The welcome demand for the Maintenance Planning and Scheduling Handbook around the world and repeated printings have encouraged this second edition. The author is profoundly grateful that maintenance practitioners across a wide spectrum of industries have found the handbook and its principles universally applicable. The second edition has revised most pages throughout the entire handbook to clarify and amplify discussions based on the author’s experience of the last seven years and practitioner feedback since the first edition. Perhaps the most fundamental of these revisions is moving the planning strategy from simply relying on craft skills to more of a procedures-based organization in.
