Knowledge Hub
A structured library of practical guidance across GMP compliance, investigations, documentation, audits, supplier quality, and risk-based decision-making.
VerethiQ organizes pharmaceutical quality systems into six connected domains to support clearer execution, stronger compliance, and better operational decisions across regulated environments.
WHO GMP: Structure & Focus
WHO GMP provides a global reference framework for pharmaceutical quality. This article explains its structure, regulatory role, and how it aligns with FDA and EU GMP expectations for international manufacturers.
EU GMP Annex 1: Key Updates
EU GMP Annex 1 introduces strengthened expectations for contamination control strategy, environmental monitoring, and sterile manufacturing oversight. This article explains the key updates and what they mean for inspection readiness.
US FDA vs EU GMP vs PIC/S
Global manufacturers must navigate FDA, EU GMP, and PIC/S frameworks. This article explains their structural differences, inspection styles, and how harmonized principles shape compliance expectations across regions.
Post-Implementation Verification
Post-implementation verification confirms that approved changes achieved intended outcomes without unintended risk. Learn how to structure monitoring and meet inspection expectations.
Writing Good Change Control Justifications
A change control record is only as strong as its justification. Learn how to write clear, risk-aligned justifications that address validation, training, and regulatory impact.
Risk-Based Change Control Assessment
Risk-based change control ensures that validation, training, and regulatory actions are proportionate to impact. Learn how to structure defensible change risk assessments in GMP systems.
What Belongs in Change Control
Not every modification requires formal change control. Learn what belongs in GMP change control, how to assess risk, and what inspectors evaluate during review.
Data Governance in QC Labs
QC laboratories generate decision-critical data. Learn how governance controls, audit trail review, system configuration, and oversight practices ensure reliable and inspection-ready laboratory data.
Stability Studies Explained
Stability studies support shelf-life assignment and ongoing product quality monitoring. Learn how stability programs are designed, trended, and evaluated during GMP inspections.
Method Validation Basics
Analytical method validation ensures reliable and accurate results in GMP laboratories. Learn core validation parameters, documentation expectations, and common inspection findings.
Out-of-Specification (OOS) Investigations
Out-of-Specification (OOS) investigations require structured Phase I and Phase II evaluation, controlled retesting, and documented root cause analysis. Learn regulatory expectations and common inspection findings.
Control of Non-Conforming Product
Non-conforming product must be segregated, investigated, and dispositioned through a structured GMP process. Learn regulatory expectations, rework considerations, and common inspection findings.
