Correction in action. Essentially, if there are problems, drifts, or some other deviations, the operator is immediately advised of the situation through the activation of a red light. The operator can then query the system to determine the location of the problem and its possible cause. The basic format is monitor, detect, alarm, analyze, solve, implement. The fundamental objective is to reduce response time to process deviation.
People can correct the problem right away.
There are more variables than they thought there were. You really need a person in the loop to find out what caused the variation. One issue that Layden and Pearson are very wary of is setting off false alarms. RQM is designed to provide alarms and reports with the appropriate detail to the appropriate levels of personnel, whether it's the operator, the manager, or the people responsible for process improvement. Looking for six sigma.
