RQA GLP Committee
This would not be acceptable under normal circumstances in a GLP environment. You need to consider the integrity of the data that will be generated. You need to know who carried out the work, who was responsible for setting it up, making changes etc. If this cannot be reconstructed, then you do not have the required controls in place.
You would need to conduct a Risk Assessment and mitigate as many of the issues raised as possible. You would need to include a lot of controls around who did what, when.
