Why does the Reasoning Backwards approach have such a big impact?
The Reasoning Backwards Tools do not change the original process, at least in the beginning, because the process works acceptably most of the time. Pareto’s Law assures that no more than 3 root causes are responsible for at least 90% of the defects that occur. The Reasoning Backwards Tools identify which 1-3 conditions have changed when the process produces defects. They show which variables are critical and must be controlled more tightly to prevent the defects from occurring. This approach often drops defects to zero. The Reasoning Backwards Tools look at ways to streamline or change the current process only AFTER the critical variables are known, and their tolerances have been adjusted to eliminate defects. Company culture is the other area where the Reasoning Backwards Tools have a big impact. These tools are so easy to use that everyone in an organization can use them and become an effective problem solver. As they do, they develop a strong sense of ownership and commitment. The t
