Do – understand your audience – make sure you are giving information at the appropriate level.
Don’t – assume your audience knows as much about the subject as you – remember they are there to learn something new.
Do – structure your presentation clearly – see ‘Sorting out your Message’.
Don’t – include any new information or ideas in your conclusion.
Do – check in advance that all the facilities you need are available – have a plan B just in case.
Don’t – waste your audience’s time by fiddling with equipment – all such preparation should be done before they arrive.
Do – put energy into your presentation – if you are not enthusiastic how can you expect your audience to be?
Don’t – rush your presentation – give your audience time to assimilate the information.
Do – use the correct tone for your message – any mismatch and people will focus on your body language and not on what you say.
Don’t – give an urgent message in a laid back manner, or a reassuring message in an aggressive tone.
AND PRACTISE! PRACTISE! PRACTISE!
