As you prepare to present your project, there are some key factors to keep in mind with regards to both presenting the project itself and presenting to an audience overall. When presenting your project, it is important to keep in mind that you are the expert and this is what you were hired to do, as Monteiro (2014) puts it "Your client hired you because you are the expert at what you do. They are the expert at the thing they do." Be confident in your project, and also do not allow (in a respectful manner) clients to request or debate things that you know to be infeasible. It is important to leave the client with reasonable expectations. This may not always be an easy conversation to have, but if done respectfully is a productive one. During your presentation, be confident in your product and it's possibilities for the client. Owning the room and showing confidence will help to make the client feel that they can trust you and that your product is strong.
As far as presenting to an overall multi-level audience goes, there important tactics to keep in mind while preparing a presentation. Your audience for your presentation is taking their time to watch your presentation. It is important that you relate your presentation and product to them and make sure they know that it was not a waste of time and that your product relates to them. Additionally, keep in mind that your audience will be varied in understanding levels. It will be inevitable to have to touch on some more technical concepts that may be harder to understand, however they should be avoided or simplified when possible. It is important that you do not leave certain audience members extremely confused. For example, I went to a conference a few months ago and in some of the presentations I felt that they were much too technical for me and I would end up lost within a few minutes and lose interest in the presentation.
Overall I feel the three most important ways to make a successful presentation to a multi-level audience are as follows. The first one is to remember that you are selling your product, be positive and confident and sell it to your audience. The second step is to keep it simple, do not lose half your audience by making the presentation too complex, but make sure that you still are able to relay your message and sell your product. The last step is practice, most of us understand that "practice makes perfect" and it is important to practice all the parts of your presentation to make it feel natural. There will inevitably be curve balls thrown at you with question or scenarios you did not expect, but with adequate practice these will be easier to tackle.
Get up, stand up, and fight for your product!
It's important to be able to simplify your presentation, if you can't then maybe you should understand your own product better
