Final answer:
Flora is engaged in the controlling function of management, which entails monitoring and adjusting an organization's performance to meet set goals.
Step-by-step explanation:
When Flora is comparing the monthly budget to actual revenues and expenses, she is engaged in the controlling function of management. This process involves monitoring the organization's performance and making necessary adjustments to meet established goals. Controlling is key in ensuring that the company follows the strategic plan that has been set. This function is distinct from directing (guiding employees towards organizational objectives), planning (setting out the future course of action), organizing (arranging resources to carry out plans), and coordinating (aligning team efforts).
