The increasing complexity and scale of modern service organizations necessitate the development of sustainable business models that balance profitability, resilience, and long-term value creation. As service organizations grapple with globalization, digital transformation, and heightened stakeholder expectations, predictive and strategic insights emerge as critical enablers for building adaptive, future-proof business structures. This study investigates the role of predictive analytics, scenario planning, and strategic foresight in shaping sustainable business models for large-scale service organizations. It emphasizes how organizations can embed sustainability principles into their operational, financial, and customer-facing practices while leveraging data-driven insights to anticipate market trends, manage risks, and allocate resources efficiently. The research highlights current shortcomings in traditional business models, which often prioritize short-term efficiency over long-term resilience and stakeholder value. By integrating predictive tools such as advanced analytics, artificial intelligence, and big data visualization organizations can transition from reactive strategies to proactive, evidence-based decision-making. Strategic insights derived from market intelligence, customer behavior analysis, and industry benchmarking further ensure alignment between organizational goals and environmental, social, and governance (ESG) imperatives. Case illustrations demonstrate how large-scale service organizations can use predictive insights to design sustainable pricing models, optimize resource utilization, and foster innovation. Strategic integration of sustainability into the business model enhances accountability, strengthens stakeholder trust, and creates competitive advantage in volatile markets. The findings propose a multidimensional framework that connects predictive analytics with strategic foresight to deliver measurable outcomes across financial stability, operational efficiency, customer satisfaction, and sustainability impact. Ultimately, the study contributes to management practice by offering a roadmap for service organizations seeking to institutionalize sustainability through predictive and strategic insights. It underscores that sustainable business models are not merely reactive adaptations but proactive frameworks that ensure resilience, growth, and long-term relevance in an increasingly dynamic global service economy.
