New techniquesdecision support tools such as failure modes and effects analysis, new techniques in maintenance such as condition monitoring, design of equipment emphasizing more on reliability and maintainability, major shift in organizational thinking such as towards participation, team work and flexibility.
world-class manufacturing modeltotal employee involvement, just in time manufacturing, total quality management, total productivity maintenance
just in time manufacturingzero defects, zero set-up time, zero inventories, zero handling, zero breakdown, zero lead time, economical lot size of one
total employee involvementemployee empowerment, improved communication, trust, teams, open offices, no "turfs", problem solving
total quality managementtotal = quality involves everyone and all activities in the company, quality =setting and conforming to Requirements ( meeting internal and external customer requirements), management = quality can and must be managed. continuous improvement, TQM = a process for managing quality; it must be a continuous way of life; a philosophy of perpetual improvement in everything done
total productive maintenanceTQM adapted to maintenance management, maintenance as an integral part of the quality program, action teams pinpoint trouble spots, operators take a very active role in maintenance
reliability centered maintenancea process used to determine what must be done to ensure that any physical asset continues to do what its user want it to do in its present operating context, matches maintenance approaches to machine, operation and expectations, each technique will be valid for certain situations, clearly identifies equipment functions, makes use of FMECPA

Question Answer
How do you know when there is a hazardobservations, history, tests, common sense, similar equipment, use published lists
Fault tree analysisuseful for identifying chains of events that could cause a failure (cause and effect, or causality) with AND and OR
Failure mode, effects and criticality analysisidentifies function, examines how each part of an assembly can fail and what that failure means for the overall assembly, component based
