We recently ran some stats on various data sets and the data is compelling!
It always takes longer on average to do a maintenance task if it requires a material, a service, or a spare part. If you improve the time it takes to procure them, you see the average fix for work also fall. Whilst looking at the data, we also noticed that within a similar industry sector the general average for fix times (regardless of whether it included procured items) was vastly different. Why? We could understand why if we were comparing a pharmaceutical maintenance regime with say a power generation maintenance regime, but in the same industry sector? How different can the maintenance be?
In general, maintenance is the same everywhere. A mechanical technician can move between companies relatively painlessly - what changes for them is business process. It is exactly the same with Mean Time to Repair. You can affect the time it takes you to repair everything by applying different business processes.
If you would like to check your stats within your own organisation and you are a Maximo user please get in touch and I will send you the procedure to run so you can monitor your own MTTR. Who knows, if this proves popular we may be able to make the data available to everyone by industry sector and come up with industry best performance criteria. Heavens to Betsy, now there’s a thought!
