In Electronic Data Capture (EDC) systems, user roles are defined based on the functions and permissions required for specific study tasks. The most fundamental and universally applicable roles are Data Entry (performed by site staff) and Data Review (performed by monitors or data managers).
According to the GCDMP (Chapter: Technology and Electronic Data Capture Systems), defining user roles involves:
Assigning functional access levels (e.g., entry, review, query resolution).
Ensuring role-based security to protect data integrity.
Complying with 21 CFR Part 11 and ICH E6(R2) access control standards.
Options B, C, and D include functions (protocol review, analysis programming) not directly controlled within an EDC system.
Thus, option A (Data Entry and Data Review) correctly represents the two core factors considered when defining user roles.
