This is my eighth on a series of books I wrote and am still writing, based on the original concept of my first book on World Class Maintenance Management, The 12 Disciplines, as shown on page 3 of this book. In as much as I can, I have written all my books in the simplest way to understand for the benefit of the readers. Here is feedback to one of my readers, which I truly value and inspire me to write more books about our common passion, reliability, and maintenance. Perhaps the reader would want to know what RSA is. The first and the last stand for my name, which is Rolly Angeles. The letter "S" is my middle name, or better yet, it also stands for Stones, which is my favorite band that I always featured and discussed in my previous books. This book is a collection of all my reliability and maintenance newsletters. I wrote, which I started from May 2007 until December 2020. It contains around 164 newsletters on different topics of our common interest, all about reliability and maintenance. The majority of these newsletters are included in my books based on their particular maintenance discipline. This is a supplementary book to my sequel on World Class Maintenance Management – The 12 Disciplines, unlike my other books specifically dedicated to a particular discipline on World Class Maintenance Management, which is why it is in series. This book covers all the disciplines into one reading. I have used most of these newsletters in my other books depending on the particular maintenance discipline it fits in. The chapters of this book are chronologically arranged according to the year the newsletter was written, starting from May 2007 to December 2020.
