    About this ebook

    For the past decade, process validation issues ranked within the top six of Food and Drug Administration (FDA) form 483 observation findings issued each year. This poses a substantial problem for the medical device industry and is the reason why the authors wanted to write this book. The authors will share their collective knowledge: to help organizations improve patient safety and increase profitability while maintaining a state of compliance with regulations and standards.

    The intent of this book is to provide manufacturing quality professionals working in virtually any industry a quick, convenient, and comprehensive guide to properly conduct process validations that meet regulatory and certification requirements. It will aid quality technicians, engineers, managers, and others that need to plan, conduct, and monitor validation activities.

      Preface

      The intent of this book is to provide manufacturing quality professionals working in virtually any industry a quick, convenient, and comprehensive guide to properly conducting process validations. Although not the primary focus of this book, software validation requirements are briefly discussed. The reader must keep in mind that validating software can be extremely challenging and that some of the tools and techniques presented for process validation may not be applicable to software validation.

      Additionally, this book is intended to provide both background on and the requirements necessary to performing process validations that will comply with regulatory and certification body requirements. It is the authors’ contention that decision making on and evaluation of process validations should be done in the context of a systems approach.

Lastly, I would like to acknowledge the patience of my wife Dawn and my sons Jack and Sam, which allowed me the time to research and cowrite Practical Process Validation.

      Bob Mehta—I was inspired to author this book when providing services as a consultant to my pharmaceutical, biotechnology, medical device, active pharmaceutical ingredient, dietary supplement, and food clients. I would like to thank my wife Nina and my son Jay for their love and support for the past several decades, including my time authoring this book. I would like to recognize my friend and colleague Mark Durivage, author of several books and ASQ Fellow, for coauthoring this book.

      Chapter 1: Introduction

      This book was written to assist quality technicians, engineers, managers, and others that need to plan, conduct, and monitor validation activities. To that end, the intent of this book is to provide the quality professional working in virtually any industry a quick, convenient, and comprehensive guide to properly conducting process validations that meet regulatory and certification requirements. Both authors currently work in the medical device industry; however, the concepts presented in this book are designed for a broader audience.

      This book provides an introduction and background to the requirements necessary to perform process validations that will comply with regulatory and certification body requirements. It is the authors’ contention that decision making on and evaluation of process validations should be done in the context of a systems approach.

      From 2006–2015, process validation issues ranked within the top six of FDA form 483 observation findings (see Figure 1.1) issued by the Food and Drug Administration (FDA) each year. This poses a substantial problem for the medical device industry and is the reason the authors wanted to write this book and share their collective knowledge: to help organizations improve patient safety and increase profitability while maintaining a state of compliance with regulations and standards.
