Electronic Logbook (eLog™)
Paperless computerized logbook platform capturing chronological cleanroom area access, equipment cleaning, operational runs, and maintenance events under 21 CFR Part 11.
Governing Pharmacopeial & cGMP References
Why Auditors Frequently Issue 483 Observations in this Area
- •Reliance on Uncontrolled Spreadsheets & Paper Sheets: Standalone calculation sheets lack 21 CFR Part 11 electronic signatures and cell-level audit trails.
- •Retrospective or Delayed Data Entry: Data entered hours or days after laboratory execution violates ALCOA+ contemporaneous recording principles.
- •Superficial Root Cause Determinations: Closing quality deviations or test failures without rigorous 5-Why or Ishikawa fishbone verification draws immediate investigator scrutiny.
- •Shared Credentials & Unrestricted Privileges: Operators or analysts utilizing generic logins or possessing database update rights without secondary sign-off.
5-Point Audit Readiness Checklist for Electronic Logbook (eLog™)
Audit Trail Completeness & Computer Clock Sync
Verify that all system transactions capture user ID, UTC timestamp, reason for change, and previous value synchronized via Network Time Protocol (NTP).
Access Control & Segregation of Duties
Ensure system administrators cannot edit or delete analytical records, and analysts cannot approve their own test calculations.
Automated Boundary & Tolerance Interlocks
Verify that out-of-specification results immediately freeze batch release workflows and trigger mandatory Phase 1 investigation forms.
Standardized Calculation Verification
Ensure all mathematical formulas (potency factor, dissolution Q, water content F) are governed by pre-validated system scripts rather than manual operator math.
Periodic Audit Trail Review Records
Maintain verifiable evidence of regular, risk-based audit trail reviews prior to Qualified Person (QP) or QA batch certification.

Frequently Asked Inspection Questions
What is eLog™?
Paperless computerized logbook platform capturing chronological cleanroom area access, equipment cleaning, operational runs, and maintenance events under 21 CFR Part 11.
Which official standards cover eLog™?
Electronic Logbook (eLog™) is referenced in US FDA 21 CFR §211.67 (Equipment cleaning and maintenance); EU GMP Annex 1 (2022); EU GMP Chapter 4. Replaces vulnerable paper binders on shop floors. Enforces deterministic status lifecycles, cleaning hold-time expiration countdowns, and continuous Landscape A4 audit registers for audit presentation.
How does Novaqis eLog™ apply eLog™?
Novaqis eLog™ features a deterministic 6-state FSM, automated cleanroom containment cascading, dirty/clean hold-time background countdown daemons, and strict Return-to-Dirty maintenance rules. Novaqis eLog™ can be deployed on-premises or in a customer-controlled private cloud.
Related Regulatory Standards in Facilities, Cleanrooms & Equipment
Cleanroom Classification (Grades A, B, C, D)
European and WHO GMP environmental grading system defining maximum allowable airborne particulate concentrations and microbiological limits for sterile drug manufacture.
Cleaning Hold Time Validation (Clean & Dirty Hold)
Validated time limits establishing how long equipment can remain dirty before cleaning (Dirty Hold Time) and how long it can remain clean before requiring re-sanitization (Clean Hold Time).
Return-to-Dirty Maintenance Rule
Quality safeguard requiring that any piece of equipment subjected to mechanical intervention, calibration, or maintenance must automatically transition to 'Dirty' status.
