Efficiency is maximum output from minimum input

The beautiful definition of predators I read was 'one who burns the least amount of calories to earn the most amount of calories.'

In this context, "outputs" refers to concrete deliverables like shipping features, running experiments, and completing tactical work that directly contributes to team productivity.

Focus on outputs at the start of your careers and don't forget outputs even when you grow in your career.

"An eval like this" refers to creating LLM-as-judge prompts for automated testing, and "the pesky ones" means AI failure modes that can't be fixed by simple prompt adjustments.

For me, between four and seven. It's not that many, because a lot of the failure modes can be fixed by just fixing your prompt. You shouldn't do an eval like this for everything, just the pesky ones.

The three roles refer to product managers, engineers, and designers on product teams.

There's a strong advantage to any of those three roles who can kind of cross over into the other two. It really does become more about individual attitude.

I will define luck as opportunity meets readiness. Readiness is up to you; opportunity, not always.
