Rolly, your people-focus on reliability improvement and your commitment to helping people grow through improving their understanding of equipment and of themselves come through loud and clear in the book. The workplace stories you tell will resonate with people working in operations and maintenance in every industry. I very much like that you have provided practical answers with explanations and examples of how companies can move up the path to world-class maintenance performance. You have written about TPM, RCM, and RCA with great passion and an obvious depth of knowledge and experience. I’ve learned much more about the right way to use those tools by reading your book than I ever understood before. There is no doubt that the World Class Maintenance Management - The 12 Disciplines book will become a well-thumbed reference book for me. Rolly, I’ve been fortunate to come across you and value your honest perspectives and insights on doing maintenance right. I share your desires for what maintenance can become and do for a company and hope that we can combine our efforts in the future. 

This new book published in May 2020 is by far the most comprehensive maintenance management book written to date. That includes my Handbook of Maintenance Management. In 344 pages he lays out the history of maintenance management and the state of the art today. Rolly has deep experience and understanding in both RCM and TPM (an unusual combination) which adds depth to the discussion. He includes a detailed and practical glossary of keywords and their meanings. I want to make a few specific points. The assessment tool is great, and I will definitely upgrade my own assessment tool with his improvements. It covers all aspects of managing maintenance. Asset management: This is one of the best introductions to asset management and detailed rundown of ISO 5500X I've read. It shows through examples of how asset management can help the organization's effectiveness. Life cycle management is certainly part of asset management. In this case, the life cycle discussion shows definitively how most of the reliability is not under the control of the maintenance function. He says that reliability is a company's responsibility. Good graphics on the iceberg of costs to own and run a machine. Good maintenance practices may require a change in the corporation. The section on change management is well thought out and complete. Congratulations on publishing what will become the standard text in the field.

This book contains significant and relevant theory and idealism. I never read this kind of book before but it hits the core value of TPM. It is indeed maintenance quite necessary in any kind of manufacturing company. I salute for all technicalities which I don’t know it comes from before, I have learned a lot from this book. As technical personnel, I can say that it’s very much informative and vibrant. It makes a lot of sense in dealing with the alternative way of maintenance. All throughout, I was amazed by the author’s knowledge. Proud being a Filipino. Thank you for sharing this kind of book with us the author is really a mastermind on this TPM world. I absolutely enjoyed reading it even though I’m not really a reading enthusiast. I miss the Rolling Stone part which you gave the color on this book. Kudos Mr. Rolly Angeles for a good job. I now truly understand and felt being one of the maintenance team. This book has a heart and is very lively. I hope you continue to spread the meaningful story of the maintenance people. We owe you all the knowledge and being a part of this team review. Congratulations Mr. Rolly this is a heck of success. Thank you. 

First I want to thank you Mr. Rolly for giving me this very rare opportunity to comment in a book and have my comment in print. At first, I was wondering where would this book lead me? Your quote “changing a system means changing a culture” captured my attention. So as I read, I already knew I need to finish reading this book. I can relate to most of what was illustrated, stated, and example in this book. They’re all true and happening. A reality. I dreamed of having a kind of maintenance organization such as those described. My only worry is that I am not in the position to implement such. It is true that this kind of approach should be top to bottom, no support from upper management means you’ll end up to nothing. I am a maintenance guy and proud to be one. But it is great to know somebody that dedicates too much time and adheres to improve the lives of maintenance people like Rolly Angeles.
