Final answer:
Understanding the audience's needs is a critical initial step in the planning process of a business presentation, not the last, as it shapes the entire narrative and approach of the presentation.
Step-by-step explanation:
The statement that gaining a deeper understanding of the needs of the audience should be the last step in the planning process of developing a business presentation is false. When planning a business presentation, understanding the audience's needs, expectations, and background knowledge is one of the first steps, not the last. This vital step informs the content, tone, approach, and style of the presentation.
It guides the creation of the presentation script or outline, influencing aspects ranging from the complexity of the information presented to the types of evidence or persuasion needed. Understanding the audience helps in shaping the narrative to make it relevant and meaningful for the intended recipients of the message.
