From what I've seen, there isn't a way to visualize equipment reliability-related stats over time. I have been able to do this manually, but it has required running a lot of individual reports.
For example, it would be nice to have a quick way to generate a plot of an equipment stat (e.g., MTBF, MTTR,...) at some desired intervals (monthly, weekly,...). So if we implement some changes to maintenance in February, I might look at this type of report for a visualization of any change in periodic MTBF during subsequent months.
Just a thought.
