Chefs are able to do 10x output for things they believe in.

For things they don't believe in, where they're asked to be a line cook, they might only be 0.5x.

If you have a chef, and there are two equally risky options, but the chef believes in one, go with the one they believe in.

Even if it's not exactly right in the end, the 10x effort will allow it to be much more likely to be great.
