Few root causes are as important to control as particles, moisture and excessive heat. good enough. Documenting best practice in work procedures conveys the need to do the right things right the first time and every time. • Lubricant starvation is a pervasive, yet largely unrecognized cause of premature machine failure. Moderate lubricant starvation is often difficult or impossible to detect. I recently wrote an article on this (see www. machinerylubrication.com/Read/29040/lubricant-starvation-dangers). Understandably, lubricant starvation impairs the basic functions of lubrication. Examine the subtle and countless ways starvation occurs. • Machine criticality and other risk factors should be used to properly establish maintenance priorities and focus resources. Controlling every possible failure root cause for each machine in a plant is wasteful and generally overwhelming. Knowing both the probability and consequences of machine failure is a much better way to optimize a program transformation. • Skillful, daily one-minute inspections are very effective at early detection of many common lubrication problems. This sounds simple enough, but most routine inspections are horribly inadequate (e.g., limited to such things as oil level and leakage). Blatant opportunities to detect and correct problems are generally unexploited. • Users typically only get about 10 percent of the available benefit from oil analysis. Most oil analysis programs have been whittled down to the bare minimum and are run by unskilled onsite personnel. Many critical improvements relating to the quality of sampling, frequency of sampling, quality of the test slate and interpretation methodology often remain untouched. • Education enriches the maintenance culture and is a strong impetus to change and improve the lubrication program. As educators, we've been closely monitoring the progress of our clients in advancing their Accelerating Adoption of Optimum Plant Lubrication Why are plants so slow in adopting and deploying optimum lubrication practices? This question has befuddled industry professionals for years. The basic attributes of the Optimum Reference State (ORS) are widely known and are certainly deployable. The benefits are also welldocumented by countless case studies, and the risks and costs are relatively low. So why hasn't the ORS reached a usage tipping point? I think a big part of the answer might lie in the Technology Acceptance Model (TAM), which was first introduced by Fred Davis. This widely referenced theory states that users come to accept and use a new technology according to a number of factors. These factors influence the decision of how and when it will be used, specifically: • Perceived usefulness — This is defined as "the degree to which a person believes that using a particular technology would enhance his or her job performance."

It's of little surprise that there is a correlation between the extent of program success and the level of education by personnel. • Procedure-based maintenance strengthens the awareness and importance of correctly performed tasks. Lack of procedures conveys that doing tasks any which way is instance, how do better contamination control practices influence the jobs of maintenance managers and their workers? • Perceived ease of use — Davis defined this as "the degree to which a person believes that using a particular technology would be free from effort."
