First, I want to thank you, Mr. Rolly, for giving me this very rare opportunity to comment on a book and have my print comment.  At first, I was wondering where this book would 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. This kind of approach should indeed 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.  From Darwin Abragante, Level 2 Thermographer, Analog Devices Gen. Trias, Inc.

This book is easy to read (take it from a selective reader), and the flow of thought is smooth – relatable; to maintenance, production, and quality people.  The book provides general and specific inputs to prepare a maintenance roadmap for an organization. The author, a maintenance guy, a facilitator, and a trainer shares his vast experience in the actual maintenance task, implementation of maintenance strategy, and analysis of maintenance management issues.  This book has a well-established link from the initial book that Rolly released.  The way the book was written is just like having Rolly in front of you, explaining with passion the different topics about maintenance strategy – book well written.  The TPM-PM implementation and TPM lessons shared by Rolly give the reader of this book a glimpse – guidance on what needs to be done plus the pitfalls that need to be avoided. As each organization forms and develops its own maintenance culture, this book is a good reference.  From Charles D. Mendoza, Sr. Quality Improvement Engineer/TQM/TPM, STMicroelectronics Inc.

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 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 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 to combine our efforts in the future.  From  Mike Sondalini,  Reliability Consultant, Lifetime-Reliability, Australia

This new book, published in May 2020, is 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 state of the art today.  Rolly has deep experience and understanding in 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 a 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 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.  By Joel Levitt, President of Springfield Resources and Book Author

Never accept failures in your plant. Troubleshooting and repair is no longer an effective strategy, In today's competitive world of manufacturing, the analyst find real solutions to their equipment problems. Remember that when our people become really good at repairing failures then something is wrong since they are doing it much too often but when we expect a different result from the same things that we are doing, it just ain't possible, the Chinese called this insanity.


Let me say off-the-bat that attending one of Rolly Angeles' seminars is the best thing there is. I, having over 20-years of experience in Engineering and Maintenance and having already attended numerous technical seminars, thought I already knew much there is to know about my field.  That is before I was fortunate enough to attend his seminar on 'World Class Maintenance.' There, I realized that there's still much to learn, especially if you hear the learnings straight from someone who has specialized in the field as Rolly Angeles has.  Having said that, reading one of Rolly Angeles's books, particularly his latest, 'Cutting-Edge Maintenance Management Strategies,' is the next best thing.  Similar to attending one of his seminars, reading this book will lead you to a paradigm shift.  You will never look at the field of maintenance the same way upon reading this book. Reading Chapter 2 of this book, where he elucidated on 'Breakdowns and Failures,' will set you off and get you going to finishing the book as you will start to realize that you have to unlearn some of your long-time thoughts and impressions on how to conduct your maintenance system. If there are two words to describe this book, it would be 'insightful and witty.'  I highly recommend this book, especially if you are in the field of Engineering and Maintenance as I am.  It is a highly-enjoyable, practical, and educational read. Certainly, it would be a highly valuable resource to anyone who strives to improve and upgrade his maintenance system.  From Arnaldo Ocfemia, RME, GREEEN ADP + AA, Engineering Director, De La Salle-College of Saint Benilde


Thank you for allowing me to review your new book to be published.  It is impressive, and you have taken pains to explain the fundamentals and important and useful information on practical problems encountered by Maintenance Engineers.  Rolly Angeles is a Maintenance and Reliability wizard.  He has dedicated his profession to training and implementation of TPM and RCM.  Brought out books on World Class Maintenance, TPM, and Reliability in the past.  Has once again published a book on Cutting-Edge Maintenance Management Strategies.  He has holistically addressed the prominent reasons which augment the reliability of assets by the interpretation of the facts like infant mortality, random and age-related failures.  He advocates that maintenance has to be a subject which is a profit center, and C-suite has to take cognizance of the fact that well-trained Maintenance Managers will be able to sustain the tremendous expectations, and it should be their topmost priority.  The present strategy to increase uptime should be by eliminating dominant failures by total eradication through Reliability solutions.  There needs to be a paradigm shift from reactive maintenance to proactive maintenance.  Most industries are still in the ambiance of reactive maintenance, which is a set-back.  Effective and efficient solutions can be achieved by treating maintenance not as a cost center but as a profit center.  Better maintenance results in more uptime, more throughput, lesser breakdowns, lesser failures, and finally, more profitability and ROI.  He is also encouraging industries to acquire the World Class Maintenance standard and presented a questionnaire for Senior Management to study, assess their existing status, and work towards attaining WCM.  The importance of preventive maintenance, which often gets abused, misused, or overused, and their consequences are highlighted.


