A polished script can help an executive present clearly until the audience asks a question in a different order. The presenter then has to choose between following the rehearsal and addressing the actual concern.
Preparation should develop command of the material as well as fluency in delivering it.
Practice the variations
Ask a colleague to interrupt, request the conclusion early and challenge an assumption. Explain the recommendation without the slides. If an answer becomes difficult, identify whether the gap is in knowledge, reasoning or wording.
Prepare short and detailed versions of the main explanation. A director who wants the commercial consequence should not have to wait through every analytical step before hearing it.

Avoid rehearsing only with people who already know and support the proposal. Familiarity can make an explanation appear clearer than it is.
Leave room to think
Know which points are essential and which can be omitted when time changes. Plan how to acknowledge missing information and commit to a follow-up.
During the event, listen to the question before retrieving the answer you practiced. If necessary, restate the issue to check that you understood it.
Afterward, review where the conversation departed from the rehearsal. Some departures reveal better ways to explain the material; others reveal an issue the proposal itself needs to address. Preparation is working when it helps the executive respond to either.
