A strong project director can help influence a grant decision. Describe for the reader your plans for administering the project. This is especially important in a large operation, if more than one agency is collaborating on the project, or if you are using a fiscal agent. It needs to be crystal clear who is responsible for financial management, project outcomes, and reporting. Including an evaluation plan in your proposal indicates that you take your objectives seriously and want to know how well you have achieved them.
Evaluation is also a sound management tool.
Like strategic planning, it helps a nonprofit refine and improve its program. An evaluation can often be the best means for others to learn from your experience in conducting the project. There are two types of formal evaluation. Either or both might be appropriate to your project. The approach you choose will depend on the nature of the project and its objectives.
