Corrective Action Process Locate and document the root cause of the nonconformity. Scan the entire system to ensure no other similar nonconformity could occur. Analyze the effect such a nonconformity may have had on a product or service produced before the nonconformity was discovered, and take action appropriate to the severity of the situation by either recalling the product, notifying the customer, downgrading or scrapping product.
Establish thorough follow-up to ensure the correction is effective and recurrence has been prevented. Preventive Action Process Take proactive steps to ensure a potential nonconformity does not occur. Employ process and system analysis to determine how to build in safeguards and process changes to prevent nonconformance.
For example, use a failure mode and effects analysis to identify risks and potential deficiencies and to set priorities for improvement. Developmental Action Process Treated as Preventive Actions Initiate an improvement project, with project plans, justification for planned expenditures, resource controls and evaluation. Contain a related series of actions, often separated by long periods so you can wait and see progress and results.
Use a variety of appropriate disciplines at different times during the project. Establish a means for communicating what has been done and what has to be done to facilitate communication about changes to project team members.
Include a clear trail of actions taken and decisions made to substantiate the decision to proceed, document lessons learned and avoid needless reinvention on future similar projects.
It is a solution. This is because corrective and preventive must be actions taken towards preventing a nonconformity from happening, not fixing the nonconformity itself.
It is important not to confuse these actions as solutions. Notice how buying a phone case is both a part of preventive and corrective action? As long as the solution prevents recurrence or occurrence, there is no one action that exclusively belongs to either preventive or corrective. Corrective and preventive actions are meant to stick. They are solutions that need to be carried out long-term. One way of ensuring continuous improvement through corrective and preventive action is to focus on the check step of the plan-do-check-act PDCA cycle.
It may involve changing the way something is done or the way something is made. Corrective Action is the act of taking corrective measures to prevent re-occurrences of a problem. Corrective Action starts with locating the root cause of the problem, and then taking necessary actions to eliminate the root cause of the problem. It is performed after the occurrence of a defect. Preventive Action is an activity designed to prevent a future or potential defect from occurring.
It is performed before the occurrence of a defect. ISO defines the correction as follows: Corrective Action: Action to eliminate the cause of a nonconformity and to prevent recurrence.
