Your point 1. Yes, I think I did state in my post that I believe that Volumetric Infusion pumps are 'critical equipment'. The point I was trying to make was that if you look at the so called 'evidence' from the database, you could make a case for increasing the frequency of PM on those pumps.
Your point 2. Not sure I agree. Surely if you use an 'evidence based approach' you should use all the evidence available to you from the database i.e. from both scheduled and unscheduled work. Why use only bits of evidence.
Lastly, which so called evidence is more appropriate. The evidence from a database, or evidence from an experienced Techie'. Use the database by all means, but trust the Techie' I say.