Similarly, predictive maintenance and it's significance to the P-F interval is explained. The importance of Precision Maintenance, which should be taught to maintenance personnel, will help them to acquire the skills more briefly and also enable them to become proficient in PM, fixing random failures and infant mortality.  PM has been elaborately covered. Recommendations are made to set up a planned maintenance pillar before undertaking Autonomous Maintenance. MRO spare parts, economic order quantity have been covered with suggestions for improvement of equipment and with reduction of inventory levels. TPM and RCM have been covered elaborately.  Both complement each other, and integrating RCM into TPM methodology for a robust approach to maintenance has been explained.  Lastly, CMMS, EAM, IIoT, and industry 4.0, which are important for digital augmentation, have also been covered.  I wish him the best of luck in his endeavor and hope to see many Maintenance Engineers, Reliability Engineers, and Asset performance management personnel to benefit greatly from the valuable information available in the book.  For the first time, I have come across an author like Rolly, to have exhaustively discussed all points relevant to Asset, Maintenance, and Reliability.  From Sundar Kumar, Ex-General Manager

This portion is dedicated to the greatest band of The Rolling Stones, which started in 1962 and still together. What made them stick together after simply five decades of music, I simply can't say, as Keith Richards said in his book "Life. If I can excite Mick, then Mick can excite the world. Last 2012 they started celebrating their fifty-six years as a band.  They are considered the longest-running band on the planet.  What makes them great is their passion; as Keith Richard said in his book "Life," if I can excite Mick, Mick can excite the world.   This is a band that never split or separate, and they will be there together for life.

I hope you don’t mind if I use your life, of course, the part you shared with us and the ones you wrote in the book, as an example to our AM (Autonomous Maintenance) teams to encourage them to look beyond what they are capable of doing at this moment in their lives and of inspiring them to dream and grab every opportunity to learn and improve themselves.  The book simplified the concepts of maintenance to aid practitioners like us.  As I browse through the book, I can see that this is not just a technical book about maintenance, but a book about your passion, your life. Congratulations!  From Flordeliza V. Aldaya, TPM Chief Engineer, ST Micro-electronics, Calamba, Laguna, Philippines


I am already half-done reading your book, and I find it very, very useful. I was shocked, from a welder/mechanic's point of view, the explanations in your book, especially the metaphors, has accomplished in making me understand more easily what it is you are trying to convey. It should be a Handbook for Maintenance personnel and, of course, an eye-opener for the operations. Regards to Mang Tibo. Good day to you Sir.  From Julius Fungo, CE Casecnan, Nueva Ecija, Philippines


Hi Mr. Rolly, Hopefully, you still remember me. I am the one who gives you my thesis during WCM - 12 Discipline courses @ Eastin Hotel, Malaysia. Here I want to review the WCM Book. I already read the book twice. It really fills me with hope for the maintenance role to be outstanding. The setting for this book was perfect. Every discipline was made easy to grasp. It covers almost all dimensions of maintenance management. Without reservation, I heartily recommend this book.  Thank you.  From Khairul Haffiz Noriddin, a delegate from World Class Maintenance Training, Malaysia


Rolly’s book “World Class Maintenance Management” comprehensively explains the 12 Disciplines and provides a valuable reference for maintenance personnel. He has a dynamic, vibrant personality, which he uses to presents the knowledge and wisdom condensed in his book in interesting and dynamic ways. He has a broad knowledge of the field of Maintenance and operator involvement in achieving the greatest profitability of the production plant. Rolly is an excellent experienced trainer in Reliability and Maintenance Best Practice."  From Howard Witt, Maintenance Consultant from Australia

