He starts the article this way,

"Here is a quick way to judge whether your company will continue 
to be successful: can you tell your CEO that you spent the morning 
tinkering around with an idea? If the answer is yes, you are in 
good shape. If no, start looking for another job.

Successful companies know that the path to innovation isn't 
a straight line. Profitable growth is a messy, roller-coaster 
process that involves almost as many setbacks as victories. 
If you succeed in everything you do, you aren't aiming nearly 
high enough.

I get frustrated when companies talk and talk and talk about 
innovation, while simultaneously making it nearly impossible 
for their employees to tinker around. Tinkering is what drives 
innovation, not talking."

There is much that I agree with in Bruce Kasanoff’s article, but there are some big disagreements as well. In the spirit of lively conversation, here are my comments:

Bruce Kasanoff, you are correct. There are a few reasons why tinkering is so valuable: (1). You allow your brain to enter another state of being – it’s not linear, driven, goal-oriented. If you learn to recognize that “creative/tinkering” brain-state then you can enter it more easily and on-demand. The ability to move into and out of states-of-being is very valuable for serial innovators. You need to learn to develop that skill if you want to innovate reliably. (2). Developing your persistence ‘muscle’ is also vital to innovators because innovation generally takes effort and you cannot cave-in at the first obstacle. There are lots of reasons why innovators need to persist. It is a basic characteristic of great serial innovators.

I read a blog article at the Huffington Post by Judith E. Glaser called, “Innovate or Evaporate“. This is a good article about innovation,  but I have one disagreement her statements about fear limiting innovation. In a nutshell she says,

"When fear 'owns our brains' we cannot think creatively... All we think about is how to protect ourselves."

There are indeed processes that happen consistently within the human brain. We have responses to inputs that travel in ‘ruts’ or along strong synapse paths. In these cases inputs create a cascade of reactions. Fear can cause a cascade of reactions that does indeed ‘close down’ the creative parts of our brain and get us stuck in protection mode. But, and this is a big ‘but’, it doesn’t need to. A person can train their brain to respond differently to fear – interrupt the cascade – deflect the automatic response – and react more usefully and creatively. Serial innovators train themselves to be able to change states.
