Why are the Reasoning Backwards Tools so fast?
The weak link in most improvement processes is their inability to identify root causes quickly. The Reasoning Backwards Tools address this weakness. They begin by observing that a process is NOT flawed if it generates acceptable output most of the time. Some variation of inputs or process settings generates the defective output. The Reasoning Backwards Tools examine the very best and very worst outputs from the process to determine the patterns and consistent differences between them. This initial screening quickly generates clues about the root causes of the variation that exists, without interrupting normal operations. The Reasoning Backwards Tools “Listen to the Process” first. Root causes are identified in just days to weeks, and improvement is easy because the solution is tighter control of the existing process, not the development of a new process.
