This study investigates the relationship between Top Management Teams’ (TMTs) educational diversity and enterprise performance within the Upper Echelons Theory (UET) framework. It integrates data from ten qualitative interviews with senior managers and a quantitative survey of 765 small and medium-sized Latvian enterprises (SMEs) representatives. The study explores how educational background—a form of deep-level diversity—affects strategic decision-making, innovation, and financial outcomes across organizational contexts.
Findings suggest educational diversity is a valuable strategic asset, particularly in medium to large enterprises and knowledge-intensive sectors. Respondents highlighted that diverse academic backgrounds support problem-solving, particularly in crisis situations. However, the perceived value of education varied by demographic and organizational factors, including age, gender, language group, company size, and industry sector. While 64% of survey participants rated educational background as “very important” or “extremely important” for financial decision-making, others emphasized the complementary role of practical experience and collective managerial tenure.
The analysis confirms that education is not always the dominant factor in executive performance. Meanwhile, when combined with other dynamic traits such as risk tolerance and shared values, it significantly influences organizational outcomes. Sector-specific findings underscore that in industries with high complexity and change, such as technology, services, and manufacturing, educational diversity in TMTs plays a more critical role. In smaller companies—particularly those with 10 to 49 employees or annual revenues below €300,000—hands-on experience is often viewed as more important than formal education, as shown by lower support for educational diversity in these groups. In contrast, 63.92% of all surveyed enterprise representatives rated educational diversity in Top Management Teams (TMTs) as “very” or “extremely important” for financial decision-making, with this figure rising significantly in firms with over 50 employees or annual revenues above €5 million. Using these findings for companies in practical terms, it means that developing their leadership teams and being willing to stay competitive, should consider not only formal education but also ensure a diverse blend of academic backgrounds among top managers. The study supports the development of a mathematical model that incorporates both the educational and behavioural characteristics of TMTs. It also contributes to the broader understanding of how diversity management impacts firm-level performance and innovation in a regional context.
