Logic models are one of those things that are great to have available when writing grants or engaging potential donors, but they can be a challenge to create. I think the process of putting together a logic model can be daunting. The details can feel overwhelming and complicated at first glance. In all actuality, logic models can actually simplify things, creating an illustration for the good results we see and why those good results occur. As the Fieldstone Alliance points out, the practical benefits of having logic models are:

1. They help you understand why something works
2. They tell the story of your program quickly and visually
3. You can apply the models theories to new and related problems

 
Fortunately, there are a lot of good resources available to provide some guidance.  When I created my 1st logic model, I used the Kellog Foundation logic model guide, and it served me well. It's still my go-to resource on the topic. However, I was pleased to see that the Fieldstone Alliance has a simple page about creating logic models, which serves as a great introduction.
