In an era of rapid technological advancement and global market fluctuations, traditional management approaches are proving insufficient. This paper investigates innovative management practices (IMPs) that contribute to sustainable organizational development. Using a mixed-methods approach—quantitative surveys of mid-level managers and qualitative interviews with executives across three industries — we examine how practices such as agile leadership, design thinking, data-driven decision-making, and decentralized structures enhance adaptability, employee engagement, and long-term performance. The findings suggest that organizations that actively implement IMPs experience up to 27% higher operational efficiency and a 35% increase in innovation output. The study contributes to the body of knowledge by offering a framework for embedding innovation into core management processes.
