Mistakes As A Source of Innovation
Effective leaders adhered to an unalterable expectation that mistakes and failure need to be an acceptable part of the process of innovation. They opposed "zero tolerance for mistakes" policies, many of which are still being practiced in many companies today. They considered these to be hindrances to innovation.
"It's easy to believe that Jeff Bezos is one of the great innovators. But that's not exactly the case. His rise into Fortune 500-dom actually has little to do with innovation and more to do with iteration. If anything, Amazon demonstrates how a cutting-edge Internet company - of all things - can succeed slowly. The trick is taking a million tiny steps - and quickly learning from your missteps." 
The mega-inventors of the 19th Century are also prime examples of this philosophy. "[George] Westinghouse (Westinghouse) built on his engineering skills, learning how to design and evaluate industrial trials. Time after time he turned trial failures into commercial successes. Even his competitors hailed his problem solving skills..."  "[Thomas] Edison (Edison Electric) viewed even disasters as an opportunity for learning. On one occasion his lab stove went out in the dead of winter, causing an assortment of expensive chemicals to freeze. On another occasion unprotected chemicals were damaged by sunlight. Instead of bemoaning the losses, Edison put aside all other projects to catalogue changes in the properties of the bottled substances... 'He knew how to turn lemons into lemonade.' " 
Walt Disney (Disney) took a proactive approach toward mistakes. "Walt found a way to push improvement without laying blame. [He] take(s) a look at what [someone says]... not glossing over a problem with the gag. He implicitly acknowledges it could be better. But rather than indulge an employee's criticism of another worker, he demands a positive, forward-thinking attitude - 'what we can do to make it better...' Walt kept employees engaged and contributing by not shooting down suggestions, but instead steering employees toward improving their ideas... Walt's approach to suggestions as the difference between responding 'Yes, if...' or 'No, because...' " 
As Sam Walton grew Wal-Mart into a retailing giant, he realized that "not all of his ideas worked. The minnow buckets didn't sell. People in Wisconsin didn't go for his Moon Pies. But when he saw he was wrong, he admitted his mistake and went on to try something else. And he wanted his associates to be the same way. He'd get them together on Saturday mornings to share their success and admit their failures. That culture of candor produced a great environment to capture ideas. It helped that he had 'very little capacity for embarrassment.'"
