Here's why:
* Over-reliance on the outline: Focusing too heavily on the outline can make the speaker sound like they are reading from a script, lacking spontaneity and natural flow.
* Loss of connection with the audience: If the speaker is too preoccupied with sticking to the outline, they may miss opportunities to engage with the audience, respond to their reactions, or adjust their message based on the room's energy.
* Limited flexibility: While an outline provides structure, it can also limit the speaker's ability to deviate from the plan if necessary. Sometimes a spontaneous thought or an audience response requires a change in direction, and a rigid outline can hinder this.
However, it's important to note that outlining is a valuable tool, and a well-prepared speaker can use it effectively without sacrificing their natural delivery. The key is to use the outline as a guide rather than a strict script.
