Final answer:
It is false that key players and organizational structure are not important for a campaign plan client overview. Knowledge of company leadership is crucial for strategic planning and building relationships, despite broader investor familiarity with the firm's financial details.
Step-by-step explanation:
The statement that the key players and organizational structure of a company is not important to note for the client overview for a campaign plan is false. As a firm becomes established and its strategy is likely to lead to future profits, the need for external investors such as bondholders and shareholders to know the individual managers on a personal level diminishes. However, this does not negate the importance of understanding the company's leadership and structure, especially when planning a campaign, where such knowledge can guide strategic decisions and foster stronger relationships.
