I'm sure we could all come up with a hundred such examples, Billy.
If the NHS supplies organisation (whatever it's called these days) was properly organised, biomeds would be able to request parts from the Hospital Stores and they
would be left to source the parts (carry the can, take the blame, procure the parts quickly and cheaply ... whatever).
Perhaps one day some Genius will amaze everybody by coming up with an idea called "economies of scale" - and start off by buying the batteries in question as a job lot from Panasonic and holding them against a stock number in Central Stores!
Meanwhile, those of us outside of the NHS shall no doubt carry on following Good Engineering Practices (aka
Common Sense) aimed at meeting customers' expectations in a timely, cost effective and efficient manner!
