Overall, the majority of issues that need to be resolved are lack of details and clarity. You must define, in the most concise terms, the value and feasibility of your project to your perspective audience. To accomplish such a task, think more in-depth about and address each facet of your Final Project. I.e. anticipate and answer any questions that might arise before they are asked. Such a strategy places the constraints of the issue or query within the scope of the presenter (you), rather than the audience. Thus, do not allow your audience the leeway to construct an assumption or answer. Guide them at all times. In fact, you should be prepared for any and all questions. In other words, you should already know and understand the “inadequacies” of your proposal and be prepared to speak to them in your presentation.
