ur tradition of publishing annual, fact-filled PEM handbooks continues with this issue, The Reliability Handbook. soon As as the ink was dry on lastyear’s MRO Handbook went back to John Campbell and his team of experts at Pricewater, we houseCoopers to see if they could provide our readers with current and to-the-point information on the subject of reliability-based maintenance, along with the tips they’d need to put this information into action. Well, the team at PWC came through with flying colours, and what you’ll see on the next 72 pagesrepresents the cutting edge of reliability research and implementation techniques from a firm that’s one of the world’s leading providers of this kind of information to plant professionals around the world. All of us at PEM hope you enjoy it, and use it well! — Paul Challen
