Discipline is not so much a step as it is an outcome of strong leadership. A few years ago, I listened in disbelief as a senior manager from a national builder stated categorically that it was a waste of time to get suppliers and trades involved because he already knew all of his company’s problems and how to fix them. His only issue was getting his managers to do it. Set aside for a moment the sheer arrogance of his statement — the notion that he could know what 20 or 30 supplier and trade firms know — his statement indicated a clear lack of discipline in his organization. This manager presumed to have the solutions yet could not get his people to carry them out. It was obvious to everyone else that day where the real source of his problems lie. Discipline in the execution of the daily requirements to run a business within a culture of continual improvement is essential. Without it, everything you gained in steps 1 through 9 will come to naught.
