Everyone has heard this phrase before, “Let us make it the right time with the right topic for the right people.” This same phrase needs to be part of the pre-planning on your speech. Think of this phrase as a triangle with time, content and people as the three sides. In order for the triangle to be strong, all sides have to balance.
Now it maybe that your boss is just asking you to make this speech to your co-workers about a current problem. Or an association is having a conference and they are asking you to speak about your expertise. The question of time, audience or content may not even be an issue.
The more you can look at the sides of the triangle and determine the relationships to each other: the easier you can decide if every aspect is balanced. . Knowing this bit of information may help craft a better speech.
