Strategy to Quality
As an organization we can conceptually see where we want to be. We want to be free of errors that can be prevented. But before we can attempt to devise a strategy to get there we must do two things. We must do an analysis of the external environment that may be contributing to quality problems, but we must also to an internal environment analysis to see where we currently are.
You may have heard the phrase, "what you can measure, you can manage." Focusing internally on the organization would be the first step I would take. Start to find ways to improve the detection and reporting errors. Begin to establish a culture that sees errors as a way to improve and not a fear of reprimand. When you begin to understand the situation you are in, then we can begin to devise a strategy to remedy it.
