Why Build a Logic Model?
Common reasons to build a logic model include the following:
- To explain why your program or planning process will succeed. By clearly laying out the tasks of development, implementation, and evaluation, a logic model can help you explain what you do and why you do it.
- To identify gaps in reasoning. By taking what’s in your head and putting it on paper, logic modeling can also help you discover any gaps in your reasoning or places where your assumptions might be off-track. The sooner these mistakes are discovered, the easier they are to remedy.
- To assist evaluation plan development and facilitate project reporting. Taking time to develop a logic model before implementing a program or activity not only makes explicit the intended outcomes and assumptions of the project, but also makes evaluation easier and more meaningful to key stakeholders.
