How can a company be so NUTS and be so successful?

Now, Southwest's secrets are out. Management consultants, Kevin and Jackie Freiberg, describe the inner workings of one of America's biggest success stories. They know Southwest, inside and out, having worked with the company for more then 10 years. Isn't it NUTS for a company to: avoid TQM, reengineering and the other management fads of the last 25 years, believe that customers come second, settle major legal disputes by arm wrestling, avoid formal, documented, strategic planning, spend more time planing parties then writing policies, make the "lone ranger" leadership mentality a thing of the past?