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 in 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 a success.  Thank you. From Wilma S. Magbujos, Process Technician, Transitions Optical Phil's Inc., Philippines


I have attended two of Rolly’s public training. The first time was for MRO Spare Parts Management.  It seems that I was transported to his world of World Class Maintenance. The second one was about Condition Based Maintenance. Though the stories and sidebars are the same as when I attended the first, I am still amazed at how he could relate all of his stories and connect them to the roles of Operation and Maintenance in any industry.  Being from the manufacturing industry for more than twenty-five years and being employed by four companies, I have often seen issues and the disconnection between operations and maintenance, over and over again.  The most common issue is moving forward, as heard from one qualified expert, which escapes my memory, and relating it with Operations and Maintenance is that “we are managing the present with the tools of the past and thinking about the future with the mindset of the past.”  Rolly’s book provides a wealth of wisdom and actual years of experience in the roles of operations and maintenance. This is mostly recommended to leadership, as this book shall serve as a guide and a template on how to move towards reliability.  The stories will definitely change our mindset and paradigm on the dealings and transactions of operation and maintenance.  The tools mentioned in the book shall guide us to the future with our ultimate goal of improving reliability. Be it the Japanese (TPM) or Western (RCM) style of maintenance model, the common denominator is the partnership between operators and maintenance.  A must-have book for industry’s leadership or, better yet, attend Rolly’s training. Congratulations, Mr. Rolly “Stones” Angeles!  From Rodel T. Domingo, Corporate Engineering and Maintenance Manager at Multiflex RNC Philippines, Inc. (URATEX).


Reliability – A Shared Responsibility for Operators and Maintenance is a powerful book that provides a significant fact of Operators and Maintenance relationships and how these two functions evolve into a team that works together to greatly improve the plant's reliability.  A masterpiece by Mr. Rolly would be a vehicle for cost-efficient operation in any Manufacturing Plants or industries. This book also includes a powerful tool to implement Autonomous Maintenance, Planned Maintenance, Reliability-Centered Maintenance, Root Cause Failure Analysis, and FMEA/FMECA.  Thank you very much, Mr. Rolly, for making our lives (Operators and Maintenance) more effective and efficient, especially for me as a Mechanical Maintenance Head; this book will shape not only me but my team into a World Class Maintenance.  From Marion Fajardo Gomez, Mechanical Maintenance Supervisor, Therma South Inc., Philippines


Congratulations, Mr. Rolly, for writing this book.  First, I would like to thank you for accepting me as part of the review team. I was very happy since I only heard of World Class Maintenance from my bosses, and only a few representatives were allowed to attend your training.  I only heard the echoed training, which is quite hard to understand.  I appreciate your choice of simple language in writing this book for easily grasping your point.  Reliability - A Shared Responsibility for Operators and Maintenance is enlightenment for industry putting maintenance dilemma into words.  The truth is, it is overwhelming that reliability should be a priority, which is not I used to hear from my 10 years of my industry experience as maintenance, but you explain it with examples that are easily understood.  Operators and maintenance working together will take a long journey of change. This change is hard to implement with the old mindset of operator and maintenance, especially in my plant where operators are just high school graduates, but with the current industry trend, hiring technical graduate operators, or at least the college level, I perceive it is doable. I hope and pray people will read this book, especially Top Management, so the operations will finally adopt this change.  From Janice Dacles Casas, Former maintenance at Cebu Mitsumi Philippines and Fairchild Semiconductor, Cebu Philippines

This training will help us since we target spare parts inventory reduction, especially for non-moving and obsolete materials and spare parts.  Sir Rolly made the topic very interesting by giving several examples and scenarios for us to simply understand the topic.  He has a vast knowledge and experience in maintenance, which he shared for this 3 days training.  I will surely share the knowledge I learned from this training.  From Reinalyn Unico, Process Development Specialist, Coca-Cola


I learned that to improve MRO warehousing, it needs to improve first both the inside and outside factors that affect storeroom management.  Proper coordination of maintenance people and operations, including warehouse, is needed to improve the MRO Storeroom Management of a company.  Learned new ideas on how to handle and store spare parts.  Help us to determine when to request a part.  From Adelfa Mormon, URC Sure Tolong

