“On this journey you learn to impose on yourself the same kind of disciplined adherence to process you now expect of operators in following their standardized work or standardized procedures. As you continue on the journey you learn to focus with near obsessive intensity on the processes in your system. You learn to trust that results will take care of themselves when you take care of the process.”
