders with slight predominance of people who claim that the intensity of online learning is less than the traditional lecture. Major part of responded students claims that they manage to focus better in online lecture. Students are convinced that in online environment they work easier in individual tasks, but not in team works.

Competitiveness is a key feature for the management of the modern organizations. Its development and sustainability are based on the use of the available resources with optimal efficiency, the organization's ability to adapt to the fast changing environment, as well as the speed and efficiency of the implementation of innovations. The purposeful increase of an organization's competitiveness is connected with investments in human resources development, technological renovations and improvement of the work conditions as a whole.

The present paper represents methodological approach for effectiveness and efficiency of IT project management, part of a comprehensive research in Bulgarian high-tech companies. Traditional and Agile methods are explored on the base of different developed indicators establishing wasted time and increased costs for the final product and result, due to the imperfection in IT project management of the companies.

Introduction. Digital transformation has become a determinant factor influencing enterprises’ economic security, especially during crises and global concurrences. Despite its numerous advantages, digitalisation poses new risks, such as cyber threats, regulatory instability, and information leaks. Digitalisation as an infrastructure for innovation has become a strategic priority, primarily through the extension of digital government services, cloud resolutions, and metadata analytical tools to support the economic development of industry enterprises. Aim and tasks. This study aims to develop an integrated system of strategic risk management for digital transformation in industry enterprises’ economic security to minimise economic losses, increase adaptiveness to digital changes, and eliminate risks in industry enterprises’ economic security. Results. This study analyses modern approaches to ensuring economic security: systemic, risk-oriented, resource-oriented, and integrated approaches. The analysis revealed that only 25.6% of IT enterprises utilise Big Data analytics, while 7.1% employ AI technologies, highlighting the substantial untapped potential for further digital transformation. This study developed a structural model of a digital economic security management platform, including risk analytics, threat management, cyber protection, monitoring, and reporting. A formalised risk estimation model was built, considering financial, operational, and external factors. An integrated approach is suggested to build a digital platform for the management of enterprises’ economic security, which combines risk-oriented methods, cyber-protection, and big data analytics. Conclusions. This study proposes an approach for digital transformation in economic security management, featuring module architecture to monitor, forecast, and respond to threats. It presents formalised module architecture and a platform structural model for economic security monitoring, comprising four subsystems: financial, operational, risk-oriented, and external factors. The model enables rational resource allocation, threat forecasting, and adaptive decision-making in post-conflict scenarios. Enterprise digital transformation in strategic management and economic security is a key requirement for restoring, strengthening, and safeguarding the national interest.

Bulgarian Industrial Small and Medium Sized Enterprises (SMEs) have to be really innovative and flexible in order not only to survive at the market, but to develop competitive advantages. Decisions today are not necessary to be the right for tomorrow, but still the management should try to react proactively to this uncertain environment. Change management is difficult and complex process that becomes even more complicated when we consider change for industrial enterprises in terms of financial and human dimensions. In order to decrease uncertainty in the process of planning and implementation change, we elaborate the methods for risk analysis and on this base - to help managers to eliminate in some degree the uncertainty.
