What's interesting is that there's nothing in the article that's actually specific to "non-technical" managers. In fact, reminding one to ask "what's the customer value here?" is advice that's probably more suited to highly technical managers rather than non-technical ones.

I agree... but it all depends on the role. Ideally, "management" can span the two buckets well. But, without understanding the technology, management is left standing on one leg.
