I’m going to show you an image and tell you a story, and you will believe it. You’ll believe not because I told you to believe it, but because you want to believe it is true.
The Story
This is a place where mankind has sanitized, homogenized, and developed using a rigid and typically unforgiving material; concrete. A downfall of concrete’s hard-line take on the world is that sometimes cracks form. Cracks that let the organic spurt through. Dirt and rain make their way down, plants make their way up, and we’re left with this analogy. Creative ideas can grow in restrictive environments.
And it is true. I’ve even written about it here. But there is caution to the tale.
The Balancing Act
Just because creativity can grow like a plant in concrete doesn’t mean we don’t have to nurture it. You can’t go laying concrete everywhere in your innovation and expect the good stuff to always break through.
There is a time to let things diverge and a time to let things converge.

Imagine creat be thought is like a rosebush. You nurture it and let it grow; branches twisting and turning in their own way. Some are full of thorns, while others yield the most beautiful and fragrant blossoms. You, as the gardner, have your choice of the best idea roses for your bouquet.
Now imagine that when the rosebush was very small, you had placed a funnel on top. Everything that the rosebush wants to do, must be forced up and out a narrow opening. It’s like the Highlander but for plants; in the end there can be only one blossom. The funnel converges too soon. The only divergence happens just above the root, but it’s not enough to allow a variety of blossoms because they’re all now competing to get out of the funnel. When you go to trim, you don’t get a choice. You get the one idea-bloom that managed to make it out of the funnel, and you’ll never know if it was the best you could have produced.
The Summary
Constraints and restrictions are still valid. We put up fences because we don’t want our rosebush growing into the neighbor’s yard. These restrictions come from your users (it needs to be mobile, it has to do [task] faster, etc). However if we don’t let solutions diverge from the root of the problem, we wont have a chance to converge them into the best bouquet of products possible.
