Jeffrey Liker, Mike Rother
"a large survey conducted by Industry Week in 2007 found that only 2 percent of companies achieved their anticipated results... When we look at lean in this way it is not only a set of techniques for eliminating waste, but a process by which managers as leaders develop people so that desired results can be achieved, again and again. That means coaching people in practicing an improvement kata every day."
