Who is the audience? Would you present your material the same to a group of potential retirees as to a large enterprise or a group of investors? Establishing a sensible flow to your message is key to building an engaging presentation.
Large enterprise: Large organizations tend to move slowly. After all it's a big ship to steer. This does not imply that you need a large and slow presentation. Quite the opposite is true. First, you must ease them into the idea that your organization is already worth a partnership of sorts. Convince them that you are good, have done well, and will continue to do good. Your value proposition comes near the end of the flow for this audience.
Investor group: The make-up of the investor audience is usually one short on impatience. They want to understand quickly what your business is offering. You must first establish the market space of operation, what overall percentage of the market you will obtain, and translate that into revenue. Flow with this audience is complicated because your audience is wearing two filters, one as the investor in your business and one as the potential end user. Address both.
Small group or company: This audience is usually the least receptive of your message. They are limited severely on time; however they will spend more time if there is a benefit that can help them. Therefore you need to establish your value proposition upfront (nearly) to grab their attention. Whereas this approach wouldn't work with large enterprise because they might not believe your company is worthy yet, the smaller organization or group wants you to get to the point...faster.
There are many more audience categories that require attention to special flow of your presentation message. Pay attention to your group and seek professional help from a presentation company.
