This chapter introduces the central themes of Concepts of Corporate and Public Governance: Building Identity, Brand, Image and Reputation in the Digital Era. It highlights how digital transformation and globalisation have reshaped governance in both corporate/private and public sectors, expanding its role beyond regulatory compliance to encompass strategic leadership, transparency, and stakeholder engagement. The chapter begins by defining governance concepts, then briefly defines corporate governance as the framework for directing and controlling companies, and public governance as the system by which governments manage public administration and resources. It explains the interconnectedness between governance practices, identity, branding , image and reputation, stressing that effective governance enhances organisational credibility, stakeholder trust, and long-term sustainability, while non-compliance leads to reputational and financial risks. The chapter outlines the book’s objectives, which are to address gaps in understanding the relationship between governance, identity, brand, image and reputation, integrating theoretical and practical perspectives, and provide case studies illustrating real-world applications. It emphasises the importance of ethical conduct, accountability, and digital-era challenges, offering insights for leaders, policymakers, academics, and students seeking to strengthen governance and brand reputation in a rapidly evolving environment.
