Corporate governance has become an essential component of organisational management because it promotes transparency, accountability, ethical leadership, and responsible decision-making. Strong governance practices enhance stakeholder confidence, improve operational efficiency, strengthen financial discipline, and support sustainable business growth. The present study examines the corporate governance practices adopted by Capgemini and evaluates their contribution to organisational performance. The study focuses on major governance dimensions such as board effectiveness, transparency, accountability, ethical business conduct, internal control systems, risk management, regulatory compliance, corporate social responsibility, and stakeholder satisfaction. The research is based on both primary and secondary data collected from organisational respondents, annual reports, governance reports, journals, and other published sources. The findings indicate that Capgemini has established an effective governance framework that promotes ethical business practices, strengthens internal controls, enhances regulatory compliance, and improves organisational sustainability. The study concludes that effective corporate governance significantly contributes to stakeholder trust, operational excellence, and long-term organisational success. The findings provide valuable insights for management professionals, investors, academicians, researchers, and students interested in corporate governance and sustainable business management.
