The statement implies that the boundaries of Public Administration (PA) are defined by the evolving activities and functions performed by the administrative system. This suggests a dynamic rather than a fixed scope. Historically, PA's scope was narrowly confined to policy implementation, emphasizing efficiency and economy, particularly during the era of the politics-administration dichotomy. However, this limited view proved unsustainable as governmental functions expanded significantly.

In contemporary times, the administrative system's involvement spans a vast array of activities, including policy formulation, implementation, evaluation, public service delivery, financial management, human resource management, organizational behavior, ethics, and international relations. Consequently, the scope of PA has broadened to encompass these diverse areas.

While stating that the scope is 'boundaryless' might be an overstatement, it effectively captures PA's interdisciplinary and pervasive nature. Public Administration draws insights from various disciplines such as political science, economics, sociology, psychology, law, management, and ethics. It concerns itself with both the 'what' (policy content) and the 'how' (implementation processes) of governance. Global challenges, technological advancements, and complex societal problems further blur traditional disciplinary lines, requiring public administrators to engage with diverse stakeholders and address multifaceted issues.

Therefore, PA is not literally 'boundaryless' in the sense of lacking a distinct identity. Instead, its scope is expansive, fluid, and constantly adapting to the evolving roles and responsibilities of the state. It is more accurately described as boundary-spanning, reflecting the comprehensive and interconnected nature of governmental functions in a complex and ever-changing world.
