As mentioned before - be concise. The first 3 pages should include the following:
- A REALLY GOOD abstract. Again, you are earning their attention with that first impression!
- An Introduction section with subheadings. Make it easy for them to read and understand what you have to say.
- In the introduction section, lay out the following in subheadings: Problem; Technical solution; Team.
- Make sure the Team section explains why your team has the strongest technical chops to fulfill the requirements of this project. If there are gaps in your technical team - fill the gap! For example, you might include an academic authority in an area you don't have expertise in - and explain that you will engage them as a consultant on this project.
Once again, make it EASY for them to navigate the first 3 pages. Give them the information they want quickly. Do not put equations in the first 3 pages!
