Here's mine:-
1) Some sort of output results should be recorded for each PM, if only to 'prove' that the thing was actually tested. The previous results also help to give a clue to the next tech about what sort of output is being looked for! Basic electrical safety results could be jotted down, especially earth continuity, but, like Mark I would accept a pass/fail there.
2) Estates and biomed come at PM from a different perspective. Always have and always will. Software common to both departments will always be a compromise, at best (as has already been pointed out). And biomed will generally be the ones to loose out. Do like I did at a well-known hospital in a far-away Desert Kingdom; refuse to have the Hospital Engineer's lousy pet system foisted upon us, and get shifted to another hospital site as a result (where I used my own software)!
