The secret is the top down sequence.

First state the question and in a few words explain the context.
Second, state your conclusion.
Third, state how many reasons you have for your conclusion.
Fourth, say what each reason is about and then give details.
Fifth, repeat your conclusion.
For example:
“The question is whether the house on 6th Street should be demolished.
My view is that it should be.
I have two reasons for this.
First, it is a health hazard: The walls are broken. The roof is beyond repair. The building is infested with rats.
Second, It is a fire hazard: The rooms are full of rubbish, broken wood and other flammable material. Vagrants light fires in the ruin.
Consequently, my view is that the house should be demolished.”
Note:
- The hearer is immediately knows what the communication is about.
- The hearer is immediately told the conclusion.
- The hearer is told there will be two supporting reasons.
- The hearer is given a warning that a reason is coming, is told what the reason is and then is given details.
- The hearer is again told the conclusion.
