The Electronic Investigator Site File (eISF) Reference Model defines standard record names, attributes, and structure to electronically manage clinical trial records at a research site. The specific focus on electronic record management is the key differentiator of this initiative, compared to paper-based models.

This initiative delivers the following benefits to research sites that the [TMF Reference Model](https://tmfrefmodel.com/) provides for sponsors and CROs:

- Consistency of record keeping and organization
- Simplified reviews for sponsors, CROs, auditors, and inspectors
- Simplified exchange of records with sponsors, CROs, and IRBs/IECs

The eISF Reference Model is available in SiteVault. Veeva engages its SiteVault customers, research site stakeholders, and other reference model stakeholders to evolve the model toward becoming a standard that’s used at clinical research sites around the world.
