Build a culture of stopping to fix problems, to get quality right the first time.
I think the key message here is not that we should operate like a shop floor and allow any employee to stop a process at any time. Instead, there simply needs to be a culture that allows people to comfortably identify problems. It is in this type of culture where true forward progress often exists. When people actively look for problems for identification, they are actually looking for areas where processes can be improved. These are the beginnings of innovation which is where your company will be differentiated from all others.
