Published December 22, March 31, You may need to implement more than one interim containment action to fully protect the customer. An interim containment action can be any action that protects the customer from the problem. However, before you implement an interim containment action, you need to verify that the interim containment action will work. To verify the interim containment action:.
Conduct trial runs whenever possible. However, in some situations, your verification may simply be a matter of common sense. For example, if an interim containment action involves stopping the shipment of all products, you can be sure that customers will stop experiencing the problem. You and your team must consider all of the trade-offs connected to your interim containment action. An important part of implementing an interim containment action is planning how you will implement the action.
Isolate and verify the root-cause by testing each possible cause against the problem description and test data. Also isolate and verify the place in the process where the effect of the root-cause should have been detected and contained escape point.
The problem description should describe the problems in terms of what, where, when, and how big. The description should contain facts; such as observations and documentary evidence and not assumptions. All information must be gathered before identifying the root-cause can begin. Make sure both of the above factors are true before you move to the next step.
Consider any new information that the team may have gathered since completing the initial problem description. Once you have reviewed the problem description, you can begin a comparative analysis. A comparative analysis will help you identify relevant changes in a change-induced situation. Then you can reduce the number of possibilities that you must consider to determine root-cause.
If the problem is change-induced, the root-cause must be the result of a change relative to one or more of the identified changes. Any information you develop during the comparative analysis must be fact based, not opinion based and must be true only for the symptoms information.
Do not rule out any facts that might be valid answers. If it is a fact and it answers the question, write it down. Now that you have narrowed down the possible root-causes, you need to develop theories about how the problem occurred. Theories are statements that describe how a change may have created the problem. If a theory explains the problem, but lacks information necessary to explain why it happened, gather more data:.
The root-cause must explain all known data. Any theories that pass the trial run are the most likely causes. If only one theory passes the trial run then verify this theory as the root-cause.
However, more than one theory may pass the trial run. In those cases and when practical and feasible , collect and analyze any missing data for uncertain theories and re-examine information to resolve uncertainties.
There are several variants for applying corrective actions to problem-solving, but essentially, they all follow a common approach. The most popular of these is formalized under the ISO quality management system.
This system is detailed below. As highlighted, there are some variants of these steps refinements to suit specific industries or organizations. The steps may be a simple list or built into sophisticated software solutions. Like all tools, the value is in using them effectively. Simple tools in a craftsman's hand are better than complex software-based solutions that are not fully understood. If your organization is not using this methodology, then guidelines and checklists can be tailored to a company-specific format for the process when someone makes a corrective action request.
A popular alternative to the corrective action steps is the 8D Method for problem-solving. This was initially developed by the US Defence Department but was tailored for the automotive industry by Ford. The steps for this are shown in the diagram below:. This is a CAPA process built with Integrify's workflow automation platform , The process begins with the reporting of an issue with details and documentation and continues all the way through the investigation and corrections, including review and approval.
There are numerous examples of corrective actions in various industrial and business applications. These range from:. A corrective action process is a quality management methodology that allows for formal documentation and assessment of industry and business problems.
We recognize that the corrective action process provides a formal documented means of problem-solving. However, we should remember that solid, lasting corrective actions involve more than filling out a template but require disciplined, practical application of the process.
