You are now at the point where it is necessary to put the details of your plan on paper. Implications for Your Plan If you have done your homework, you should know what arguments 'the other side' will pose. You should also have thought out how you would respond to criticisms. It is crucial that you treat any critics with respect. Don't get personal.
Every point of view has some merit.
It is important to listen, calmly, and then to give your response in a clear level-headed manner. Practise the answers to difficult questions beforehand. However you are communicating, state your core message. Anticipate questions that will be asked and know what your answer will be. If you plan properly, there should be little that happens that takes you by surprise whether it is in a meeting, in telephone conversation or in a casual encounter.
