I'm an investigator site and we work for many pharma sponsors/CROs. Some delegation logs from some sponsors/CROs have a separate section at the top of the log for only PI to sign and there is no column for authorization. Some logs need us to list tasks for PI but some logs have pre-printed saying "As a PI, I have responsibilities and oversee all tasks....." I consider it is appropriate to list PI in the delegation log but happy to hear other people's opinion too.
