You’ve probably heard (and maybe even said) the adage, “Good, fast, cheap. Pick any two, you can’t have all three.” When it comes to repairing equipment that is down, you are usually forced to choose “fast” as one of the two. If you don’t choose “good”, you’re likely to be repairing that equipment again. Yet, cost is also a factor and sometimes it is a very limiting factor.
One way to look at this problem is to set a standard for what constitutes “good” based on a cost/benefit analysis for each type of repair. Of course, that is best done ahead of time rather than while equipment is down.
Another way to look at this problem is you can modify the inputs to these three choices so each one comes at less cost to the other two. For example, you can inexpensively speed up the repair of a critical machine by storing special parts and tools in a locker near the machine. And you can do an upfront investment to increase all three simultaneously: technology, training, and equipment modification are all areas to explore.
