In the fast-changing climate of today’s organizations, leaders are required to stay flexible, responsive, and focused on growth—qualities that are key to adaptive leadership. This paper offers a comparative examination of two essential leadership frameworks—Blake and Mouton's Managerial Grid and Hersey and Blanchard’s Situational Leadership Model—viewed through the principles of adaptive leadership. Utilizing recent empirical research and theoretical insights from the years 2019 to 2024, we assess how applicable each model is for promoting leadership agility, team development, and resilience amidst instability. While the Managerial Grid offers a stable yet valuable perspective on leadership behavior by examining task orientation versus people orientation, the Situational Leadership model provides a more fluid approach, adapting leadership styles based on follower readiness and situational needs. Insights drawn from the healthcare, education, and corporate sectors during and following the COVID-19 pandemic highlight the growing importance of adaptability in leadership roles. Our results indicate that the Situational Leadership model aligns more closely with adaptive leadership in practical settings, particularly in circumstances characterized by uncertainty and the necessity for individual growth. The study concludes with a recommendation for a blended leadership strategy that combines the strengths of both models while incorporating key principles of adaptive leadership to effectively address the challenges faced by modern organizations.
