Abstract

This academic article aims to: 1) examine the influence of self-efficacy on business presentation competence; 2) synthesize the distinct characteristics and unique strengths of extrovert, introvert, and ambivert personalities affecting presentation styles; and 3) propose strategic personality diversity management guidelines to optimize presenter performance. The study emphasizes that presentation skills are a critical strategic tool in the business world; however, presenters frequently encounter obstacles such as public speaking anxiety and one-size-fits-all training models that fail to address individual differences. Consequently, this research integrates the Big Five Personality Traits theory and the concept of self-efficacy to establish a new conceptual framework for authentically unlocking the unique potential of presenters.


The findings reveal that: 1) self-efficacy serves as a vital mechanism for managing anxiety, with optimum efficacy levels reducing the risk of one-way communication and enhancing credibility; 2) presenter strengths vary significantly by personality type, with extroverts excelling through the social presence, introverts possessing strengths in in-depth preparation, and ambiverts demonstrating the highest levels of behavioral flexibility and balance; and 3) Strategic management should focus on designing flexible communication channels, including both synchronous and asynchronous formats, while promoting psychological safety. Furthermore, organizations must shift their culture from overvaluing mere assertiveness toward appreciating data accuracy and adaptability, which are essential for supporting a sustainable competitive advantage.
