I have been a lead auditor since 1994 and have been in over 100 businesses over the past 20 years and find that Corrective Action and Root Cause Analysis are still a foreign concept to most people who are tasked with answering a corrective action request.
The intent of root cause analysis and corrective action is to reduce the risk of an error being committed during a process. Poka-yoke is used in lean manufacturing to determine the root cause of a problem and to come up with a solution to eliminate the possibility of a problem occurring during the daily activities.
Types of Poka-Yoke:
One of Japan's leaders in lean manufacturing and mistake proofing, Shigeo Shingo, determined there were three types of poka-yoke (aids or methods) for detecting and preventing errors in a product/service process:
1. Root Cause: Process is such that physical attributes are hard to control. Corrective Action: The contact method identifies product/service defects by testing or inspecting the product or services physical attributes such as shape, size, and color.
2. Root Cause: Problem is dependent on focus of operator. Corrective Action The fixed-value or warning poka-yoke alerts the operator if a certain number of movements are not made or a mistake is about to be made..
3. Root Cause: The current process does not reflect the steps needed to meet the customer's requirements. Corrective Action: The sequence method determines whether the defined steps of the process have been followed.
If appropriate poka-yokes are implemented, mistakes can be caught quickly and prevented from resulting in errors. By eliminating problems at the source, the cost of mistakes is reduced.
