Coca cola chairman and CEO E. Neville Isdell knows that the best companies embrace their mistakes and learn from them. That’s why Isdell doesn’t mind rhyming off the list of Coke’s failure over the years. In fact, he is keen to convince employees and shareholders that he will tolerate the failures that will inevitably result from the bigger risks that he wants Coke to take. At the same time, say analysists, balancing a learning culture with a performance culture is a perennial challenge. Intuit, the tax software company, thinks it has a solution. When one of its marketing strategies recently flopped, the company celebrated the failure and spent a lot of time dissecting it.
