We use the decision chain as a tool to help us make decisions on our own. You can use these same steps in your speech to guide your audience to make the decision you want them to make.
Decision Chain: Problem? No Problem With Decision Chain!
Problem: What's the problem you are addressing? (This is where your story fits in - putting the audience in the shoes of someone facing your problem so that they really understand the problem.)
Need to Know: Present facts about your problem.
Pros/Cons: What are the positive things about making the choice you want your audience to make? What are the negative things about not making this choice?
Weigh: After weighing the options, tell the audience what
you think is the right thing to do.
Decide: Present options for your audience to choose and decide between.
Commit: Ask your audience to commit to one specific action.
