Final answer:
Leaders can impact an organization's culture by focusing on, measuring, and controlling organizational communication, which is central to influencing the company's values, beliefs, and attitudes.
Step-by-step explanation:
Leaders looking to change an organization's culture can pay attention to, measure, and control several aspects, but not all variables are within their direct influence. The best option that leaders can manage to effect change in the culture of a company or organization would be organizational communication. Employees' personal lives are generally off-limits, legal requirements must guide financial performance, and organizations can only adapt to external market trends rather than control them. Therefore, focusing on how communication is conducted within the company can have a significant impact on the culture by influencing values, beliefs, attitudes, and systems.
