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.
QUICK REFERENCE
GMP & Quality Glossary
Use the glossary for concise, practical definitions of key GMP and quality system terms used throughout the VerethiQ Knowledge Hub.
Fishbone Diagram in GMP Investigations
Learn how to use a Fishbone, or Ishikawa, diagram in GMP investigations, including how the 6Ms translate into GMP categories, when to use the tool, and how to connect possible causes to evidence.
5-Why Analysis in GMP Investigations
Learn how to use 5-Why analysis in GMP investigations, including when to start with it, when to switch methods, how to ask stronger “why” questions, and how to avoid stopping at human error.
When Root Cause Analysis Goes Wrong
Learn why root cause analysis can go wrong in GMP investigations and how weak causal logic, premature conclusions, unsupported human error claims, and misaligned CAPA can affect investigation defensibility.
Human Error Reduction Techniques
Learn practical human error reduction techniques for GMP investigations, including procedure clarity, prompts, verification controls, workflow design, targeted training, and effectiveness checks.
Cognitive Bias in GMP Investigations
Learn how cognitive bias can affect GMP investigations, root cause analysis, CAPA decisions, and closure rationale, and how QA reviewers can challenge assumptions with evidence-based questions.
When CAPA Is Not Required
Learn why CAPA may not be required for a deviation and how to document correction, containment, impact assessment, recurrence review, and closure rationale.
CAPA Action Types Explained
Learn how containment, correction, corrective action, and preventive action serve different roles in GMP investigations and how clear CAPA action types support stronger closure decisions.
CAPA Verification & Closure
Learn how to verify CAPA implementation, distinguish verification from effectiveness, and close CAPA records with clear rationale, evidence, and controlled follow-up.
Writing Effective CAPAs
Learn how to write CAPAs that connect to the supported root cause, address recurrence risk, define clear actions, and support defensible GMP investigation closure.
CAPA Effectiveness Checks That Work
Learn how to design CAPA effectiveness checks that confirm whether the action actually improved control, reduced recurrence risk, and supports defensible investigation closure.
When CAPAs Do Not Match the Root Cause
Learn how to identify CAPA plans that correct the event but fail to address the supported root cause, leaving recurrence risk active.
Human Error vs System Error
Learn how to distinguish human error from system error in GMP investigations so root cause conclusions and CAPAs are supported, specific, and defensible.
