I think this is a really great list. It makes it very easy to measure the outputs of a productive engineer. However, I think there is important value in humility and reflection, which this list doesn't capture. This is why I would suggest including something like:

- Ability to identify gaps in own knowledge and willingness to discuss those limitations with peers.

I find that traits like this tend to promote a healthy engineering culture. It's very difficult to grow such a culture, and it needs to come from the top.
