Slide 6.26 requires the investigation of deviations and results of release testing after the completion of each significant step. Usually release testing and deviation investigations take longer than it takes to complete each significant step. Is it acceptable to include this documentation in a report after completion of the batch instead of after each significant step?
Yes, that can be done after the completion of the step. What Q7A tells you in Section 6.7, is that this should be completed before the release of the batch.
