I first met Ron Moore in the early 1990s. He is known as an icon in the reliability community and is the author of an excellent book entitled What Tool? When? This book tackles a delicate subject that is both difficult and controversial.
Moore examines and contrasts the world’s most notorious and respected philosophies in the field of maintenance and reliability. These include lean manufacturing, kaizen, total productive maintenance (TPM), Six Sigma, reliability-centered maintenance (RCM), root cause analysis (RCA), predictive maintenance (PdM) and others.
Which of these philosophies does a user organization really need? Is there a priority order or logical sequence to their use? Which produces the greater benefit or return for the lowest risk or investment? How sustainable are they? These are all great questions that require an answer, especially for those seeking a major transformation in their maintenance and reliability programs.
For those of you in the reliability field, this book is a must read. Lectures and interviews with Moore can also be found on YouTube and in the “Rooted in Reliability” podcasts for an abridged understanding of his main themes.
