Can you tell us where you have seen the term "good efficiency?" That is not a term used that I know of. You are undoubtedly referring to efficiency, of which there are MANY different forms and measures of efficiency.
If you can, please provide a bit more information on what it is you are looking at.

I would say efficiency is quite simply the ratio of useful "stuff" over the total amount " stuff" available.
For example a light bulb has x amount of energy (electrical) available. It uses y amount of energy to produce light, therefore the efficiency is x/y x 100%. Good efficiency is about improving this ratio towards 100% Edit: Silly me, it should be y/x * 100%

"Good efficiency" sounds like a subjective term, where 'good' is simply an adjective. Then there is the matter of 'reliability' or 'availability'.
