I should have been clearer.
When I said that good leaders pay attention to things from the bottom-up, that doesn't mean they always know everything needed for any discussion. It just means they are able and keen to understand the low-level details when they matter, because they routinely look at such details in the projects that they're involved in.
Of course it's possible that this story is just told badly and the SVP already knew the technical details, in which case the blog post is a bit misleading.
> I need them to tell me what we're going to change, and it needs to be a BIG systemic change, not minutiae, which is where many engineers thrive.
How can one know if the engineers' proposed "BIG systemic change" is appropriate and complete, without knowing the details of the problem it is addressing?
