Just as with introductions, there are two important points to remember from the start. First, regardless of the form of conclusion, all summary remarks must meet certain required functions. Second, most conclusions will be a combination of two or more forms. There is a third point to remember about conclusions as well: Conclusions need to provide a match to the introduction, so that there is symmetry and completeness to the speech structure. Because of this, very often, the conclusion will be of the same form as the introduction. At the very least, the conclusion must refer to the introduction so there is a sense of completeness. Naturally enough, the forms of conclusions you can use and develop are similar to the forms of introductions you can use and develop.
Eloquent speech is not from lip to ear, but rather from heart to heart. ~ William Jennings Bryan
Prepare the Conclusion
The conclusion is the last part of the speech to prepare.
What is common writing practice for the introduction is also true of the conclusion. As previously discussed, introductions and conclusions are similar in nature, they provide mirror images of one another other, and they are often of the same type. So you complete the introduction and conclusion at the same time. You do so to make sure that both elements work together.
As you prepare the conclusion, make sure as well that there are no false conclusions. You need to prepare the audience for the end of the speech—but you can only prepare them one time, and there can be only one end to the speech. By the same token, you need to make sure that the conclusion is not so abrupt or sudden that no one in the audience is aware you have completed your speech. Keep in mind as well that conclusions should comprise no more than 10% of the total speaking time.
Just as with the introduction, write out the conclusion word for word. This is your last chance to impress your audience and to make sure that they understand what you have said. Do not leave the conclusion to chance: write it out.
Success depends upon previous preparation, and without such preparation there is sure to be failure. ~ Confucius
Do Not Include Any New Information
While it is important to present your appeal and any call to action in the conclusion, it is also important to NOT present new information in your conclusion. Remember: one of the functions of the conclusion is to prepare the audience for the end of the speech. If all of the sudden you present a new argument, new information, or a new point, you will confuse your audience.
If you present new information in the conclusion, you will also lose the ability to integrate this information with the rest of the speech. Remember that all elements of the speech need to flow together. New ideas at the very end of the speech will not enhance the flow of the speech. Additionally, because you are just now bringing in this information at the end of the speech, you will have no or very little time to develop these ideas, or to provide supporting information and documentation for these ideas.
Follow the Structure
The approach of using the built-in structure of the specific introduction/conclusion technique is as equally effective with quotations, questions and startling statistics as it is with stories.
You can use the same quotation at the end as at the beginning, but because of what we have learned in the speech, the quotation has a new and more developed meaning. You can also use a new quotation that draws a comparison and contrast to the beginning quotation, and also highlights what we have learned in the speech.
You can use the same question at the conclusion as you did at the beginning, and regardless of whether you ask for a response or pose it as a rhetorical question (and allow the audience to consider the answer), the answer will be different because of your speech. The audience will be able to see what you have accomplished in the speech. You can also pose a new question, one that again points out what the audience has learned from your speech.
Startling statistics, as quotations and questions, now take on new meaning because of all that you have told the audience in your speech. Reminding the audience of startling statistics should provide them with a key reminder of the main point of your speech.
