From Wikipedia

Corrective action

A corrective action is a change implemented to address a weakness identified in a management system. Normally corrective actions are implemented in response to a customer complaint, abnormal levels of internal nonconformity, nonconformities identified during an internal audit or adverse or unstable trends in product and process monitoring such as would be identified by SPC.

.

## Examples of corrective actions

• Error Proofing (Poka yoke)
• Visible or Audible Alarms
• Process Redesign
• Product Redesign
• Training or enhancement/ modification of existing training programmes
• Improvements to maintenance schedules
• Improvements to material handling or storage

In some cases a combination of such actions may be necessary to fully correct the problem.
