The most significant difference in theData Manager’s rolewhen using anElectronic Data Capture (EDC)system is thatdata updates are implemented directly by site personnel(Option A).
According to theGCDMP (Chapter: Electronic Data Capture Systems), EDC technology shifts responsibility for data entry and correction from the sponsor or CRO to the investigator site, enabling real-time data entry and validation. This eliminates the need for double entry or remote data transcription, allowing Data Managers to focus onsystem validation, query management, and data quality oversightrather than physical data handling.
However, the EDC system still requires full validation (contrary to Option B). Metrics generation (Option C) and CRF tracking (Option D) are important but not unique to EDC-based workflows.
Thus, the correct answer isOption A – Data updates are implemented by the sites, reflecting the most fundamental operational shift introduced by EDC systems.
