The defects need to be fixed and the completion status of reported defects needs to be logged properly. After rework the work product needs to be labelled suitably.

Reviewer needs to ensure the verification of the work product against the reported defects.

Major or repetitive defects needs to be further analysed to determine the root causes.

Further to root cause analysis, action plans to prevent recurrences of the defects needs to be taken

Review parameters like review speed, review effectiveness etc needs to be analysed and compared against the goal set for those parameters. Further actions needs to be deployed based on the analysis. For more information please refer the post on Review Data Analysis

FCDL can be made taking review feedback from the reviewer. And FCDL needs to be continuously updated after each round of review. The key is to learn from faults and consciously avoid repeating them.

Trainings can be triggered to avoid repetition of defects or to improve the depth of review

Finally, it is important to ensure that the status of review, rework, corrective actions etc. is communicated to all stakeholders.
