It is difficult to give an effective presentation, take notes, answer the questions and read the reactions of your audience all at the same time. So when making presentations, I have found it helpful to team up with a colleague. While one person is talking or presenting the other is taking notes and watching the people in the room. During the presentation we can easily swap these roles so each person get enough air time in the presentation. After the meeting we compare notes and observations to get the full picture. My partner then has the opportunity afterwards to give me a pointer or enlighten me on something I missed in the conversation so I can improve my skills going forward. So by presenting with a partner, you can give more attention to your audience and have more attentive follow-up while improving your skillset. A win-win-win.
