One thing you should know about program evaluators is that they like their logic models and theories of change.
Over last 13ish years I’ve drawn over 25 comics on the subject. And as long as I keep cartooning, I’ll likely create a bunch more. In today’s blog post I’ll share the top 5 crowd favorites.
Let’s start my latest.
Two Theories of Change
In the last 5 days since I posted this one on LinkedIn, this comic has received 174 reactions and been seen on timelines over 12,000 times.
What that means to me, is that people relate. Things change, and your theory of change has to keep up. There is also a point here about changing expectations.

Baby’s First Logic Model
This comic started as a onesie for a pair of evaluators expecting their first child. It is still a onesie you can buy on RedBubble. But the cartoon itself is stand alone, and fits just as well in a presentation deck as it does on your kiddo.

Simplified Logic Model
This comic is actually one of a set of three comics I drew all the way back in 2012. And the original post on How to Not Really Evaluate is still live. But this comic stands out because of its simplicity and absurdness. It also rings a little too true for too many people.

Logic Model Repair Shop
Some models are simple. Others, not so much.
This cartoon has been a favorite for the people who really like talking about systems change. It’s also a good way in to start talking about complex programs.

Zombie Evaluator
This one here is one of my favorites. It’s more about intended outcomes than it is about logic models or theory of change, but it does have that eat brains leads to question mark slide. Which I would say is a kind of start to a logic model.

Want to see 20 more logic model and theory of change comics?
I just put up my Ultimate Logic Model & Theory of Change Collection on Redbubble. It includes these 5 along with twenty more that I’ve drawn over the years. Any of my patrons at the Presenter ($5) or Support Club ($10) level will have free access.
But if you don’t want to deal with ongoing membership, you can also purchase the collection with royalty-free use for a one time payment of $10.
