The purpose of a persuasive speech is to make the audience see a certain issue your way. In order to accomplish this goal, you need to use compelling arguments, because people with strong opinions can be really difficult to sway. Following Monroe’s motivated sequence can be very helpful.

It is a good idea to start with attention-grabbing opening statement regarding the topic. It could be a rhetorical question or a thought-provoking story, or even some shocking information.
Afterwards you can mention why your speech may be of interest to the listeners.

The next important part is the need step, where you should lay down the problem that has to be solved. You could either contend that the present state of affairs has to be changed, or, alternatively, that it has to be preserved exactly the way it is. To back up your statement you can employ some additional information, such as examples illustrating the need and making it more convincing.

After formulating the problem you should present a possible solution, this way moving to the satisfaction step. Briefly explain the way you think things could be improved and support your proposal with logical argumentation and examples of how it was successfully realized before. In this fashion you provide both theoretical and practical validation of your ideas.

The next step is visualization, in which you illustrate what is going to happen if your solution is implemented or if it isn’t. The goal is to make your description very vivid and realistic.

Now move ahead to the final part: the conclusion (or the action step). Here you can summarize your main ideas and offer a specific course of action the listeners can take to become part of the solution.
