One of the first things we learn in programming is to decompose large problems into smaller parts. That divide-and-conquer approach can help us to assign tasks to others, reduce anxiety by focusing on one thing at a time, and improve modularity of our designs.

But there comes a time when things are ready to be hooked up.

That's where most developers go about things the wrong way.
