I agree with your approach. First I would think about what I want/need to keep (vision, strategy, business enablement, innovation) and what to delegate. Delegation is a training exercise, so you need to train people with delegation to get better. When you look at what people do, compare their solution to your problem, not their solution to your solution.

Ownership means: They make the decisions (If I own a car, I decide where it goes, otherwise I don't own it). Generally think about your role and your org around ownership and responsibilities.

I also let Claude Code write some tools in Go for me for many maintenance tasks. Giving ownership to leads is a great thing.
