For me, the most important part of White Papers for Dummies is where you need to have a vision where there was none. Your product or company needs to differentiate itself by providing a new solution, or a new approach to a problem.
Traditional solutions do this wrong. Your offering does this instead. Clearly say what your company (or client) is doing and why your company does it best. You can prove through statistics and research. Sum up the problem, show how the competing offering doesn’t work, and then show your new and improved solution.
In a problem-solution paper, don’t mention your solution until the very last minute. This may sound counterintuitive, but the reason is to promote you as a trusted advisor and expert on your area.
