Effectiveness, Efficiency, Sustainability
At first, the only thing that counts is attaining the product in the first place, regardless of how, of its quantity and of its quality: is immediate survival ensured?
Then, instantly after this is achieved, it begins to be broken down into an exploded diagram of some other aspects each one of whom begins to count in itself:
Effectiveness: am I able to achieve an adequate quantity and quality of my target, whatever? And should it be beyond my personal forces, how do I achieve it?
Efficiency: how is the effort to result ratio? Is it possible to achieve more with less strain?
Sustainability: am I ensuring that what feeds me today will still be here and able to feed me tomorrow and my children the day after tomorrow?
