Once permanent solutions are in place, document the changes. In addition, all customers need to be informed about what actions were taken. In most cases, some type of training is required to institute permanent corrective actions. Training may be required to implement a product design or process change. In addition, implementation of the permanent actions may need to include the effect on design or process issues. In manufacturing, maintenance personnel often need to be informed of the changes.
Another important part is to correct the obvious. This includes correcting defective parts already produced, changing product design, changing tooling, reworking defective machines and/or equipment, revising ineffective operating systems or working with and/or replacing suppliers.
Contingency actions should be identified if for some reason the permanent actions cannot be implemented. For example, in manufacturing a recommendation to single source a part may be recommended. But, if one vendor is unable to meet the increased productivity alternate action is necessary. Contingency actions based upon risk assessment are essential to the success of permanent corrective actions for customer protection and problem solution.
