The rapid development of digital technology, artificial intelligence, and global market dynamics has created an increasingly hypercompetitive and unpredictable business landscape. This research examines the role of adaptive mindset and digital technology in improving organizational performance in this challenging environment. Using a mixed-methods sequential exploratory approach with three phases-systematic literature analysis, multi-site case studies across 8 organizations, and quantitative surveys involving 785 employees from 12 technology companies-this study identifies effective strategies for managing employee mindset in the digital era. Findings reveal that organizations with a growth mindset culture experience 23% higher work engagement, 18% increase in product innovation, and 15% improvement in employee retention compared to organizations with fixed mindset. Digital mindset serves as a critical mediator between technology adoption and digital transformation success, with a correlation coefficient of 0.78 between digital literacy and operational productivity. Transformational leadership adopting paradox mindset improves team adaptability to technological disruption by 31% while reducing change resistance among baby boomer generation by 40%. This research extends Carol Dweck's theory by introducing the digital agility mindset concept, integrating continuous learning principles with cutting-edge technological competencies, and provides practical frameworks for assessing digital readiness and implementing leadership digital coaching.
