Most Biomed departments in the NHS always have far more to do, than there is time available. It is no good just saying an infusion pump takes an hour, so thats 37 in a week. You also have to consider all the interuptions (cos we are always helpful).
If your department has been running properly, it should always be looking for better ways to do things without affecting the quality of the service.
As Bill has said, are the electricians going to be paid more for doing the same job? Where are they going to get their skills from? Besides which, don't they have their own jobs to do.
Nothing to do with Lean my friend. Stick to horses for courses.
