There is much literature on work sampling studies—from useful to not useful. Useful if the studies are done properly, and dangerous if not properly done, which happens more often than not. This presentation will dispel the myths about wrench time by addressing some old-fashioned concepts and strategies that work, just like the kind you would find in classic Western movies, where the heroes have a clear vision, develop strategies and plans, take action, and don’t let obstacles get in the way. The Good, The Bad, and The Ugly was set during the American Civil War, where three men were determined to find $200,000 in Confederate gold coins that was ambushed by Yankees and buried in a remote southwest cemetery. But where is the value of finding gold in performing work sampling studies? That’s why you need to round up the horses, get the campfire lit, and settle in for an entertaining hands-on, informative presentation to learn about the good, and bad, and the ugly of work sampling studies to measure wrench time. Dennis Heinzlmeir has led 12 work sampling studies across Canada at various industrial facilities. He will reveal the results to support that when studies are completed in the right manner, they offer valuable benchmarks to organizations that lead them to drive down maintenance costs and increase uptime through continuous improvements. Ineffectiveness and inefficiencies can creep into a company’s work management process; having this health check can save millions of dollars. Just like a Western’s happy ending, this presentation will address the many misconceptions, misunderstandings, and myths about wrench time. Measuring wrench time is a very effective means of improving productivity if it’s done with a focus on removing obstacles and frustrations that prevent maintenance work from being completed efficiently and effectively.
