In a regulatory submission, document consistency is an important detail. A sub mission often has tight timelines and many writers and reviewers involved, but the goal should always be a submission that speaks in “one voice”. Utilising a consistent quality control (QC) reviewer throughout all documents of a submission can provide a significant benefit by ensuring accuracy in data presentation, style, and content across multiple deliverables. When a QC reviewer has a deep familiarity with the content and the team, inconsistencies in messaging are avoided, which can lead to submission documents being ready for review and approval.
