The article substantiates the theoretical and methodological foundations of assessing the professional development of managerial personnel in the context of post-war economic recovery. Professional development is conceptualized as a continuous, systemic process of enhancing managerial knowledge, competencies, and skills, which directly affect organizational efficiency and competitiveness. The study emphasizes the need to design a comprehensive system of indicators and an integral index that enables the quantitative assessment of managerial growth. The proposed methodological framework relies on factor analysis and the taxonomy method, applied to industrial enterprises of the Kharkiv region. The results reveal that some companies demonstrate high investment efficiency in personnel development, while others face challenges in automation and career advancement. The integral index enables the correlation of managerial performance outcomes, such as increased revenue and reduced losses, with investments in training, social benefits, digitalization, and career planning. It provides a tool for monitoring efficiency and optimizing investment priorities. The findings highlight the multilevel character of managerial development (individual, organizational, national) and the significance of combining formal and informal learning mechanisms. A comprehensive approach to evaluating managerial staff ensures alignment of competencies with strategic organizational needs and supports evidence-based decisions on promotion, training, and motivation. The study concludes that institutionalization of systematic professional development, reinforced by collective agreements, personnel development funds, and digital knowledge management, is critical in post-war conditions. The outcomes possess theoretical and practical relevance, offering recommendations for differentiated strategies to enhance managerial effectiveness and adaptability of enterprises to the challenges of the modern economy. Ultimately, professional development of managerial personnel is not only an economic and social category but also a determinant of national recovery and long-term competitiveness. Keywords: managerial personnel, enterprise, training, efficiency, integral indicator.
