blue-sky thinking

blue-sky thinking — Blue-sky thinking means creative thinking with no limits, ignoring practical problems like budget or time for now.

In simple English

The idea is a clear blue sky with nothing in the way. In workshops, a facilitator might say "This is blue-sky thinking, so forget the budget." It is more common in UK English, and it is famous as a corporate buzzword that people joke about. In tech teams, "no-limits brainstorming" or "what if we had no constraints?" say the same thing in plainer words.

How to say it: Stress "blue" and "sky" evenly: "BLUE-SKY thinking".
