Correction vs. prevention

When there’s a deviation, you probably need to have a corrective action. However, you can also find the root cause of the deviation and have a preventive action to avoid the same problem in the future. Unfortunately, most people only correct the deviations and don’t put enough effort into preventing them.

If you must sacrifice one, sacrifice the corrective action rather than the preventive action; otherwise, you will be spending the rest of the project fire-fighting without enough time to do anything fundamental.

If you agree with this recommendation, maybe you can check to see whether you need to make it explicit in your methodology.
