The three keys components to a great presentation are:
For example, your presenting on technology for the AEC industry (Architecture, Engineering and Construction). The Content may be examples of technology you can use such as smart boards, tablets, software etc. The Context would be how they integrate with what you do and how you do it and the Credibility comes from an example of how using this certain app or software saved you money or time in the field.
The Credibility is important, if you cant back up what you have just said your whole presentation falls apart, you cant back up what you have just told someone.
Remember these three rules and make your presentation memorable.
Oh! And the topic my colleague it presenting is "Business Development for Introvert"
