Logic Model Types and Samples

Logic models come in all shapes and sizes. They range from simple to complex, small to large, and visual to textual. A logic model is a tool to help you get where you want to go, to convey how actions lead to desired results. The logic model is not an end in itself. It’s important that you use the approach that works best for you, your program, and your organization. Here are some general guidelines.

Ideally a logic model is:¹

• Contained within a single page
• Detailed enough to be easily explained and understood by others (but not too detailed).
• Divided into key parts or phases

So, what will your logic model look like? While it largely depends on why it’s being created, who is creating it, and who will use it, there are generally two styles: flow charts and tables. Before you build your logic model, click on the table and flow chart below for a tobacco control sample of each logic model type.

Once you decide what type of logic model you want, you are ready to start putting it together.
