Chief administrative officers direct a company day-to-day administrative operations, including human resources, budget tracking, and regulatory compliance. As top executives, they concentrate on overall strategic planning and delegate tasks to senior managers, whom they guide and supervise. In turn, they report directly to the CEO about the company status. Because much of business performance depends on them, chief administrative officers should be able to thrive in a challenging, fast-paced environment that may require more than 40 hours every week.
