QMS Certified Internal Auditor

Mastering Internal Auditing: A Practical Guide to ISO 9001 and ISO 19011 Compliance

Author: Dr. Mohamed-Ali Ibrahim

Introduction

Internal auditing is an essential part of an effective Quality Management System. It helps organizations assess compliance, identify risks, improve processes, address nonconformities, and maintain confidence in the performance of their management systems.

QMS Certified Internal Auditor is a comprehensive workshop e-book designed to develop the knowledge, competence, and confidence required to plan, conduct, report, and follow up professional internal audits.

The book focuses on the relationship between ISO 9001:2015, the internationally recognized Quality Management System standard, and ISO 19011:2018, which provides guidelines for auditing management systems.

Readers are guided through the complete internal-audit lifecycle, including audit preparation, defining objectives and criteria, selecting audit teams, conducting onsite and remote audits, gathering objective evidence, interviewing auditees, identifying nonconformities, preparing audit reports, managing corrective actions, and verifying their effectiveness.

The book also explains risk-based thinking, auditor ethics, confidentiality, professional competence, audit-program management, performance metrics, continual improvement, and emerging developments in internal auditing.

With structured chapters, practical explanations, case studies, questions and answers, and a detailed glossary, this book can be used as a professional reference, workshop resource, training manual, or certification-preparation guide.
