trade-off

"In each plant, decisions need to be made based on the specific location and the resources available. It's all about trade-offs."

The prime minister said the time was "long overdue for Westminster politicians to level with people, honestly, about the trade-offs that Britain faces".

But a department insider rejects that characterisation, and says: “No one doubts the issue is huge, but any solution is expensive – everything is a trade-off.”

"It also helps decision makers to consider the inherent trade-offs when dealing with systems that extend across social, environment and economic domains."

The trade-off between the risks and benefits of being tested is “very nuanced, very personal”, Prof Ahmed says, and what is acceptable to one man will be unacceptable to another.
