feasibility frontier
Metaphor for production possibility frontier, doesn't seem to be a very major expression?
The production possibility frontier is "a situation where trade-offs occur in what can be made due to limited materials.
The feasibility frontier "has tradeoffs in what can be made due to technology limitations."
In English, it is called Technological Frontier, but this is tainted with the meaning of "amazing technology" in English as well as Japanese.
