Successful grant writing is a highly iterative, detail-oriented process. To craft a truly great grant proposal, you need to demonstrate to a potential funder how all of the parts of a grant application both fit together and affect one other.
To ensure a grant proposal is both logically and structurally sound, use a logic model (also called a theory of change) to demonstrate how all of the moving parts in a proposal work together to form a cohesive, measurable project. A logic model is a blueprint that evaluates and measures how certain assumptions, inputs, activities, and outputs (the process-focused components of your program or project) lead to the desired goals and short-, medium-, and long-term outcomes that will best serve the target audience and effect social change.
