Organizations today operate in a rapidly changing environment shaped by technological advances, shifting workforce expectations, and heightened sustainability demands. This paper examines contemporary practices in management and administration that enable organizations to remain agile, efficient, and socially responsible. Focusing on three interrelated domains — digital transformation, people-centred management, and sustainability-oriented administration — the study synthesizes recent literature and illustrative case examples to identify common approaches and outcomes. Digital transformation initiatives (including automation, cloud management systems, and data analytics) are shown to streamline processes and improve decision quality, but require parallel investments in digital skills and governance. People-centred practices such as flexible/hybrid work models, agile leadership, and continuous learning foster engagement and innovation, yet success depends on clear communication and inclusive cultures. Sustainability-oriented administrative reforms integrate environmental and ethical considerations into procurement, reporting, and strategic planning, strengthening stakeholder trust and long-term viability. The study also discusses barriers to adoption — skill shortages, legacy systems, privacy concerns, and change resistance — and proposes a practical framework for phased implementation combining leadership commitment, cross-functional teams, and performance metrics. Findings suggest that organizations that intentionally combine technology, human capital development, and sustainability goals achieve better adaptability and stakeholder outcomes. The paper concludes with recommendations for managers and administrators to prioritize digital literacy, foster adaptive cultures, and embed sustainability in routine administrative processes to prepare for future disruptions.
