ll improve, examine the data to determine possible improvements, determine how you will measure the improvement, establish a target, and decide who will be involved in the improvement effort.Do. In the do step process improvement is implemented?often as a trial run. Data is collected before, during, and after the improvement.Check. In this step the pre-improvement data is compared to the post-improvement data. This analysis provides information about whether the root cause of the unwanted variation has been corrected.Act. The act step uses the analysis from the check step to determine the next action. If the root cause was found and corrected, the improvement would be standardized to ?hold the gain? and the cycle would start again with another process. If the root cause was not corrected, if the original target was not reached, or if there is room for further improvement, the cycle would begin again.1Principle 7 ? Fact-Based Decision MakingEffective decisions and actions are based on the analysis of data and information.Management by fact is one of many management concepts to teach managers to prevent management by "opinion". Facts are unknown until they are established through the collection of measurement data. This collection is done by using at least one of the 8 tools of quality. These 8 tools are: Flow chart, tally chart, pareto chart, cause and effect diagram, scatter diagram, histogram, run chart, and control chart. The analysis of relevant data allows informed decisions to be made and significantly reduces the risk for decisions based on opinion. Performance and data are often viewed as just numbers. However, performance can be improved by using data. Decisions and actions should be based on the analysis of data and information to improve results.1Principle 8 - Mutually Beneficial Supplier RelationshipsAn organization and its suppliers are independent, and a mutually beneficial relationship enhances the ability to...
