Every grant proposal needs a clear statement of need or a problem statement. If there is no need to address or no problem to solve, there is really no need to set up a program or project. And, therefore, no need for funding. Identifying the need or problem is the first step in developing your program and is one of the first things a funder will want to know. Funders want to help solve problems, whether they are community related or global in nature.
Your needs statement should clearly define the need as well as what population has this need. However, this is only the first step. You must also back your need or problem statement up with facts, data and stories. It is not enough that you think there is a need. You have to do your research and make a case to funders that you have a need worth funding. Clearly define the need your audience has and back it up with facts and data.
