Alternative controls and control plan

how can I handle the alternate process control method? within the "normal" control plan? or make another control plan?
If I use the normal control plan, have a mark an any way the alternate controls?

Answer:

The organization needs to identify, document and maintain the alternate methods for process control and get approval from the customer for these controls. The list of alternate process control methods should be referenced in a control plan, so you do not have to create another control plan, just include in existing one references to the alternate controls.

Since alternate controls are used incidentally and not on the regular basis (the standard requires organization to return to the standard process as soon as possible), the alternate controls should be distinguished in some way from the regular controls in the control plan.
