Focus on the Sale
You may think that you are not giving a sales presentation and therefore, you don't need to be convincing, but it is difficult to imagine any sort of public-speaking engagement where you aren't even slightly trying to persuade, cajole, convince or sell something. Even if you are just presenting your department's numbers for the month, you still want to "sell" the idea that your department is either performing well and deserves recognition, or that it is in need of extra resources and attention. Just paying the slightest attention to salesmanship can really help motivate you to put more of your personality into the presentation.
Don't go overboard--by salesmanship we're not talking about "Crazy Dave's Discount Mattress Madness" commercials or anything like that, we just mean 1) getting enthusiastic about your idea and 2) framing the idea in a way that is meaningful to your customer, and helps them understand how it matters to them. You can do this using tools mentioned earlier in this section--research their problems and challenges and present your idea as a solution.