Attending this training educates us on the importance of having an MRO storeroom and spare parts management and apply this in the department step by step.  The training increased my knowledge of the value of this training.  It tackles a lot of issues that make improve my role as guardian of the store.  There are lots of improvements that can be imposed in our storeroom.  All critical parts should be identified.  The inventory system should also improve.  Most important is to manned the storeroom 24/7 to lower inventory discrepancy and avoid stock out.  From Andrew Jacob, Engineering Storekeeper, Philippine Bio Industries


There were so many learning's I have gained through this 3 days training.  This training tackles all the things we can improve in our maintenance and storeroom management to manage our spare parts optimally.  I know we can cascade all the learning's as well as the modules taught to us.  Rest assured that all lessons would be shared with the plant to have a good organization and collaboration for MRO Spare Parts and Storeroom Management.  From Jane Marie Lee, Franklin Baker


I have been involved in Maintenance for so many years and most of it in the Store Room and Purchasing Functions.  I agree with his list of the Top Problems on the MRO Spare Parts and Storeroom, as I have encountered most of them in one way or another. I have inherited many Non-Moving Spare Parts for our Legacy Equipment w/c account for nearly 50% of my Inventory. I would like to add one (1) problem to his list w/c I have encountered. Since most of the Maintenance Crew is new and without Proper Training, they will come to the Store Room and spread their palm and ask you if we have a stock of what is lying on his palm. The damaged part that needs to be replaced is in his palm.  On who will manage the Store Room, I will agree without thinking that it should be the Maintenance People responsible. Their very lives and existence on the plant would rely on them to provide Functional Equipment for Production, and without the necessary Spare Parts, their mere presence would count to nothing if they cannot replace the defective parts of their equipment.  The storeroom requires the collaboration of the End-user (Maintenance/What to Stock), Purchasing (Where to buy), Management (Budget), and Store Room (Location & Procedures). Without the collaboration of the persons involved in the process, it could mean long lead times (ordering to delivery), wrong items, and suppliers without after-sales support.  The algorithms for MRO Inventory Classification and Analysis are a big help when presenting to management regarding the need to write-off Non-moving and Obsolete Spare Parts. We should also know what kind of Stocks we have, as Finance/Accounting/Management might ask why we have so many items on hand and what kind of stocks are being kept. With the algorithms, we can give them a clear understanding of our stocks.


The need to measure Store Room Performance is a must-read for Store Room Personnel to assess our performance. As Peter Drucker said, you cannot manage what you cannot measure. This is how we will know our performance vis a vis the Maintenance Function. If we are experiencing many Stock-outs and Emergency Buying, then something is wrong with the Store Room Operations. The lives of the Store Room Personnel depends on their performance, and this can only be measured by the KPI's presented here. Store Room Inventory accuracy must also be maintained, or we might be accused of pilferage at the very least or worse with qualified theft. We just need to know how to measure our performance before our manager tells us to go home and stay at home since our performance is below par.  The chapter on whether to stock or not is also a big help to Maintenance Personnel with the given Factors to Consider whether to Stock or Not a Spare Part. The included MRO Decision Diagram is also a plus factor for Store Room personnel in decision making, whether to Stock or Not a Spare Part.  The recommendations of OEM suppliers should also be taken with a grain of salt since they are in business to make money while Rolly. Angeles, the author of this book, is trying to help us save our money.  Most of my Non-moving Stock is the Spare Parts recommended by the OEM Supplier and have been in the Stockroom for nearly 30 years, gathering dust.  The Problems and Solutions presented here by the author is an excellent reference for Store Room Personnel whose voice has gone hoarse, shouting to his managers for help in his work. With this book, he can just hand it to them with the instructions to PLEASE READ!!! ASAP.  All in all, I would like to recommend this book to all Maintenance Personnel, Management, or the One Man Army (Storekeeper). All of his books should also be made as a Reference for Engineering, Vocational, and TESDA courses.  Lastly, Sir Rolly, Thank You, God Bless, and Stay Safe.  From  Rolando C.P. Daclan, Spare Parts Supervisor, AB Heineken Phils. Inc. (ABHP), El Salvador Plant
