Which of the following options is not classified as an administrative function?

The correct choice identifies Personnel Support for Contingency Operations (PERSCO) as not classified as an administrative function. PERSCO is primarily focused on the management of personnel during deployment situations, providing essential support and ensuring that the right personnel are available and accounted for in contingency operations. This function is operational in nature, emphasizing the tactical side of personnel management in a crisis or deployment context.

In contrast, office management, executive support, and human resources are all functions that align closely with administrative roles. Office management typically involves overseeing daily operations within an office setting, facilitating productivity and efficiency. Executive support generally entails providing assistance to high-level executives, managing their schedules, communications, and various administrative tasks. Human resources are responsible for a wide range of employee-related functions, including recruitment, training, and compliance with labor laws, all of which are fundamentally administrative in nature. Thus, PERSCO stands apart as it operates primarily in field conditions rather than the administrative environment.
